Weighing

Use this function to access the features used with weigh stations. Weigh station features include weighing component requirements, weigh station calibration, and reconciling weights.

You can weigh components using 3 different modes:

• Weighing by WO (Weighing by work order)
• Weighing by product
• Weighing by production using the production (manufacturing) weight

You move to the weighing stages after selecting the component requirements.

You can carry out the component weighing in a single operation if a stock line has sufficient quantity available and if the weigh station has a sufficient range. It’s common to perform multiple weighings, according to the available stock and the range of the weigh station. Weighing scales can manage the potency of a product.

The Weighing by WO or by Weighing by product modes differ only when selecting the component requirement. Both modes weigh the components using incremental phase codes or codes to serve, for example:

• 2: Component weighed at weigh station
• 4: End of phase outputs weighed at weigh station
• 6: Production end outputs weighed at weigh station
• 8: Material correction at weigh station
• 10: QSP* at end of production

The selection of materials using the Weighing by production mode and the Weighing by WO modes are the same. Using the Weighing by production mode however, you can only weigh components weighed in production, end phase outputs weighed in production, production end outputs weighed in production, rework of materials in production, and QSP* at production end. The codes to serve are therefore 3, 5, 7, 9, and 10.

Prerequisites

Refer to documentation Implementation

Weight type determinants

There are multiple modes of operation for component requirement weighing:

• Accumulated weighing or By variance:

  • If the weighing is Accumulated, the selected weigh station and the receiving container can contain all the component requirement. You total the stock line weights in the same receiving container.
  • If the weighing is By variance, you change the receiving container for each stock line weighing for the same component requirement. You need another tare weight operation between each partial weighing of the component requirement.

  The weighing is accumulated if, and only if the weighing mode at the level of the component ICM record is accumulated, the packing at the level of the ICM record of the component is internal, and the weigh station has a sufficient range to weigh the component requirement.

• Weighing with or without a target weight: Weighing is with a target weight if, and only if specified for the weigh station and the weighing scale is connected. This document describes the weighing procedures without a target weight.
  For weighing with a target weight, the tare weight terms are identical, however the material weighing differs on the display of the weight obtained.
  The gauge and the "Weight obtained" display are initialized with (- weight to be weighed). The weighing goes from a negative value to zero (0). The zero corresponds to an exact weight.

  When the weight is carried out using supplier packaging, the initialization is made with (- weight to be weighed minus theoretical tare weight).
• Tare weight method: At the time of the first partial weighing of an accumulated weighing or for all partial weighings for weighing by variance, the tare weight of the receiving container needs to be established. If the packaging chosen for the weighing is a supplier packaging, the tare weight is automatic. A tare instruction is sent to the weigh station and you can pass directly to weighing the material. If not, you need to carry out a tare weight operation.
• Connection to the weigh station: the operation mode is different according to whether the weigh station is connected or not. If it’s connected, the program acquires the results of the weighing from the weigh station directly. If not, you need to enter the values.

Weighing function options

From the initial screen, you choose the mode to use with the weigh station. You cannot access the fields in this screen. They provide information to the weighing scale workstation that you are connected to, such as your user name and the date. The weigh station information gives the number of weigh stations connected to the weighing workstation and to be calibrated with respect to the total number of declared weigh stations, up to a maximum of 8 weigh stations.

Entry controls

Work order and operation controls: to authorize entry of a new work order or a new operation, the program checks if the work order or operation you would like to select has not been weighed in full.

Component controls: other than the same controls that are carried out on the work order, the program checks the following points for the component that you need to weigh:

• That the component is using one of the following codes to serve: 2, 4, 6, 8, or 10.
• If the component is an end of phase output weigh at weigh station (code to serve = 4). The components belonging to this operation need to have been weighed.
• If this component is a production end output (code to serve = 6). The components belonging to this work order and the end of phase outputs for this work order need to have been weighed.

Available buttons

Select this button to confirm the component selection screen and display the weigh station screen.
For an output where the quantity to be weighed is zero, as calculated by the system, selecting this button automatically completes this component. A warning message is displayed.

Select this button to carry out the box opening operation that corresponds to the selected component. If the operation or work order are changed, when the weighing has been carried out the empty box procedures at the end of the operation and the end of the work order are also available from this button.

Select this button to access the stock allocation table for the selected component.

Stock allocation

When you’ve selected a component to weigh, the stock lines need to be allocated to be able to cover the requirements for the component.

If you confirm your component selection, the program allocates the stock lines automatically.

If you allocate stock in the grid, you can modify the automatic allocations that have been proposed and print a list.

Displayed information

The grid presents the stock lines that the component requirements can consume.

The component code is displayed for information.

The balance to allocate corresponds to the component requirement minus the sum of the allocated quantities. For the materials, this quantity is expressed in a theoretical active unit and converted to the theoretical component unit.

For the materials, the allocated quantities in the table are expressed in a real physical unit, using the lot unit.

Weighing the component

Displayed information

The work order number, the operation, and the component are displayed for information purposes.

The lot and the location are used to identify the stock line currently being weighed. You can edit these fields if the UPDSTO–Update stock line parameter (GPA chapter, WEI group) is set.

The receiving container and the weigh station used for the weighing are displayed. You can modify these when the weighing operation initializes.

When lit, this indicates that the weigh station is connected. The program acquires the results of the weighing operation using its connection to the weigh station. When the connection is not established, in the Weight obtained field you need to enter the values that are displayed on the weigh station.

The total to weigh is the weight to be weighed to cover the component requirement. If the material is standard, this requirement is expressed in the theoretical standard from the product record.

The weight to be weighed is the weight to be weighed for the current stock line. It’s the allocated quantity for the stock line expressed in the lot standard for the standard components.

The security and risk logos displayed on the gauge are displayed as a function of the indications in the ICM record. These logos function like the buttons. The corresponding text is displayed when you select them.

Weighing operation preparation

The program automatically proposes the first allocated stock line while respecting the lot consumption strategy. You can edit the stock line if the UPDSTO–Update stock line parameter (GPA chapter, WEI group) is set.

The program automatically proposes a receiving container if the component ICM record specifies that the receiving container is a supplier issue (which is not modifiable) or internal. The proposed receiving container has the smallest capacity possible but can contain the stock line weight to be weighed if the weighing is by variance, or can contain all the requirement if the weighing is accumulated. If the recipient is mixed or if the receiving container is of the type supplier and several receiving containers are possible, it does not propose a receiving container and you need to enter one. You can modify the receiving container before the weighing operation starts. The entered receiving container is checked with respect to the weight to be weighed. It needs to be from a supplier or internal. It needs to conform to the ICM record. Its capacity needs to be sufficient for the stock line weight to be weighed or the total of the requirement, depending on whether the weighing operation is by variance or accumulated.

The program automatically proposes a weigh station. The proposed weigh station is not awaiting calibration. The total quantity to weigh added to the tare weight of the receiving container will be less than the maximum range of the weigh station. The minimum range of the weigh station is less than the theoretical tare weight of the receiving container. The maximum tare weight for the weigh station is greater than the theoretical tare weight of the receiving container. You can change the weigh station if the weighing operation has not started. The weigh station entered is checked with respect to the weight to be weighed and the tare weight of the receiving container. The checks respect the same rules as the proposal. If you are on the nth (n<>1) partial weighing operation for the component, the weigh station check does not prevent a weigh station whose status has passed to waiting calibration from being reused. This weigh station is only taken out of use at the end of the component weighing operation.

This button is displayed with the Lot, Container, and Weigh station buttons. Select it to access the tables for the stock lines, the receiving containers, or the available weigh stations. When the corresponding field is accessible, you can select it from these tables. Otherwise they are for display only.

You can also enter this information using a touch screen.

After you have entered these, you can start the weighing operation manipulations.

Weighing operation procedure

The weighing operation procedure is different according to whether the weigh station is connected or not, whether the weighing operation is by variance or accumulated, and so on. The message banner indicates which operations to carry out.

The partial weighing operation cycle when the weigh station is connected, is as follows:

You request to reserve the weigh station. You only take control when the program obtains a response from the weigh station.

You request a tare weight for the receiving container. You only take control when the program has obtained a response from the weigh station. The tare weight respects the tare weight tolerance defined in the receiving container record. The tare weight is displayed.

You request the weighing. You only take control when the program obtains a response from the weigh station. The weight obtained is displayed and the gauge evolves.

Select this button to confirm the weight. It then controls that the total weight obtained corresponds to the total weight expected at the tolerance appropriate for the product. 3 cases can occur:

1. The total quantity weighed is greater than the total quantity to be weighed.
   The system blocks it except for rework materials and the QSP.
2. The total quantity to be weighed is obtained from the last weighing operation.
   If the quantity weighed for this lot is less than the allocated quantity, according to whether the packing type is supplier or internal, the system completes the packing or a negative adjustment movement occurs. See the Appendix.
3. The total quantity is not attained (intermediate weighing operation).
   If the weight obtained is less than the weight available in the lot, a negative stock adjustment occurs. See the Appendix.

In all cases, the last weighing operation or an intermediate weighing operation, if the weight obtained is greater than that available in the lot a positive adjustment movement occurs. See the Appendix.

After confirmation, the program checks if this weighing operation finalizes the weighing of a lot, of a component, of an operation, or of a work order, and launches the appropriate procedures. These can be stock updates, tracking, document printing, empty box procedures if mandatory, and so on. If the weighing of a component is not finished, the program proposes the next quantity to be weighed. If not it returns to the component selection screen.

Updates following weight validation

After each weighing operation confirmation, the following operations are carried out: stock updates, tracking updates, printing the label destined for the receiving container, updating the weigh station used by incrementing the number of weighing operations if the calibration depends on the number or weighing operations.

If the validation of this weight corresponds to the end of a component run with all requirements weighed, the program deallocates all the allocated lots for this requirement and sets the status of the requirement to "weighed".

If the confirmation of this weight corresponds to the end of an operation, the program carries out all the operations of an operation end. In addition, it starts the end of operation document. If the empty box on the operation end is mandatory, it starts this procedure.

In addition, it starts printing the end of work order document and if the empty box at end of work order is mandatory, it starts the procedure. It sets the status of the work order to "Final packing complete".

Weighing operation procedure variant

If the weight is accumulated, the following weighing operations only contain weighing and confirmation. They do not need zeroing or the tare weight.

If the weigh station is not connected, in the Weight obtained field you need to enter the weights for the tare and the material. You do not need to zero the weighing operations.

If the receiving container is supplier packaging, the tare weight is carried out automatically from the theoretical tare weight.

Re-control

The program proposes the re-control if specified in the ITMCTL setup. You need to reenter the component, the receiving container, and the lot. The program checks that the values are the same as those online. This procedure is proposed before the tare weight if there's one. If not, then before the material is weighed.

Physical stock shortages

If the remaining allocations are less than the remainder to weigh, you are given authorization to reallocate stock to complete your requirement. Manual allocation is available using the lot inquiry screen allocation and deallocation buttons, and the selection buttons. Using this screen, you can complete the weighing operation without interruption.

Mode: Weighing by product

The Weighing by product mode differs from the Weighing by WO mode for the component selection. In the first screen, the component selection omits the selection of the work order, the component, then the operation. When you select the component, you use a second screen to weigh the component.

In the case of a weighing operation by product, the check concerning the phase changes are inhibited.

Mode: Weighing by production

You use the Weighing by production mode to weigh the components belonging to your current weigh plan, where the code to be used defines that it needs to be weighed in production. In the first screen, the component selection omits selection of the work order, the operation, then the component. When you select the component, you use a second screen to weigh the component.

Manual allocation is available using the lot inquiry screen allocation and deallocation buttons, and the selection buttons. Using this screen, you can complete the weighing operation without interruption.

Calibration

You use this function to calibrate the weigh stations individually.

Weigh station selection

In the first screen, only the weigh stations likely to be calibrated are displayed. These are the weigh stations without a calibration code equal to "No calibration". The included weigh stations are outlined in red and are not available for the weighing operation. These require calibration before you can use them again. According to their calibration codes, the weigh stations can be rendered unavailable for weighing as a function of the number of days or the number or weighing operations since the last calibration.

Each weigh station design functions as a button and takes you to the calibration screen.

The only other button available in this screen is the function exit button, which returns you to the welcome screen.

Calibration

The weigh station information is recalled and displayed on the calibration screen. It displays the weigh station name, its calibration record, and the number of lines of procedures to carry out.

Calibration preparation

The program automatically proposes the first line of the calibration procedure. You cannot modify this information. The line information that's displayed is the weight of the standard, the weighing operation type or position on the balance, the acceptable tolerance percentage, and the number of identical weighings to be carried out for this line.

Calibration procedure

The weigh procedure is different according to whether the weigh station is connected or not. The message banner indicates the operations to be carried out.

The calibration cycle when the weigh station is connected is as follows:

You request to reserve the weigh station. You only take control when the program obtains a response from the weigh station.

You request the weighing. You only take control when the program obtains a response from the weigh station. The weight obtained is displayed and the gauge evolves.

Select this button to confirm the weight. It controls that the total weight obtained corresponds to the total weight expected at the tolerance appropriate for the product. The program displays a confirmation message if the tolerance is not respected.

Updates following calibration confirmation

After each confirmation of the weighing operation, the value obtained is recorded and the next weighing operation for this procedure is proposed. When you’ve carried out all the weights for a calibration record, the program returns you to the weigh station selection screen. The current weigh station update is carried out as follows:

• If all the weights for the standard respect the tolerances, the calibrated weigh station is declared available. The date of the last calibration is updated with the current date and/or the number of weighing operations since the last calibration is reset to zero, according to the calibration code.
• If at least 1 of the weights obtained for the standard is invalid, the weigh station is declared invalid. The date of the last calibration is set to 99999999 and/or the number or weighing operations since the last calibration is set to 99999999, according to the calibration code.
• If a calibration procedure is interrupted, the weigh station is declared invalid, as above.

Weighing operation procedure variant

If the weigh station is not connected, in the Weight obtained field you need to enter the weights. You do not need to zero the weighing operations. You can use the touch screen to do this.

Data update

This function is available from the welcome screen. You use it to perform a new extraction of the weighing operation plan to consider any modifications in the work orders.

Appendix: Adjustment movements on weight confirmation

Confirmation of a weight:

If the total weight to be weighed exceeded and out of tolerance (irrespective of the packaging) error except for QSP and rework.

If not,

On the last weighing operation (total weight obtained = total weight to be weighed +- the tolerance)

Internal packaging

If the remaining quantity in packaging is greater than the percentage of the MP balance, the quantity weighed will be consumed. No adjustment movement will be made.

If the remaining quantity in packaging is included in the percentage of the MP balance, the message Complete packaging? Yes / No displays:

• If the weigh station operative responds "Yes", the quantity weighed for the MP is consumed and a final packaging movement is carried out.
• If the weigh station operative responds "No", if the remaining quantity is equal to 0, the system adjusts the stock line by 0.001 kg*. The weighed quantity is then consumed.

Supplier packaging

If the weight obtained is less than the weight to be weighed, there's a negative adjustment for the delta between the weight to be weighed and the weight obtained.

Intermediate weighing (total weight obtained < total weight to be weighed)

If the weight obtained is less than that available in the stock line, there's a negative adjustment for the total available**.

If the weight obtained is greater than that available in the stock line, there's a positive adjustment for the delta between the available and the weight obtained.

* If, on the system, the remaining quantity in the packaging is equal to zero but the weigh station operative refuses to complete or close the packing, a positive adjustment is needed to be able to reallocate the packaging for a different weighing operation. A final adjustment for the stock line is made at the time of the next weighing operation.

** The negative adjustments for intermediate weighing operations are not carried out for materials in adjustment or rectification. On the other hand, the rules are applied at the last weighing operation.
