Setting Up and Using Extended Forcing

Using Protected Controllers

If you are using a PLC-5 protected controller, you must configure forcing online since, by their design, protected controllers cannot download forcing operations. This protects controller operation from possible force operations programmed in offline mode. For more information about protected controllers, see the PLC-5 Protected Controller Supplement, publication 1785-6.5.13.

Using Selectable Timed Interrupts (STIs) and Controller Input Interrupts (PIIs)

We recommend that you do not use forcible block-transfer data table files within STIs or PIIS due to the unique data flow of forcible block-transfer data. Block-transfer data that is written out or read in is never valid within the interrupt program file execution itself. Any necessary additional program scan time may defeat the purpose for programming the STI or PII.

Use your programming software to set up and use the extended forcing feature. The following table lists the software requirements for the extended forcing feature.

With the Programming Software	You Need this Software Release
Package
RSLogix5	2.0 or later
6200	5.3 or later
A.I. 5	8.03 or later
WinLogic 5	3.22 or later

To set up and use the extended forcing feature, you need to:

1.Select the group of data you want to force.

2.Use the programming software to enter or edit the data you want to force in the extended force configuration table.

3.Use the programming software to enter force values for the specified data table files.

4.Enable or disable the forces.
