Publication 1753-PM001A-EN-P - November 2005
5-6 Monitor and Force Signals
Force Time The force time is monitored by the controller. To enter the force time
in seconds, the controller must be in RUN or STOP mode with Forcing
allowed set. For unlimited forcing activity, enter ‘-1’.
The force time begins when the force process starts. The time is reset
to 0 if a new configuration is loaded or if the operating voltage is
disconnected.
After the specified time, forcing activity ends. If the controller switch
Stop on Force Timeout is enabled, the routine returns to STOP mode
when forcing ends. If Stop on Force Timeout is disabled, the routine
continues with the current process values once forcing ends.
Start Forces To start forces:
1. Choose the Start… tab or choose File>Start.
2. Enter the Force Time in the Start forcing dialog box and click
Start.
Field Description
Signal The name of the signal you want to force.
Force The value you want to force the signal to have.
The value you enter must match the type displayed in the Type field.
F (force mark) A check in this field identifies that the force value you entered is sent to and saved in the
controller and will become active when forcing is active.
Double-click in this column to mark that you want the controller to use this force value rather than
the controller’s process value.
Type Displays the type of the signal, as defined in the signal Editor.
R-Value (resource value) Displays the controller value, resulting from the current process and program logic.
R-Force (resource force value) Displays the value of the signal while forcing is active.
RF (resource force mark) A check in this field identifies that the controller is using the force value rather than the process
value as soon as forcing is active.
