6.2.1 Time Limits
Different time limits can be set for global or local forcing. Once the defined time has expired, the
controller stops forcing values.
The behavior of the HIQuad X system upon expiration of the time limit can be configured:
 For global forcing, the following settings can be selected:
- Stop Resource.
- Stop Forcing Only, i.e., the resource continues to operate.
 For local forcing, the following settings can be selected:
- Stop Program.
- Stop Forcing Only, i.e., the user program continues to run.
Forcing can also be used without time limit. In this case, the forcing procedure must be stopped
manually.
The person responsible for forcing must clarify what effects stopping forcing have on the entire
system!
6.2.2 Restricting the Use of Forcing
The user can limit the use of forcing to avoid faulty safety-related operation due to its improper
use. The following measures can be implemented in the configuration:
 Configuring different user profiles with or without forcing authorization.
 Prohibit global forcing for a resource.
 Prohibit local forcing for a user program
 Forcing can also be stopped immediately using a key switch.
To do so, the Force Deactivation system variable must be linked to a digital input connected
to a key switch.
WARNING
Failure of safety-related operation possible due to forced values!
Only remove existing forcing restrictions with the consent of the test authority
responsible for the acceptance test.
6.2.3 Force Editor
SILworX Force Editor lists all the variables, grouped in global and local variables.
For each variable, the following can be set:
 The force value
 The force switch (switching it on or off) to prepare for forcing variables.
Forcing can be started and stopped for both local and global variables.
Forcing can be started for a predefined time limit or for an indefinite time period. If none of the
restrictions apply, all variables with an active force switch are set to their force values.
When forcing is stopped, manually or because the time limit has expired, the variables will again
receive their values from the process or the user program.
If forcing is started again, the configured force values will replace the values from the program
or process!
