Create Logic in the Old DeviceLogix Ladder Editor Chapter 5
Forcing
To aid in the troubleshooting and debugging of your configuration,
you can force hardware inputs and outputs. No other inputs or
outputs can be forced from within the old Ladder Editor. Network
inputs and outputs can be forced in the device from where they
originated. If you exit the old Ladder Editor, the forced status will
remain in effect until you remove it.
The following list describes the input force options.
The following list describes the output force options.
When forced, the instruction turns yellow and the status value on the
connection reflects the forced state chosen.
To force hardware inputs and outputs (Force On or Force Off):
1. Right click on the element you want to force on or force off.
2. From the menu, select Force On or Force Off (whichever
action you want to perform).
When a bit is forced, its bit element will have brown text behind it
indicating that forcing is on or off.
TIP
If you force a Digital Output Point (DOP), the Comms Status
Override parameter on the Configuration tab in RSNetWorx for
DeviceNet software will be set to Override Enabled.
