Forced I/O Function - IDEC SmartAXIS FT9Z-1A01 User Manual

Forced I/O function

Inputs can be forced on/off regardless of the status of physical inputs, and outputs can be forced on/off regardless of the ladder
logic using the forced I/O function in WindLDR. The force input function can be used to monitor or online edit mode to test the
ladder logic without the need of wiring the input terminals or turning on the actual inputs. The force output function can be used
to turn on/off the outputs to the external devices.
The forced I/O may cause unexpected operation of the SmartAXIS. Make sure of safety before forcing inputs or

function, but the force settings will be cleared as soon as the reset input is turned on.
Checking the Forced I/O Function Execution State
The state of the forced I/O function (running or stopped) can be checked with WindLDR, with the SmartAXIS module error status
LED (SmartAXIS Lite only), or with the RUN or STOP screen on the module's LCD (SmartAXIS Pro only). The forced I/O function
execution state while stopped cannot be checked with the module's power/run status LED. For the power/run status LED, see
