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.
Devices
All the inputs and outputs of the FC6A Series MicroSmart can be forced on/off individually.
Forced I/O Status
Events of the FC6A Series MicroSmart and effects on the forced I/O settings are shown below.
Note: Force function has no effect on high-speed counters, catch inputs, or interrupt inputs. The stop or reset input can be initiated using the force
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 forced I/O function status (running or stopped) can be checked in WindLDR, the FC6A Series MicroSmart error indicator LED
[ERR], or the RUN screen or STOP screen on the HMI module's LCD.
The forced I/O function execution status while stopped cannot be checked with the FC6A Series MicroSmart power indicator LED
[PWR] and the operation indicator LED [RUN]. For the power indicator LED [PWR] and the operation indicator LED [RUN], see
"CPU Module" on page 2-2.
The forced I/O may cause unexpected operation of the FC6A Series MicroSmart. Make sure of safety before forcing inputs or
outputs.
