Forced I/O
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 in 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 can be used on CPU modules with system program version 200 or higher and WindLDR 5.20 or higher.
Caution
The forced I/O may cause unexpected operation of the
MicroSmart
. Make sure of safety before
forcing inputs or outputs.
Devices
All the inputs and outputs of the
MicroSmart
can be forced on/off individually.

Forced I/O Status
Events of the
MicroSmart
and effects on the forced I/O settings are shown below.
Events
Forced I/O Status
When the MicroSmart starts running
The force settings are retained. The forced inputs and outputs are kept
on/off even after the MicroSmart is stopped, regardless of the status of
M8025 (maintain outputs while CPU is stopped).
When the MicroSmart is stopped.
When the MicroSmart is powered up
The force settings are retained, but the force is suspended. If the bat-
tery is dead, the force settings are cleared.
When user program download is executed
The force settings are retained, and whether the force will be sus-
pended or not can be selected in the Download Program dialog box.
When Run-Time Program Download or Download Test
Program is executed
When Confirm Test Program or Cancel Test Program is
executed
The force settings are retained.
When Reset Input is turned on
The force settings are cleared.
When Clear All Devices is executed in the PLC Status dia-
log box of WindLDR
When the system program is upgraded
RUN LED
RUN LED flashes while inputs or outputs are forced on/off.
RUN LED Status
Description
Slow Flash (1-sec interval)
Inputs or outputs are forced on/off while the MicroSmart is running.
Quick Flash (100-ms interval)
Inputs or outputs are forced on/off while the MicroSmart is stopped.
Notes:
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.
Inputs or outputs can be forced while WindLDR is in monitor mode or in online edit mode.
