3.18 External Input/Output Forced On/Off
This function forcibly turns on or off the external input/output of the CPU module.
(1) Input/output operation when a forced on/off operation is performed
Three types of forced on/off operations are available as shown in the following table. The following table shows
the status of input (X) and output (Y) when a forced on/off operation is performed. Note that a program operation
takes priority when a contact of output (Y) is used in the program.
The following shows the input/output operation when a forced on/off operation is performed.
(2) Specifications
(a) CPU module status
Forced on/off can be registered regardless of the operating status (RUN/STOP) of the CPU module. Note,
however, that only input can be forcibly turned on/off during a stop error. The CPU module outputs on/off data
only to device Y.
(b) Registerable devices
Forced on/off can be registered as many as the number of I/O device points in the CPU module.
(c) Target input/output
• Input (X) and output (Y) of modules used in the built-in I/O function.
• Input (X) and output (Y) of connected modules
• Input (X) and output (Y) of the CPU module to be refreshed from RX/RY of a CC-Link module
Operation Input (X) operation Output (Y) operation
Forced on registered
The CPU module performs program operations
using inputs forcibly turned on.
The CPU module outputs "on" externally regardless of the
results of program operations.
Forced off registered
The CPU module performs program operations
using inputs forcibly turned off.
The CPU module outputs "off" externally regardless of the
results of program operations.
Forced on/off cancellation
The CPU module performs program operations
using external inputs.
The CPU module outputs the results of program
operations externally.
