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.
Operation
Forced on registered
Forced off registered
Forced on/off cancellation
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
