Figure 6.37 shows the input/output operation when a forced on/off operation is performed.
(2) Specifications
(a) CPU module status where input/output can forcibly be turned on/off
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 Y device.
(b) Registerable devices
Forced on/of can be registered as many as the number of I/O device points in the CPU module.
(c) Target input/output
The following input/output are targeted for a forced on/off operation.
• Input(X) and output (Y) of modules mounted on the base unit
• Input(X) and output (Y) of the CPU module to be refreshed from LX/LY of a CC-Link IE controller network
or MELSECNET/H module
• Input(X) and output (Y) of the CPU module to be refreshed from RX/RY of a CC-Link module
When forcibly turning on/off the devices outside the above refresh ranges (for example, empty slots), only
input/output in the CPU module device memory are turned on/off and the results are not output externally.
In multiple CPU systems, inputs and outputs of control modules can forcibly turned on/off.
Even when inputs and outputs of non-control modules are registered for forced on/off, the input/output devices in other CPU
modules and inputs and outputs of modules controlled by other CPU modules cannot be forcibly turned on/off. (The input/
output devices in the host CPU module can forcibly turned on/off.)
