[DESIGN PRECAUTIONS]
DANGER
Create an interlock circuit on the program so that the system will operate safely based on the
communication status information. Failure to do so may cause an accident due to an erroneous
output or malfunction.
When an error occurs, all outputs are turned off in the MELSEC-ST system. (At default)
However, I/O operations of the head module and respective slice modules can be selected for the
following errors:
(1) Communication error ( MELSEC-ST CC-Link Head Module User's Manual "4.3.1 Output
status setting for module error")
(2) Slice module error
The output status for the case of an error can be set to Clear, Hold, or Preset with a command
parameter of each slice module. (For the setting availability, refer to each slice module manual.)
Since the parameter is set to Clear by default, outputs will be turned off when an error occurs.
This parameter setting can be changed to Hold or Preset when the system safety is more ensured by
holding or presetting the output.
