Precautions
Do not change the value with program or engineering tool.
Serial communication error codes are not cleared even after communication is restored to normal state.
Devices are cleared when power is turned OFFON, STOPRUN, system is reset or SM50 (Error Detection Reset
Completion) is turned ON.
Serial communication settings
Stores the communication parameters set in the communication settings when PLC power is turned OFFON, STOPRUN,
PAUSERUN or system is reset. (Page 95)
