Starting Up The System - Mitsubishi Electric QJ71GF11-T2 User Manual

(4) Starting up the system

Reset the CPU module or power off and on the system in order of the local station, master station, and
submaster station.
Start up the master station before the submaster station. If the submaster station is started up first, it may operate as a
master operating station. Even if the submaster station operates as a master operating station, the master station starts to
take in control after it starts up. Then Data link status (own station) (SB0049) temporarily turns on, causing an error to be
detected. (This applies when "Return as Master Station" is selected in the "Operation Setting for Returning" field in the
supplementary setting.)
The LEDs on the master/local module are as follows.
