(a) If the QJ71PB92V has gone down for some reason (the FAULT LED: ON, the
module READY signal (X1D): OFF), turning the Restart request signal (Y0D) OFF,
ON and OFF again restarts the QJ71PB92V.
(b) After the QJ71PB92V is restarted, the status is the same as the one after:
• The programmable controller is turned OFF and back ON again.
• The QCPU is reset.
This signal indicates whether or not the current operation mode is Communication
mode (mode 3).
