• For the redundant power supply base unit or redundant extension
base unit, the power supply module status (power is shut off,
power supply voltage drop (not including a momentary power
failure) is detected, or an empty slot for the power-supply module
exists) is stored using the following bit pattern.
• In a multiple CPU system, the status is stored only to the CPU
module No.1.
• In a redundant system with redundant extension base unit, if
power-off or power supply voltage drop is detected in a power
supply module on an extension base unit, the state is stored only
in the CPU module of the control system, but not stored in the
CPU module of the standby system.
