[UNIT LAY. DIFF.]
• In a redundant system, the module configuration
differs between the control system and standby
system.
• The network module mode setting differs
between the two systems. (This can be detected
from the control system or standby system of
the redundant system.)
■Collateral information
• Common information: Module No.
• Individual information: -
■Diagnostic timing
• At power-on/At reset/At tracking cable
connection/At operation mode change
• Match the module configurations of the
control system and standby system.
• In the redundant setting of "Network
parameter", match the mode setting of
System B to that of System A.
