(12) Checking the redundant multiplexed remote master function
support and setting
With link special relays (SB) and link special registers (SW), whether the
multiplexed remote master function is supported can be checked and relevant
settings can be configured.
1) When the network module supports the redundant multiplexed remote
I/O networks, Host station's redundant function support information
(SB0041) is turned ON.
2) To set the time taken from detection of a data link stop until system
switching is requested in the redundant system, set a time value in
System switching monitoring time setting (SW0018).
3) If System switching monitoring time setting valid flag (SB0018) is
turned ON, System switching monitoring time setting (SW0018) is
enabled.
