Note:
1. For the byte of “Interlocked relay pairs”, bit 0 means the pair of relay 0 & relay 1 and
bit 4 means the pair of relay 8 & relay 9. If bit 0 is set to 1, relay 0 and relay 1 is an
interlocked relay pair.
2. The interlocked relay pairs are effective in the interlocked mode. To set the
interlocked mode, please refer to Sub-FC 67.
3. For an interlocked relay pair, e.g. RL0 and RL1, three statuses are allowed:
Interlocked Status
Relay 0
Relay 1
1
ON (NO contact)
OFF (NC contact)
2
