Freelance: Can you use subnet 255.255.255.0 instead of subnet 255.255.240.0? Trouble with time synchronisation?
Voted best answer
Yes you can use 255.255.255.0. The fundamental is If other subnet mask than 255.255.240.0 are used, make sure that they are contiguous. The equivalent bit pattern must start and then continue with 1 value. It may change to zero once and must then end with zeroes.
But, following should be takne care:-
- To permit time synchronization, all stations must be in the same subnet.
- When using redundant AC 800F process stations, the subnet mask 255.255.240.0 must be used
- System time synchronization only occurs if the clock time has been set at least once by the engineering station using Options > Set System TIme in Commissioning mode.
