Is it possible to change Freelance subnet mask in a network with redundant controllers?
Answers
It is possible to change subnet mask as 255.255.255.0, it is redundancy case, special ethernet setting. You need to set E1 card at '0' address for both the controller(primary and secondary) and E2 card at 'F'.You can set IP address and subnet mask through diagnostic innterface RS232, using disgnostic cable TK 890F or TK 891F. If you want to configure this in case of some testing purpose in lab or as inhouse activity then better contact to your IS administrator as well. because if you want to have AC800f controller on other subnet ( other then default one) for long time better to reserve IP against mac id of ethernet card, It amy be possible if there is DHCP on the same subnet and you power off and power on again your controller may be lost with IP address set before.
255.255.240.0 is needed for the time synchronisation.
you may change anything and everything but it would be good to know if all communication is working properly including time sync
