I'm using Citect Scada 2018 R1 Update 16. i have this alarm on the hardware alarm for one of our IO devices. i noticed the IO device can only talk to the Secondary server .It use to function well though. i have checked the I/O Devices configuration priorities and they are set the same as other I/O devices; primary 1 and secondary 2. The affected I/O device is Control Logix 5555 however the other I/O devices which are working perfectly are GE RX3i controllers and Allen Bradly Micrologix .
Can anyone assist me.
