We are in the middle of upgrading to 2018 from V7.2 and cannot get the IO servers that use ABCLX drivers to be redundant. If the primary is on and the standby is off data shows on screen just fine. Then when the standby is turned on the points all go to #BAD or #PEND (off and on, occasionally data does come in but then goes right back to bad/pend) . This also occurs if the primary is off and the standby is on and then the primary gets turned on. Does anyone have any suggestions for us to try?
