Previously Primary Controller goes in failure on restart after switchover?
I am using an 800xA System 5.1 FP4, and my range of controllers include PM861, PM864A and PM865A (Sil3) and everything seems to be correctly configured. All the controllers work in redundancy on start up with Prim and Dual LEDs lit as they should be.
The issue arises when I cause a fault in the primary controler (A). The seconday controller (B) takes over as required instantly. However the Controller A on startup goes in fault and does not startup. If I then give a power cycle to the Controller A, it then starts up correctly and assumes the secondary role as required.
I am facing this problem in all my controllers so it must be some issue with the configuration. I have set the secondary controller IP address from the IP Config Tool and since on intial startup the controllers do go in redundancy I do not believe the issue would arise from there.
Each controller has different modules on its CEX Bus;
PM861: No module, connected by TK850.
PM864A: BC810, CI854A.
PM865A: BC810, SM811.
Please also see the attached Controller Logs.
I have also confirmed all the firmwares so I do not believe the issue lies over there. I also increased the task intervals but to no use.
One point that I would like to clarify is in the IP Config Tool, I unchecked the Enable Autorestart; does this have any bearing on this issue?
Thanks and Regards,
