AC450, MB300 & xA control network issue
the setup I've is redundant AC450 MB300 talking to xA via 2 CI855 through a managed switch set at 10HDR. Everything use to work as expected. Then one day without any change the link between MB300 and xA collapsed, couldn't get the OPC tags working until I disconnected 1st Network on MB300. Now the problem is I've swapped over all components and couldn't make network 1 work, also if network 1 is connected lot of red crossed appear on objects which are in 800M on xA. Not able to understand how MB300 network is creating problem on control network. Only place control network and MB300 can interact is CI855, other than this both network are completely isolated.
Ive changed all network components.
Change 513 card on 450, changed carrier board 520.
please help to troubleshoot it.
