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.
currently I have many problems for a new intallation while connecting MB300 via managed Cisco switch.
I few days ago I replace the switch by an unmanaged switch and it seems most of my problems are gone.
Give it a try replacing the switch for MB300 network.
A short feedback would be appriciated.
When problem exist, connect to CI855 and AC450 with OnLine Builder (yes, you can do SLTARG to a CI855).
There ought to be System Messages output. Please describe them with 100% details.
What do you transfer between AC450 and the CI855? Probably data sets, right? traditional programming skills of DS says "Do not put more than two DS in the same CONTRM" - if more than two DS are to send, you should split them over more CONTRMs, or else you may fill output channels in the controller. When so happen, System Messages will be output.
Remember that System Messages can be disabled to screen (and only sent to log). Enable them to screen and copy entire output to notepad and upload here please.
