CI855/AC450 MB300 communication problem
Hi guys,
I'm trying to establish a MB300 connection on site (AC800M HI via CI855 with redundant AC450). In the attachments I'm sending you the diagnostic pictures.
In my company, MB300 communication worked well (CI855 with MP200/1) via unmannaged switch. But here on site, I keep getting the message: "No Communication on port 1, No communication on port 2"; and "Node unreachable". The communication flows through mannaged switch, but every port has same settings, so there should not be a problem with that.
Does anyone know what could be the problem? A colleague proposed me to make a new "Master table" on AC450.
On 800xA DCS on RTA board communication graphic, I can see that all nodes are online, except the CI855 module. But this module is not imported into MB300 network control structure (only in control builder), so I suppose that's ok.
Thanks in advance,
Hrvoje

Is AC450 and RTA using MB300E while CI855 is set for regular MB300?
Do you have any hub/switch and spare/engineering RTA/PU410 unit with which you can try making a small ”test island” with?
CI855 - hub - RTA/PU410 - CBA?
Then SLTARG to CI855
Depending on circumstances you could try using one of the regular RTAs for this test.
Check controller logs of AC800M
Try getting System Messages from CI855 (difficult without SLTARG to it)

There is a good chance the Ci855 is 10Mbit half duplex, do you have tried the switch ports on auto negotiate or 10Mbit half duplex.

Switch ports are on auto-negotiation. On switch, there is already existing communication (RTA boards - port 4 and 5, AC450 controller - port 11, Safeguard controllers - ports 12,13,21,22). Picture is in the attachment.
