OS not active on MB300 net. RTA problem?
As some of you may notice, I've lately been posting about a troublesome Advant OS.
This is another question regarding the same OS.
After it got up and running, it was clear that the OS did not connect to the MB300 network. We have two networks, 31 and 32, and we suspect that out Hirschman switch for this connection is failing for net 31, i.e. the OS should only connect to the 32 net properly.
The reason behind this discovery was that after I installed the displays, none of the objects tied to a tag were visible. All numerical fields, level indicators, bars etc. were black. This is depicted in figure "skjermbilde". When clicking on one I get the message that "the indicated object tag nr. doesn't exist".
When checking system status, the OS only sees itself on the net. Up in the left screen corner it states network name, net and node, which is; OS41, 31 and 41. It seems for me that the OS stays in network 31 even though this network is unreachable from this position, and it does not switch to network 32. This is depicted in figures "system_status1-3".
I have no clue here, and, although I suspect this to be RTA card related, I really don't know. The RTA card used is PU531V2.
can anyone help me here?
