MB300 communication with CI855 and AC800M
I have a problem with CI855 card and communications with AC450. I have configured the MB300 network numbers and node numbers correctily (I think). I can see the AC800M node number from 800xA in the RTA board system status screen. I see all the values sended from the AC450 in the AC800M with zero values, but I am not sure that the DS Send from the AC450 is being received in the AC800M because I see the VALID param as 0, so it seems that the DS is not being sended. Somebody can help me to solve this issue?
Thanks



Thanks

Your node numbers seem to be wrong. The AC450 is sending to node 5. The AC800M is node 8.
Hi,
In addition to Rob's answer - look the manual AC800M Communication Protocols 3BSE035982-510:

I think you have wrong CAPos and Nodepos in MB300Connect block - there you should put the valid data for AS450 node's settings. Also look the settings of your CI855 in HW configuration - here you set network and node number for CI855. it has to be in the same network (11) with AC450 but with the unique node number. Also check MB300 protocol type and other settings.
In order to test your received data, in Online mode try to set Rd parameter of Receive block to a different value. In case it is overwritten by the other value, then the received values are coming from MB300 node.
In addition to Rob's answer - look the manual AC800M Communication Protocols 3BSE035982-510:
"The CIPos parameter specifies the position number of the CI855 unit in the hardware tree (identical to its position on the CEX bus). CAPos specifies the MB 300 network number, and NodePos the node position of the controller on the network."
