PV550 Error - 684 Node not found

Hi,

I have a PV550 DH+ and a SLC 5/04. I just changed the 5/04 last sunday by another one and since the PV does not communicate with the SLC. The node of the PV is 12 and the node of the PLC is 13 (same as before).

I think that the problem is in the PLC I'm not able to see it in RSLINX. THE PLC is connected on a DH+ card onto CLX.

Any suggestions

thanks
Martin.

Baud Rate?

Problem fixed...I forgot to apply the new communication setup when I downloaded the program in the new SLC...
