Hi guys, I'm having problems with Modbus TCP/IP communication using CP443-1. I have a redundant S7-400 rack with CPU 412-3H (6ES7412-3HJ14-0AB0) and two CPs (6GK7443-1EX30-0XE0) in redundant mode communicating with only one Modbus comm gateway in a Bently Nevada 3500 system via a Scalance x208 (6GK5208-0BA10-2AA3). Refer to the "System topology.pdf". To communicate this components we use blocks MODB4 and MODB4H that now is obsolete I think. Some days ago we had a power interruption in the panel rack and now we can't reestablish the communication with the a Bently Nevada rack. We tried to restart, recycle the power and switch over between the CP's but nothing solved the problem. Dou you have any ideia how can I solve this problem? Thanks AttachmentSystem topology.pdf (247 Downloads) |
