Hi everyone,
I have recently installed Siemens CP343-1 lean Ethernet modules (firm V3) on existing production line machine PLCs. Installation of the modules went fine, and I am able to now see the entire plant using Siemens PRONETA.
The purpose of the install was to:
1) Upgrade the network from MPI to Ethernet
2) Connect all production line machines to a Kepware OPC server which in turn talks to an OPC UA client that is part of a new OEE/quality production monitoring system.
Following the exact same install process from a S7 hardware perspective, along with identical Channel/PLC setup in Kepware, I am now able to extract data via direct addressing from machine PLCs via the Kepware server (no connections from the machine PLC CPU to the OPC server were needed to be created in Netpro.)
My problem is the following:
Out of the 24 PLCs that are connected to the OPC server, 4 PLCs connections to the server constantly drop out.
Upon inspection of the CP343-1 lean units, the 5V and Run LED are lit solid Green, along with Port X1 LED lit solid orange. The RX/TX light is not flashing, and Ethernet coms to the PLC cease. Using MPI, I have checked both the CPU and CP card online for any diagnostics. No error exist.
Cycling power on the PLC re-establishes RX/TX functionality to the CP343-1 lean module, and I am able to see the unit once again in the OPC server. However after a non constant time period, RX/TX function stops and I lose coms to the server.
I am at a loss to what is causing the issues.
Further info:
Each line is connected as a STAR system with all Ethernet coms being sent through a single X200 series switch. This central line control switch is connected to the server via fibre through a media convertor.
All parts are Siemens.
Any help would be greatly appreciated.
Cheers
