Greetings to all forum members! I am encountering an issue while attempting to connect two PCs simultaneously to control a single PLC through MX OPC and KepServer. Is there a solution available for linking these devices? Any additional information would be greatly appreciated. Thank you, James.

James McQuade welcomes you to the forum. I encountered an issue while trying to connect two computers to control one PLC simultaneously using MX OPC and KepServer. Is there a way to connect them together? More detailed information is needed. I am using one PC to control the PLC through Node-RED using both MX OPC and KepServer, and another machine to control it through SCADA using these two software as well. Now, I am looking for a solution to use both Node-RED and SCADA simultaneously to control the PLC.

I utilize a single PC for PLC control using node-red with both mx opc and kepserver software, and another PC for control via SCADA with the same two software. I am interested in exploring how to simultaneously use both node-red and SCADA for PLC control.

When working with Node-RED and SCADA systems, it is beneficial to maintain separate tag sets for each. Within the PLC programming, combine these tags using logical OR operations to achieve the desired functionality. This approach is particularly useful when a single PLC needs to communicate with multiple HMI software systems. While attempting to write in Vietnamese, I noticed that my conversational skills are stronger than my written proficiency.

It seems like there could be a conflict due to the fact that both MX OPC and Kepserver are listening on the same port. Have you considered assigning each application its own port? Alternatively, there might also be a middleware solution to interface between the two PCs and the PLC. This could provide a controlled way to queue updates and distribute them properly between the two PCs.

Sure, it's possible to connect two PCs to control a PLC simultaneously, as both MX OPC and Kepserver support multiple client connections. The key factor to consider is your network setup. Ensure the network is robust enough to handle the connections and there's no firewall or antivirus software blocking the connection. You may also need to check the configuration settings in both software to ensure they're set to accept multiple connections.

Certainly, ensuring both PCs have access can be a tricky process. You might want to consider establishing your OPC and Kepserver on a single machine first and then use a network bridge to connect both PCs. A bridge would allow both PCs to communicate with the server. However, both these PCs should be on the same network for successful connection. In the case of different networks, consider opting for VPN so the traffic is secure. Always remember, network architecture plays a vital role in scenarios like this.
