I am interested in adding an Ethernet module to the PLC5 CPU 1785-L20B/E and would like to know the proper installation location. Additionally, I would like to know if Ethernet communication is possible between this controller and the ABB PM861. Thank you for your assistance.
To ensure seamless communication between your devices, consider integrating ABB's Communication Cards such as the CI868 Modbus card. From there, you can connect to a PLC 5 Modbus card. While ABB also offers the CI873 (EthernetIP) card, compatibility with PLC-5 Ethernet is uncertain due to potential differences in protocols and port numbers. It's important to note that my experience with this setup may vary from your specific hardware configuration. Feel free to reach out for further clarification.
For the PLC5 CPU 1785-L20B/E, the Ethernet sidecar module you're looking for is the 1785-ENET. It should be installed in the dedicated communication port of the CPU. As per the second part of your question, yes, it's feasible to have Ethernet communication between the PLC5 and ABB PM861 controller, given that both controllers use open standards. However, you'd typically need to use a device like a gateway to convert protocols since the ABB controllers usually use Profinet or Profibus, whereas PLC5 is Ethernet IP. I'd recommend hiring a seasoned systems integrator to set up this communication link, as it can get a bit technical.
Adding an Ethernet module to your PLC5 CPU 1785-L20B/E is a great way to enhance connectivity! The best installation location for the Ethernet module is typically in one of the empty slots in the chassis where your CPU resides, but just make sure to consult the user manual for any specifics related to slot availability and compatibility. As for communication with the ABB PM861, it can be a bit tricky since the PLC5 series primarily uses older, proprietary protocols. However, with the right configuration and possibly additional hardware or gateways, Ethernet communication should be feasible; just keep an eye on the specific protocols used by both devices to ensure compatibility.
To add the Ethernet module to your PLC5 CPU 1785-L20B/E, you'll want to install it in one of the available I/O slots on the chassis, typically right next to the CPU for optimal communication. As for communicating with the ABB PM861, it can be done, but you'll need to ensure that both devices are configured properly for TCP/IP communication. It might take some extra setup, especially since they come from different manufacturers, but it’s certainly achievable!
