SIEMENS S7 1214 with FANUC ROBOT via LCCF_EnetScanner LIBRARY

    Hello everyone... I’m trying to use this library to exchange signals and data with a FANUC Robot. The communication works, but it’s really slow. Keep in mind that, for example, if I activate an output on the Robot, I can see it on the PLC only after 400/500ms. I wasn’t expecting miracles from this library, but neither this kind of delay. The Cycling interrupt [OB30] that handles the communication has a clock time of 10ms. I’ve also tried decreasing it to 3ms or increasing it to 100ms, but there’s no noticeable improvement.

    From a hardware perspective, I have a CPU 1214C FW 4.5 connected to a PC running WinCC RT and the FANUC Robot LR Mate 200iD V9.30P/33 and the 1A05B-2600-R784 Ethernet/IP Adapter

    Has anyone achieved better results with this library?

    I've done Siemens to Fanuc but always used Profibus or Profinet and didn't experience delays like that. So, no experience with the Siemens acting as a EIP scannner.

    Ever use Wireshark? You could monitor the traffic and see if the delays are present at the lowest level. Connect and disconnect the HMI to see if there is any change.

    Under normal circumstances, Siemens is not a PLC designed for Ethernet/IP and optimal performance. However, you can check your RPI settings. A value of 32ms is recommended for both communication and stability. If you still encounter latency issues, unfortunately, there is not much that can be done. In such cases, you may need to choose a PLC specifically developed for this purpose, such as Allen-Bradley, Omron, or Beckhoff.

    RE: Fanuc RTL-R538-HT Ethernet IP communication to Siemens s71500 PLC

    […]

    I don't know what the code 'RTL-R538-HT' refers to, but you can communicate with Siemens PLCs between Fanuc using Ethernet/IP Adapter or-and Scanner option packages. However, it's important to note that Siemens PLCs are not natively designed for the Ethernet/IP protocol. They have certain limitations in this regard. If you want to use a genuine Ethernet/IP device, Rockwell PLC (Allen Bradley) or Omron would be excellent choices for this purpose. With Siemens PLCs, you should avoid using low…
