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

    Hello Guys:smiling_face:

    I have a simple material handling application where I need to share bits, integers and perhaps strings values to a s7-1500 PLC, I'm starting with Fanuc robots so perhaps my question is very basic but I still want to know before moving an used robot in a warehouse to site, my question is the next:

    Can I communicate a Fanuc R-2000iB /controller R-30iA with RTL-R538-HT (Ethernet IP) option to a Siemens s7-1500 PLC using the LCCF_EnetScanner function ?? :thinking_face::thinking_face::thinking_face: , I just want to be sure that this was done before and I can share bits/integers and perhaps strings, I found this information in Siemens website regarding the LCCF_EnetScanner function, link below

    SIOS

    Approved the thread.

    Your link is bad but I've found Siemen documents that support the use of a S7-1200 and S7-1500 acting as a EIP scanner. Their examples show the use between Siemen PLCs but it should work.

    Your PLC programmer will have a little bit of a job ahead of him but he should be able to sort out the raw data into the data types your robot is sending.

    I would NOT expect support for CIP safety in case your robot has that option.

    Hello jstolaruk , I was wondering if the RTL-R538-HT (Ethernet IP) will work to communicate the robot with a PLC because I tried to search the part number but I couldn't find it, the only thing I found was the description of this type of Ethernet IP adapters

    • Ethernet Global Data (EGD) IO (R793): This option allows your robot to exchange input/output data over Ethernet with other robots, eliminating the need for a PLC (Programmable Logic Controller). It simplifies connectivity by directly linking robots.
    • Ethernet/IP Adapter (RTL-R784): With this setting, the robot acts as a slave device within a PLC-controlled network. It communicates using a specific IP address, allowing it to receive instructions and send information through the network.
    • Ethernet/IP Scanner: Includes Adapter (RTL-R785): In this configuration, the robot serves as the master device on a network of slave devices. This allows the robot to control and coordinate the network activities.
    • Ethernet Safety: Requires Adapter (RTL-R713): This feature enables the robot to safely exchange input/output with a safety PLC, like Rockwell GuardLogix or Compact GuardLogix. It allows safety signals to be managed over Ethernet/IP, reducing the need for traditional wiring safety measures in the work cell.

    Do you know if the RTL-R538-HT can do the same than the RTL-R784?

    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 (low=fast) RPI (Requested Packet Interval) values. Additionally, you cannot run different protocols on the same port simultaneously (e.g., sharing Profinet and Ethernet/IP). If you are not handling highly critical timing tasks, Siemens will successfully perform the job. Additionally, you cannot send a string structure as a whole to the robot. This is only possible by encoding it byte by byte and transferring it in the form of characters. This process takes up a lot of space, and string conversions due to ASCII encoding are quite difficult.
