Today (HW) Interfaces Working Group Meeting #9

Here I would like to gather feedback on topic areas, such as the TF topic before, interfaces with PLC type hardware, and other topics to date, and gather any additional sub-topics of interest.

Have the minutes updated, you can check the link above.

We identified focus sub topics within the (HW)I WG and are open to more. Obviously the key is to have a champion for each sub-topic.

We also discussed some opportunities for guest speakers and synergies with other WGs. Looking forward to comments and/or participation as we get together in 2 weeks.

Hi Matt and thanks for organizing the WG.
regarding to the following sub topic I have some thoughts that want to share here:

  • PLC and PLC type devices - Doug shared info on this topic
    * Scope? - servos and drives? - gets into CAN Open then the PLC is simply a bridge.

There are great efforts already done in community to interfacing PLC devices but some how all of them are not maintained any more.

I’m using PROFINET for a while and already developed Ros control like HW interfaces for IO and PROFIDRIVE communication over Profinet to use a ROS based system instead of a PLC in industrial cells. This gives realtime control capabilities when it comes to Movement Synchronizations between robots and external tool axes.
On the other side of the spectrum , I’m using OPCUA for HMI integration in ROS based systems. I have extended the ideas and works above for some type adaptation between ROS and Siemens HMI specially in supporting arrays.

Now the point is does it worth making this libraries more general and more robust to be used as a plug and play module (with some configs for sure) inside the community like the other good developed modules like ros_control, nav and …
On the other hand there is also some new opportunities in the filed like PROFINET robot interface as is started to be adapted by robot manufacturers. I was thinking maybe we can also implement this Siemens Robot Library as a general interface between ROS and Siemens and any ROS Based Industrial robot be ready to use in Siemens & Co environments.

I would be happy to have you present this idea at one of the upcoming (HW) Interface Working Group meetings. I will be sending info about the upcoming WG meeting. We may shift out a week to line up with the existing ROS events invite, so stay tuned. Relative to OPCUA, I think there is a lot of interest in leveraging for interfaces. We have not had a lot of pull for profinet, but a supported profinet based interface would be interesting for those using other Siemens ecosystem solutions. Let me know if you would be willing to attend and offer up an approach.

It would me my pleasure to discuss it more in one of the upcoming (HW) Interface Working Group. Maybe we can start with OPC-UA for a while and later approaching PROFINET as OPC-UA is a hotter topic.

I have also discussed a little last week with @destogl about his ros_opcua_communication package and the potential he sees in GitHub - Mariunil/ros2-opcua: Communication between ROS 2 ecosystem and open source OPC UA PubSub implementation open62541.

I will prepare something to discuss more in the meeting!

Great. There is a meeting today, but I realize that is short notice. Let’s target the September 1 HWIWG meeting. I can send you a reminder/post up that you will share some of the concepts for that particular meeting. Thanks!
