ros-controls
Controller and Hardware Interface for I/O application
All industrial robots uses I/O to communicate with external environment. If I/O's are provided in controller level, it will be easy to control trajectory with I/O. I/Os can be digital or analog.
I have started to implement a prototype (msgs, HW interface, controller), but I had to postpone it for now.
can you link it here ? I am having problem in creating custom HardwareInterface for I/O.
@ipa-mdl We've started to do some work around generic ros_control hardware plugins for register-type interfaces (canopen, modbus, profinet, etc). If you're interested to perhaps collaborate on some of this, feel free to get in touch.
@ipa-mdl @mikepurvis: did you guys end-up taking this any further? I'm in a project that would need something similar and I'd like to avoid duplicating your efforts.
My underlying hw is not register-based, but that is an implementation detail.
@gavanderhoorn We've done some work on it, but it's not in a publicly-releasable state. If you're interested to take a look and see if it's a design direction which interests you, I can upload it to a private github repo and you can take a look.

Late reply, but yes, I would be interested.
Hi @gavanderhoorn, @ipa-mdl and @mikepurvis: Is there any news about these I/O HW interfaces?
I have already started wraping Profinet I/O and Profinet Drive(Telegram 111 and Telegram 3) profiles as ROS_CONTROL HW interfaces in a project to make a general Profinet HW interface compatible to existing position & velocity interfaces + non existing I/O interfaces.
That would be nice to know if there is any further advancement on this topic to be compatible with that and to avoid duplicating your efforts + of course contributing to what you have already started.
No, I don't have any news.
The offer by @mikepurvis was/is interesting, but I don't believe he found the time to upload what he referred to.
I'd still be interested.

do you have any repository where you're doing this?
I'd be interested to follow your development.
