howdy all,

Have an application for a new build where I need to utilize an “HF” (high feature) Remote I/O system that allows isochronous functions down to a module level.

For all the high-speed or robotics machine builders out there, what are you using that has full supoort for Profinet IRT? Do you stick with what your PLC brand offers (i.e ET200SP “HF” coupler/modules)? Do you have a go-to that works down to the module level that *is not* Siemens?

I’ve used a wide variety of remote I/O systems in the past for standard applications - but the big players (outside of Siemens/Beckhoff) seem to ignore this market. Have tested Wago 750, Helmholz TB20, and Weidmuller stuff I have on hand; none fully support IRT at the module level.
