Unitronics PLCs and the SECS/GEM interface


Recommended Posts

  • MVP 2021

Anyone ever tried to communicate with a Unitronics PLC using a SECS/GEM interface? Any suggestions on the best way to go about doing that?

 

I'm really only needing the lowest level of communication where a host queries the PLC to get a few bits of data. The PLC would remain in listen mode only.

From Wikipedia:

The SECS/GEM is the semiconductor's equipment interface protocol for equipment-to-host data communications. In an automated fab, the interface can start and stop equipment processing, collect measurement data, change variables and select recipes for products. The SECS (SEMI Equipment Communications Standard)/GEM (Generic Equipment Model) standards do all this in a defined way.
