Hi all, I am required to do a project to connect someone's existing Sauter Syteem/Control equipment to a pc. I am not able to find their URL. I basically need to know if they implement a RS232 or equal in their model ERA 140F001. I have no clue to their contact. The manuals for this HVAC PLC are lost and no body at the location seems to know about them. Any help would be more then welcome.
