Hi,
I have a Chromalox heater and the Tempererature controllers (6040 and 6050). Both controllers has the RS485 hook-up. I would like to know how to communicate with these devices. The devices themselves can function as an stand alone units with PID controller installed. These devices can be used with automatic or manual control. I would like to set it on automatic and control it from Labview. I am currenlty using the Fieldpoints modules with Labview 2009. I have several questions: 1. can I wire the RS485 2-wire connector directly to the field point module? 2. if I need an RS 485 converter, I will use the RS485 to USB. Would I then just use the RS232 visa? 3. there are two connection on the controller for the RS485, I am not sure how to wire that together as twisted wire. I have looked at the forum on the subjects and find bits and pieces of info.. I would like more directions.
Thank you,
