All experts,
This is my first time to use PLC (EZPLC from EZAUTOMATION.NET) to make a 6-ch temp controller using pt1000 RTD. The RTD I/O module I bought from them does not work (admitted by exautomation.net). I use a current source going thru the pt1000 to generate a voltage. Then I use the anolog voltage input I/O module to input to the PLC box. The goal is to use the temp sensor to control a heater and a LN2 (liquid nitrogen) solenoid switch to regulate the chamber temperature. However, I never worked on PLC before. Please advise how to start this and any example program (of any application) would be very helpful to me to get it started. Any your expert comments would be very much appreciated. Thanks a million in advance.
