There are many different machines but the ones we are looking to replace the PLC and HMI in have 5 digital inputs and 4 digital outputs also they have2 analog inputs and 2 analog outputs for speed refence and temperature control through an rtd module. Temperature range should be 200f-600f The screen size is 3.5 inches and the resolution needs to be probably 14 bits for better control. I am in North America but the machines are world wide and many different enviroments. I work in the rebuild facility but am looking to get into new product development. I am educated in Allen Bradley brand of PLC's and HMI's but think this could be a very good replacement and I'm willing to experiment for the good of the company and would be doing this on my own to present to the right people.
