Hi to everyone First of all sorry for my bad English.I want to make aprogram using an encoder up to 5KHz,two analog inputs to compare two analog values and then when the average value of them is within a setpoint ,i want to drive a motor.the motor will stop when the encoder counts a number of pulses.the number of pulses that i want must entered by display.Iam not familiar with Unitronics plc's.I have a decade experience in siemens S7-200 but i want to try with this brand also.What series and what model have to choose for my project? I need 10 digital inputs,two analogs and 6 outputs thanks to everyone in advance
