Micro Servo control with PLC

[ericksmith2 0]

I need help in choosing the right PLC version for me and I am not able to decide at the moment please help me. This is my first project with plc and I now understand that I don't know much about the things that a PLC can do and how can do. Thanks for help. My project includes control of 4 micro servo motors. While I was searching for the right PLC to do the work, I firstly chosen Siemens' LOGO! which I used before for some beginner projects. But here: 1.Can we use LOGO itself to drive a servo motor? question came up. All outputs are digital. I think I need expansion modules here. Then went to S7 series, Here the same question came up in my mind: 2.Can we use the Siemens S7-200 with CPU214 for servo control itself? Will we need anything more? On the other hand LOGO! has advantage of having screen to program which S7 doesn't. So I don't need to buy cable for LOGO! At the moment I think I will buy LOGO! but I think I will need expansion modules. On the other hand I don't want to use S7 for this small project. What do you think? What to do? ALso I need to inform you that using any type of PLC is an obligation. Thanks.

A LOGO is not really a PLC, its a smart relay. The S7-200 has been replaced by the S7-1200, if it is a small project, this is what I would go with.

what are micro servo motors? do you have link to a datasheet or picture? are you talking about hobby servos? to control those you need microcontroller, not PLC. PLC I/O are way to slow to produce required timing.
