Can someone recommend a manufacturer of cost effective PLCs for simple relay logic replacement, but will also give expansion options for additional analogue I/O if required. I have traditionally used Allen Bradley/ Modicon and feel a bit out of touch with what is currently available.

A glance through the RS Components Book will give you an idea what is popular.
What I/O ? .. how much expansion ? The Siemens LOGO is an excellent relay replacement but little I/O and not exactly expandable. Omron and Mitsu are OK with more I/O but not exactly modular. The cost of software has always been a factor for choice - are you programming 1 or 50.... Modicon was replaced by Schneider some time ago, not the same I'm afraid. For Allen Bradley think Rockwell which is not the same either, but they do small and modular but watch the price of software. Hope this helps |

Look at the Siemens S7 1200 PLC (a replacement for the S7 200).

I would try Mitsubishi. Siemens can be hard work if you are not using it every day.

I am totally agreed with john as mitsubishi are very user friendly and their programming is just easy i mean easy and you can master them in just couple of hours if you know ladder logic .

After working with many different type's of PLCs, I feel thats Mitsi are the best. But it depends if your going to use it to its full potential!
You say that you are going to replace simple relay logic, so if thats the case. A simple Moeller easy PLC might suffice, there are many different types of these and they are small handy PLCS that have different control voltages, supplies, many inputs and outputs, easy to program via the screen on the front or laptop and also some of the PLCS have room for expansion. Hope this helps Adam ------------------------- Fail to prepare...Prepare to fail! Adam |

I am looking for a cost effective PLC, with a couple I/O inputs. It will need to be able to do calculations. I am building a complex DC battery monitoring system. Ease of programming and most importantly cost is important as I am a broke college student. Any and all help is greatly appreciated.
