Does anyone know of a PLC capable of reading/writing to 3 x RS232 devices.
PLC with 3 x RS232 Ports.

Have you looked at using a serial data splitter or multiple splitters? Or do you need three seperate RS232 ports on the PLC?

Any devicenet or ethernet/IP master capable PLC with Beckhoff KL60001 serial modules.

Do the devices have the ability to be addressed? If so, potentially only 1x serial port is required...

I assumed that they could not be. That is why I jumped to a device that could handle multiples. I was thinking that if any of us ask a question we have already when through the basic steps. I forget that this is a leaning place to ask starter and advanced questions. (Well I shouldn't assume anything look at some of my past question)

OP
Need to be addressed? Not sure I understand that question.
The application is as follows and requires very little coding I would imagine so a Compact Logix is over kill ( My problem , should have being more detailed)
Also I will be purchasing tonnes of these so I want it to be as cheap as possible.
I need to interface with 3 coin accepters. They are each connected to a MDB serial interface.
I need a way of programmably addressing each of them and be able to read/write to them.
I'm not so sure I could do this with a port splitter?
Anyone any advice on this would be great. Really requires very little coding with the exception of interfacing serially to these devices.

If you don't want to use a CompacLogix then maybe you could use the 1769-ASCII with a Micrologix 1500.

A couple years ago, I used a Beckhoff CX1020 with (7) RS232 cards. In theory you could use up to 256.
You could also use a Beckhoff bus coupler, such as DeviceNET, along with the KL6031 cards and add a large number of RS232 to any PLC. Probably not the easiest route when it comes to programming.

You could use a Phoenix Contact ILC130 PLC with 2 RS232 cards.
The base PLC has an RS232 Port on it. You program over ethernet so using the on board RS232 doesn't eat up your programming port.
Software is free.
