Small comms PLC

crewboss · Oct 31, 2015

Hello all!

Trying to find a small comms PLC to monitor a Centronics parallel port, and relay the data via RS232.

It needs to fit inside an old-style cash register, so a single-board bare pcb about 3" x 3" would be ideal.

The idea is to get a remote (back office) record of the chits.

All suggestions welcome!

Why not find a parallel port to ethernet converter and try that? Not sure if they still sell them new but they were common 10 years ago.

I don't think a PLC is the right tool here.

I'm sure that updating the "old-style" cash register to something that was manufactured in this century would be the way to go...

An Arduino would be a good fitting piece of hardware to do this. You need hardware with (11) 5 volt inputs and a serial port.

Closing thread

Many thanks for your help, one and all!

The client wants to keep the RS232 system, as it lacks transparency to certain elements of 'officialdom'

I was looking for a PLC solution because that is where my progamming skills lie.

Finally, I found a converter by Patton Electronics which I think will do the job just fine!

Tim.
