Arduino with advancedHMI

So far this excellent product only seems to work with a couple of PLC drivers including Allen Bradley and systems with ModBus protocol.

I've sent an email to 'support@advancedhmi.com' to test the water to see if they have/intend releasing a basic RS232 driver of some form suitable for microcontrollers like PICAXE & Arduino. Let's see how/if they respond otherwise I suppose someone needs to do a PLC driver which is well beyond my ability.

Does anyone see any other options?
