The controller that he already has is Modbus, but I am not sure how well that integrates with Realtime/HAL Googling shows that Classic Ladder speaks Modbus, so I might want to retract my previous statement about the usefulness of the Pixsys controller. It seems like it might be possible to connect that to EMC with Modbus and Classic Ladder. I am not sure what is involved in getting RS485 communications configured at the PC end. There are USB-RS485 converters available (http://www.robot-electronics.co.uk/acatalog/Serial_Interface.html for example) and also RS232-RS485 adapters even more cheaply. -- atp ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
