I have an Idec HG1B Touchscreen that I would like to control a Model 485SDD16 (B&B Electronics) digital I/O module. The command structures of the two devices are different. Idec Tech Support says I need to write a new driver, and, oh, by the way, that can't be done right now. Their other recommendation is to replace the digital I/O module with a PLC that the HG1B already supports. That would be a (near) last resort. Any ideas?
