Hooking up two wires and a shield for an analog interface beats reverse engineering a drive even on a bad day. ;-) Andy, you would not have any problems using Modbus, but if the drive parameter to register interface is not documented, then you are shooting in the dark. If they are not providing docs, chances are they have issues with the Modbus implementation and the interface is intentionally not fully documented. It should not be that difficult, regardless of your view on information theory. :-) Dave ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
