DDE/OPC configuration and ML1400

[plaurent]

I've got an AB ML1400, and use the CPR9 SR2 release of RSLinx Classic to configure the DDE/OPC topic for the PLC.

Although I have 16 inputs configured on the PLC (I:0/0 through I:0/15), I can only see I:0/0 through I:0/7 within RSView's (CPR7) tag editor, and ditto with external OPC software as well (so it doesn't appear to be just an RSView issue).

Anyone able to shed some light on this issue?

Many thanks in advance for your time.

I:0.0 thru I:0.7 are the inputs on the base unit. But those aren't bit addresses they are words. I:0.0/0 thru I:0.0/15 are the first 16 digital inputs.
