Gary,
Are you looking at "/STATUS" or "/ST"? In my application (admittedly nearly 10 years ago) I used "/STATUS" which gave me a string rather than a value. The screenshot is for an ET200M rack with 4 cards (first 3 slots are the empty dummy slots it required.

I currently do not have access to an EPM PB Master, but the procedure should be similar in any control system. I'll use a Prosoft PB DP Master as an example:
This is the hardware configuration of the PB segment. You can see the DP Master and an ET200 slave. Open the properties window of the slave. Three tabs should be available: Common, Parameter assignment and DPV1
Go to the DPV1 tab.
by default, ET200's head station (IM153-2....) is configured as a DPV1 slave.
Uncheck the DPV1 option, click Ok. You are done.
Of course, you must download the new HW config to the DP master and restart it to see the changes.
In the Parameter assignment tab, you can enable or disable some diagnostics parameters and data formats if you need.
Hope this info helps you solve your problem.
Regards
