Frequently asked questions

What DPV0 and DPV1 support does it have?

This module is a PROFIBUS DP master; it does not support DPV0 or DPV1 slave profiles — the DPV0 and DPV1 fields are marked No for that reason.

What is the power supply requirement?

Requires an external 24 V DC supply (20% tolerance) via a 3-pole terminal block. Power consumption is 2.4 W.

How many DP slaves can it handle?

Can operate up to 32 DP slaves on the bus.
