Communication
3.4 DPV1
Requirement for using the DPV1 functionality with DP slaves
For DPV1 slaves from other vendors, you will need a GSD file conforming to EN 50170,
revision 3 or later.
Extended functions of DPV1
• Use of any DPV1 slaves from external vendors (in addition to the existing DPV0 and S7
• Selective handling of DPV1-specific interrupt events by new interrupt blocks.
• Reading/writing SFBs that conform to standards to the data record (although this can only
• User-friendly SFB for reading diagnostics.
