Hello Master; As TechTeam says, this information can only be provided by Schneider. In their manual for the ATV61/71 DPV1, here is what they have to say about PPOs and Profidrive: Altivar ATV61/71 Profibus DPV1 manual PPO cyclic frames contain the periodic variables that are used for 2 types of service: - I/O exchanges (PZD) - Aperiodic exchanges (PKW) for parameter setting, configuration and diagnostics PKW aperiodic exchanges are included in the cyclic frames and do not require special frames. An aperiodic exchange is used to read or write a parameter. The Altivar 61 / 71 PKW service does not conform to Profidrive. On page 31 the manual gives an example of DPV1 (acyclic) exchanges using Siemens SFC58 ("WR_REC") and SFC59 ("RD_REC") to access the PPO values. Attached you will find a printoff of the descriptions of SFC58/59 , from the System and Standard Functions manual you can locate on the Product support pages (use the Search box at the right of this page). Hope this helps, Daniel Chartier AttachmentSFC58 SFC59.pdf (84 Downloads) |
