Hello; please help me We're trying to replace old VFD Simouvert Master-drive with new Sinamics G120 and keeping the same hardware and software communication with plc S7-400 which is PROFIBUS, We found in Hardware configuration of Step7 that the old masterdrive use PKW to send commands and receive status words instead of PZD but only the reference and speed feedback used by PZD as it is shown in attachement the problem is when we tried to configure Sinamics G120 with Starter, We can choose telegram containing both PKW and PZD, but we can only configure PZD for command and status and feedback; I have two questions: 1)Is it possibly to send commands and receive status words with PKW???????????? Because as I know PKW is only for changing parameter (voltage current frequency..... etc.) and PZD is for send command and control and receive feedback and status and alarms 2) Is it possibly to change telegrams PKW from the original plc program of HW to a standard PZD containing same amount of bytes and same addressing and use it in place of the telegrams PKW of the old masterdrive ; Or if ithere is a method to converting from PKW to PZD
considering that the programs use SFCs 14 of 15 to read and write data from DP slave this is an attachment of a hardware configuration and starter interface AttachmentDocs.zip (510 Downloads) |

Closed cause question posted twice. The second thread with the subject Converting from PKW to PZD on Masterdrive to G120 - how possibly could share command and status in right way? is published within the conference SINAMICS G. Best regards, |
