Hi, I never worked myself with the DCP but I can imagine your problem. The thing is that DCP supports only "free telegrams" - but it still wants to have the first PZD as STW1 (control word 1) according to PROFIdrive profile. In STW1 there is the most important bit to create the cyclic communication between DCP and PLC -> it is Bit 10: Control by PLC. As long as this bit is not connected and not fed with a "1" signal by the PLC the drive will not communicate cyclically with the PLC. So I checked the operating instructions and found the following: - check out chapter 7.4.3 (communication) - in chapter 7.4.3.2 you can see how STW1 is structured I guess you have to create all the bit connections for STW1 yourself manually in STARTER. If you have done so, you need to send a "1" signal firstly from your PLC to Bit10 in PZD1 - then the drive will receive your PLC commands. Here the mentioned manual: https://support.industry.siemens.com/cs/de/en/view/109773591 |
