Hello Forum, I am using a Siemens 1500 PLC and a Vacon NXP Drive. I already monitor and control the drive for Process Data using Fieldbus. In addition to that, now I want to read and write basic parameters of the Drive like ID101 Min. Frequency, ID102 Max. Frequency etc. I am using Profinet communication and a OPT-CP card is installed in the drive. In the Manual for OPTCP, it mentions I need to use RDREC and WRREC to read and write Data Records to the Drive. The starting index is mentioned as 16#B02F which in INT format is 45103. Also, the hardware ID in my project for the Standard Telegram is 264. I am trying to read data first using RDREC but I get the error that is shown below. "80 B5" which mean DP slave/module not ready as per "Help". |

Hallo, Here is the manual for SINAMICS G120. After I saw the dataset is B02F for PROFINET, I assume your dive follows the PROFIdrive specification, so the manual should be valid for your drive too. https://support.industry.siemens.com/cs/ww/en/view/109757336/73504580235
The WRREC and RDREC just transfer the dataset without knowing what's inside. So if they show the transfer is finished, this means the only the transfer of the data set is ok. So sending the request 05 01 01 01 10 01 27 11 should request the reading the value from p10001. Sending the request 05 02 01 01 10 01 27 11 00 65 should write the value 101 in parameter p10001. In the attachment you see the request to read parameters p1120, p1121 and p945 from a SINAMICS drive. And the answer to it. AttachmentreadParameter.pdf (180 Downloads) |
