Hello! 

Greetings!

Has anyone here managed to connect the PLC S7 315 ​​2DP (6ES7 315-2AG10- 0AB0) version 2.6 programmed with TIA Portal V14 with the CU320DP V2.5x (6SL3040-0MA00-0AA1) of Sinamics S120 via profibus DP?

I ask because recently a machine arrived at the factory from another city, from another country. The machine was all designed and assembled in Germany, all developed in Simatic Manager V5.5 with STL language and connected with Stater V4.4 for configuring the drives and feeds of the Sinamics S120.

Due to the excess of failures and long downtimes, we decided to reprogram the PLC (the only master in the profibus DP network) to make our lives easier and install an HMI for process vision.

Then I reprogrammed the PLC using TIA Portal V14, inserted the GSD (same model and version of the CU320DP) in the network, but even copying the addresses that were assigned to the drives by the HWConfig of the Simatic Manager sent to the Starter, I don't see the telegrams arrive in Sinamics.

I'm using the WRREC Block (old SFC53) to send the telegram on the network, where the ID is the drive address, the INDEX the profibus address, the LEN the number of words and the record the table. The block cycles but Sinamic ignores the block.

Could someone give me a hint where I went wrong, please? 

Hugs

Leandro Augusto.
