Hello friends, I have a Sinamics S150 and a PCS7V6.0. The issue here is the profibus communication between them. In the manual of the S150 it shows that P0922 must be in value 352 for profibus for the vector set paramerter. I set for the CU parameter P0922 >390 and for the A_INF>370. You could see this in the Drive set picture attached. For the hardware configuration in PLC I set the same structure for for inputs and outpus, You could see this in the PLC picture attached. Even though the DP led in the CU320 indicates profibus communication is OK, there is no positive response in the data that I send to the drive and viceversa. Could anyone has made this type of communication? Anyone know what I'm doing wrong? Thanks for your help Attachmentprofibus.zip (422 Downloads) |

Hello Luis; Yesterday I prepared a reply to another poster on my experience using Profibus-DP and a Simanics G150 with a 3rd party master. If it can help, you might look at it here. Rehards, Daniel Chartier |

Hello Luis; I was trying to locate some documentation on the S150, strangelyI cannot seem to find any hits for manuals either on the Siemens website of the web. Do you have anything that could explain in detail the parameters you are using to setup communications on your S150? One detail from your earlier postsurprises me: you state that parameter"G150 only has one parameter P0922; S150 has three parameters P0922 that are supposed to be reflected in the hardware configuration of the PLC". Do you mean P0922 can only have one value in the G150, and various in the S150? If you look in this postyou will see in the Sinamics G150 telegram attachment (extracted from the manual I proposed to you earlier) that there are actually 5 different telegrams available for the G150; but only one can run at any time. When you select one, you must adjustthe input/output area of the slave in the PLC hardware configuration so you can match it to theselected telegram requirements. Ifeel that your problem resides here:only one telegram should be selected in your configuration.To test your setup, select only one object for the S150 drive youare setting up, start maybe with the simplest telegram that will give you both a control word and a speed reference word, telegram390 (2 W OUT, 2W IN) and set in the PLC configurationonly the corresponding module (Telegram 390, PZD 2/2). Compile, download and try it out. If it solves your problem, then select the telegram type you require and set it up in the drive and the PLC accordingly. Keep us informed, Daniel Chartier |
