Hi, I’m trying to configure control of extended safety function from F-CPU PLC with SIMOTION D445-2 via PROFIsafe on PROFIBUS. I’m using http://support.automation.siemens.com/WW/view/en/36489289 document to guide me through configuration process, and it explains it very well. In example we have 2 axis configured, in my project I have 20 axis. I’m stuck at adding axis in the configuration when adding 16th axis I get following message “The allowed number of 32 master/slave rows has been exceeded in row 33. Do you want to edit row 33 now?”. It seems that each axis adds two rows to communication. I can’t add safety communication to another axis. Is there a limit of axis I can transfer this data with? Is it possible to compact those rows into single one? I tried to add another configured station C2xx/P3xx/D4xxISlave object to the hw config but I can’t get it coupled with D445-2. I think it's general limit of the rows that is possible to define in communication, not necessarily applies only to safety data exchange. |

Hello, Do you use external Control Units or do you use CX32 for the 20 axis? There is a known limitation using Simotion with external CUs and Profibus. You can configure only 16 axis with profisafe on one DP connector of the Simotion. If you use both DP connector then you can connect 32 axis with profisafe and profibus. |
