Dear Experts and alex, Alex glad to see your problem was solved, hope you can help me with mine, i am trying to use a G120C with profinet and a S7-300 processor (Cp315 2PnDP ), i want to control a pump and send speed reference and start stop commands. i took as reference one post on the Siemens https://support.industry.siemens.com/cs/document/61450312/sinamics-g:-speed-control-of-a-g120-using-s7-300-400-(tia-portal)-with-profinet-profibus-safety-integrated-(via-profisafe)-and-hmi?lc=en-ww Since i've never implemented a drive over PN with a siemens processor. the problem that i have is that when i write some Speed reference to the drive it works for a while, after 1 or 2 minutes, the speed reference goes to 0 even tho im still writing the setpoint( im checking the setpoint on the Micro starter software, there i can see how my setpoint is changed to 0, without me asking for it). i dont know if you could share your configuration so i am able to configure it. i have an OB82 and OB85 (just the blocks, no code in them) for fault diagnostic, but when the reference goes to 0 i have no message of fault or anything, no alarms, just nothing. Every other configuration is just like the one on the example of the link that i posted, Telegram 352, Drive is declared as distributed IO. im doubting about code execution but I ain't sure about that. thanks a lot! ------------------------------------------------------------------------------------------ |
