Lapmaster Posts: 15 Rating: (0)	Hi Experts, I'm facing problem with D425 2DP/PN, the PLC went to Stop mode. One of our machine is at customer end and suddenly machine was not functioning. The Simotion went to Stop mode. How to put that back to RUN mode? Attached the alarm & drive buffers for your reference. Thanks in advance. -Vignesh ------------------------------------------------------------------------------------------ Split from Why goes Simotion CPU to stop mode? .

Now lock on the details , here you see unit and line where the exception is occured, check this code! Regards Christoph

Division by 0 or something like that. Check the code of the unit which math or numeric operation with which variables you execute and check on the customer site which values are used. Regards Christoph
