I use Command: Set Actual Position (49) to Achieve。
There is a problem that i can not Solve。
When the power off，the Position Offset is missing。 when power on the position is different as the Position Offset changing。
how to resolve this problem。
If you change the Position Offset, you must update Flash in order to save the value if power is cycled. The RMC has an Update Flash (110) command that can be used for this.
thank you for your reply.
I modify the Position Offset by siemens cpu by profinet. it’s better than Update Flash (110). Is it?
I think that will work very well. Yes, it may be better than updating flash.
