You have 2 options to get rid of this error: Decrease the need for local data memory to this priority class by distribute your tasks to other priority classes based on the criteria of how fast they should be processed.If you even increase the local memory for one priority class, it means too many extensive FCs/FBs to be called in a same (fast) manner and the next limitation would be an increase in the cycle time of CPU . So, distribute your logic in OB32,33,34,35 that are supported by S7-414H and check the local data memory requirement in cross reference. When distribution is performed, if you need extra local memory data, as cross reference reports add additional in properties of CPU in hw.config I hope this helps, hdhosseini

If you try a high memory value and it still not working, you may check what is consumption of local memory in your FC/FB and try to reduce... What version of PLCSIM you are using?

G_Oliveira Posts: 6 Rating: (0)	hdhosseni, I have a little problem about change the logic, the projet insn't my, it's a other comapany that do it. So, I can't change the logic, I only need to communicate with Elipse SCADA. I thought that maybe I can remove this SF without change the logic. I will talk with the project owner. Thanks for your help.
