The interface of the block was changed.After Savd/Load,this results in an interfacde conflict with the block that reference it .When this block is loaded,the CPU can go into the STOP mode. Contine Save/Load?

STEP7帮助提示是: Correcting the Interfaces in a Function, Function Block, or UDT If you need to correct the interface in an FB, FC, or UDT, proceed as follows to avoid time stamp conflicts: 1.Generate an STL source file from the block you want to change and all directly or indirectly referenced blocks. 2.Save the changes in the source file you generated. 3.Compile the modified source file back into blocks. You can now save/download the interface changes. 请各位高手指点一下,我该怎么修改?
