In the Simatic Manager project, we have two FBs created in the GRAPH language. We have encountered an error during the migration process and I would greatly appreciate your assistance in identifying and resolving the issue. I have attached some snaps of the migration process. Error: SL_CPU315-2DP\FB15 & FB16: Component S7GraphWrapper.dll is not installed or is not functioning correctly. Best Regards, Tech Ahmed Attachment Snap.zip (280 Downloads)

When compiling these two blocks in S7-GRAPH there are some errors "Error >>> The comparator includes a type conflict". It is giving errors on all comparators where one data type is DINT to compare with TIME and the used block is >=D. Please find the attached snap.

However, S7-GRAPH would compile without errors if both operands had the same data type. So you can change the mismatched data type and perform the migration. Afterwards, you can change the data type back because STEP 7 in TIA Portal supports such a comparison. Kind regards Stefan
