I'm not sure I understand what you're asking, but I don't believe a function block with this behavior exists in the default libraries. I think the best solution would be using multiple and/or blocks or make your own function block.

Go to Online>Communication Parameters...>Gateway>TCP/IP> Click on "New..." and reestablish your connections with whatever IP address and set up information you have. Bypass whatever is necessary as you may have to redownload to the PLC.

Maybe it is better to use Interfaces to access the objects instead of pointers. But besides that, is "read_obj_ptr" a method? If yes, you need to call it, so add brackets behind the method call: read_obj_ptr();

Hi tommyk-mar, do you call SMC_SmoothPath after SMC_NCIntepreter? Both G51 in the G-Code and the function block call are needed. You can see how this can be done in this example: https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_example_cnc_3.html Best regarsd, Georg

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
