Remarks
- It starts and initializes the Pipe Network, based on the command specified by cmdID.
- Internally this function calls the Function Block PNCode.
- This is a special function.
- It should only be used in Pipe Network applications that contain FFLD POUs that call PNCode.
- To use this function, Pipe Network must be declared as a global variable in the dictionary.
- Calling this function instead of PNCode in FFLD POUs eliminates this compile error that occurs after modifying the Pipe Network using the Pipe Network editor:
Controller:PLC:Main: NW1(1,14): PNCode: Invalid block height
- The compile error is generated because the number of outputs on PNCode can vary.
- This occurs after modifying the original Pipe Network using the Pipe Network editor.
- The new PNCode Function Block is not automatically updated in any FFLD POUs, reflecting the new outputs.
- Manually update each PNCode function block call in any FFLD POUs to correct this problem.
