Optimising _STD_CM_AI

Method

  1. Added UDTs _STD_AI_Ctrl, _STD_AI_Par and _STD_AI_Stat to Project Library > Types.
  2. Versioned Originals as V0.0.1
  3. Edited the above UDTs employing arrays and positioned the bits of each boolean array, so that when the optimised DB is transferred to non-optimised DB the bit will be in the write absolute address for the SCADA's DA server.
  4. Re-defined all usage of M bit memory within the FB to use the Input or InOut block interface. all prefixed with "system" Need to replace global memory bit tags with Global DB tags.
  5. _STD_CM_AI compiled and copied to Project Library > Types
