Section 12.3: Modbus TCP Slave – PLC Setup and Sequence of
Operations – Version 1.0 and 1.1 Legacy
Note: mCore will not perform calculations unless a License file AND at least 1 Viewer
file is uploaded, set to active, and clicked Store Changes.
This version will work the same way as the older firmware version of mCore running
V.5 or V1.0. The next section uses a different and improved method that requires a
different User Data file.
1. Setup the PLC to write the compressor values to the corresponding registers (40K
Reals/Floats) per the Data Map’s Writes tab.
2. Once all the compressor values are written and you are ready to start the
calculations, write a 1 (40k Real/Float) to either register 400075 or 400273.
3. When calculations are done, mCore will set the force calculations registers back
to zero. When the force calculations register(s) gets put back to a zero, have the
PLC watching for it to turn to zero and have this trigger the PLC to read the new
calculated values.
4. Repeat Steps 1-3 as often as you want to get new calculated values. Typical
calculation time is 500ms or .5s.
