4.4.2 Binary TCM Protocol C++ Communication Examples
The following 4 example files, CommProtocol.h, CommProtocol.cp, TCM5.h and TCM5.cp would be used
together for proper communication with a TCM3, TCM5 or TCM5L module.
NOTE: The follwing files are not included in the samples code: SystemSenPort.h; Processes.h,
TickGenerator.h.
4.4.2.1 CommProtocol.h File:
#pragma once
#include "SystemSerPort.h"
#include "Processes.h"
//
// This file contains objects used to handle the serial communication with the unit.
Unfortunately, these files are not available as the program was written on a non-PC computer.
The comments in the code should explain what is expected to be sent or received from these
functions so that you can write this section for your specific platform. For example, with the
TickGenerator.h, you would need to write a routing that generates 10msec ticks.

// Process is a base class that provides CommProtocol with cooperative parallel processing. The
Control method will be
// called by a process manager on a continuous basis.
