Supporting Modbus communication on multiple channels

 

MSPL-C supports simultaneous Modbus communication on multiple channels.

This is achieved by dedicating a set of all global variables to each communication channel.

Each channel now operates upon its own private dataset. In effect the library can be used to create virtual Modbus devices.

The macro MAX_NETWORKS is used to set the maximum number of channels required in the implementation.

Set this at compile time because the library uses static memory allocation.
