Function Blocks
CommunicationChannel
The CommunicationChannel function block is designed to manage an input stream of data from either a serial or
TCP socket communication interface. It collects portions of data from Y_ReadDevice each time that function’s
Done output goes high, and add it to a circular buffer for further analysis. The CommConfig structure must be
initialized by the user to configure the necessary communication parameters.
Parameters
