This sample Machine Edition project implements Modbus RTU Master COMMREQs to do the following: 
 configure port for Modbus master, read registers, read output bits, read input bits, 
force (write) output bits, read status, clear status.  Each command except configure port
 is commanded by an %I bit.  The command runs continuously until the %I bit is off.
