Basically, I am programming a PLC that is attached to a series of limit switches and as part of the interrupt service routine in Step 7 I
want to write out from the PLC to the PC serial port a particular string value depending on the limit switch triggered. The serial port is
being polled by a separate program in MATLAB to look for these string values.
