5.3 C
OMMUNICATION WITH INTERFACE DIRECTLY THROUGH
RS232
Mostly used by PLC‐equipment or special PC‐applications (e.g. Hyperterminal).
You have to write your own communication routines for operating the FLOW‐BUS system by host computer.
The protocol for the communication between the modules is described in a PDF‐file doc.nr. 9.17.027.
For an RS232‐interface module messages will be send by means of ASCII‐strings (or binary).
Advantage:
Simple, straight forward, less overhead
Disadvantage:
Knowledge needed from FLOW‐BUS system about parameters, processes, nodes etc.
See document 9.17.027 for a more information.
