Developed by Harris (GE Harris), Harris-5000/6000 supports communication
between a SCADA system and RTUs of the same denomination. It has been widely
used in North America and comes in several variants:
- Harris-5000
- Harris-5500
- Harris-6000
The main difference between these versions is the extended address range in
Harris-6000.
Harris-5000/6000 operates in half-duplex mode based on the master/slave
principle.
One master can communicate with up to 63 RTUs, while each RTU only responds to
explicit requests from the master.
Harris-5000/6000 does not support quality identifiers, transmission of time stamps
is however possible.
