6.13.4. Using the GFC7000E with a Hessen Protocol Network
6.13.4.1. General Overview of Hessen Protocol
The Hessen protocol is a multidrop protocol, in which several remote instruments are connected
via a common communications channel to a host computer. The remote instruments are regarded
as slaves of the host computer. The remote instruments are unaware that they are connected to
a multidrop bus and never initiate Hessen protocol messages. They only respond to commands
from the host computer and only when they receive a command containing their own unique ID
number.
