"Modbus RTU" implementation
This chapter contains general information on the implementation of
the metering pump gamma/ X GMXa into the serial communication
protocol of the Modbus RTU.
The metering pump gamma/ X GMXa acts as a slave (Device 1).
Communication between the metering pump gamma/ X GMXa
(Device 1) and external masters (Device 0) is possible, including a
PLC Programmable Logic Controller.
