COMMUNICATION CYCLE
In the communication cycle, you will find configuration parameters for the RS485 Modbus serial port: Baud rate, parity and address.
7.6.1
Baud Rate
The
RHT Transmitter
can be access via a Modbus-RTU network. The baud rate, parity and device address on the network need to be configured
for this. The device responds to the read and write commands in its internal registers according to the specifications set out in this manual (see
chapter on SERIAL COMMUNICATION).
