4 Modbus
The EasyTronic EC can be integrated into the building management system via
Modbus RTU. The Modbus slave protocol is implemented in the controller. It uses
an RS485 interface for communication with a Modbus master.
The parameters are accessible as holding registers. Read and write operations
must be carried out with the appropriate function codes (FC 03 / 06 / 16).
Up to 125 variables can be read in one operation. Depending on the baud rate,
select a suitable timeout between the read operations:
Baud rate 38400 ................ 1.0 s
Baud rate 19200 / 9600 ..... 1.5 s
Baud rate 4800 / 2400 ..... 2.0 s
