HYGROPHIL® F 5673 Operating manual, Software version 1.8.x, 387896MDHEN(14.06.2013)
The MODBUS slave address has a range from 1 to 247 and could be easily
changed by means of the application software. On the same way the baud
rate (1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200) and the inter-
face’s parity (even, odd, none) can be changed (see section 5.6.7).
The HYGROPHIL
®
F 5673 MODBUS supports function codes „ 01

Read
single coils “ and „ 03

Read multiple holding registers “
Function code
„01“ supplies the master system with the data listed in
Table 1.
