2.1 Addressing
2.1.1 DIP switches (Climatix and other controllers)
Use DIP switches for adjustment of the Modbus address and for termination.
● The DIP-switches have priority over register 4x0764 (Modbus address).
● The Modbus address (register 4x0764) is valid as soon as all DIP switches are
on '0'.
● Changes of DIP switches are effective after 5 seconds.
Modbus addressing
The DIP switches allow addresses between 1…247 (Modbus specification).
The following example shows Modbus address '3':
Modbus termination
● The termination is done with 120 Ω + 1nF.
● Even if the addressing is done with "On-event addressing (Climatix controllers)
[➙ 13]", the termination has to be done manually.
