Configuration
This section explains how to change Modbus address and analog input configuration between 4-
20mA and V/PT input. In most cases the R560 modules will be delivered pre-configured to fit the
system, but changes in the setup compared to the order may cause a need for change of these
settings.
The ClimaCheck PA Pro III configurator is used to set scale and offset for the analog inputs, to
change the inputs to PT1000 or to configure additional R560 modules. See the PA Pro III hardware
manual for more details.
2.1
Change Modbus address
Modbus address is set with DIP switches marked ADR on the top left side of the unit, see Figure 1.
Address is entered as binary where DIP8 = bit 0, switches increase their bit weight from right to
left. Default address for module 1 is 00010100 (20), module 2 is 00010101 (21) and so on, see
Table 1, Figure 1 and Figure 2 below.
RS485 bus termination is activated with the BUS END switch. The last device in the Modbus chain
should have
BUS END ON,
all other R560 units should be set to
OFF
.
