8.3 Modbus/RTU slave (I/O-to-serial)
You can operate every Radioline station as a Modbus/RTU
slave. Simply set the Modbus/RTU address (slave ID) using
the yellow thumbwheel.
The internal Modbus register addresses of an RS-485
station are identical to the known register addresses in the
Radioline wireless network (PLC/Modbus/RTU mode).
Figure 12 Modbus/RTU slave
– Operation as a bus coupler for Modbus/RTU with
Radioline extension modules
– Integration in existing Modbus networks
– As a Modbus to any master
–Up to 98stations per Modbus network
– Fast startup via Plug and Play
– Default setting of the RS-485 interface: 19.2/8/E/1
8.4 Wireless system and RS-485 stations at a
Modbus master (I/O-to-serial)
If you operate a Radioline wireless network in PLC/Modbus/
RTU mode, the entire wireless network acts like a single
Modbus/RTU slave. At the wireless master, you can read or
write the I/O signals of all wireless stations from the Modbus
table. Set the Modbus address (slave ID) of the wireless
master when configuring the wireless network via the
PSI-CONF software.
You can extend this wireless network with RS-485 stations
and operate them together at any Modbus master. All
devices in the RS-485 network are then standard Modbus/
RTU slaves. The Modbus address of the RS-485 stations
can be set directly at the yellow thumbwheel. The RS-485
station automatically detects the protocol of the master.
The Radioline wireless network and the RS-485 stations are
two independent systems. The RAD ID addresses can
therefore be repeated in another system.

stations at a Modbus master (I/O-to-serial)

868MHz, 900MHz)
