Description
© PHOENIX CONTACT 2016-03-14
The RS-485 front module for I/O extension modules allows
Radioline stations to be operated via a 2-wire RS-485 bus
system. The front module can be extended with up to
32 I/O extension modules via the DIN rail connector.
Addressing of the front module and I/O mapping of the
extension modules is carried out quickly and easily using
the thumbwheel on the front. You can therefore distribute
I/O signals in an RS-485 bus system easily, without any
programming or configuration.
Alternatively, you can operate the stations via the Modbus/
RTU protocol and integrate them in any Modbus network.
The front modules can also be connected to a Radioline
wireless master, thereby offering cross-media I/O mapping
between the wireless network and RS-485 bus system.
