Service Network and Alarm
UA
D variants C, which are equipped with communication electronics and connector could be
connected to a Service Network. The Service Network is a communication protocol used in
UA
D and other compressed air equipment that allow a remote supervision. Work data could
be regularly read out of the device with a network or they could be read by a data logger.
At the same time, the Service Network could also serve as display and keypad for setting
UA
D’s parameters at commissioning.
The Service network consists of two devices. These are a slave device which is
UA
D and a
master device. The master device could be a Service Network Reader SN-10.200. It’s a
handheld device that allows user to send command messages manually. It also comprises a
display where answer to command are read. In the table in next page, command message
codes specific to
UA
D are described. There, we see which work data are collected, which
parameters could be set and which remote commands are available in
UA
D.
More detailed description of Service Network Protocol could be found in document
SN-02.000, Service Network Protocol.
An alarm output is included in the service network. Nevertheless, it may be used to signal
alarm condition without being connected to service network. The alarm/warning output is
an open collector output and it shares its GND with serial communication of Service
Network. The output is in high impedance state during alarm. When
UA
D operates normally,
the output is in low impedance state.
