3 System overview
Examplearrangementofau-remotestation
The modular u-remote system supports common eldbus
systems and conforms to IEC 61131-2. Each station is
assigned a bus address in the eldbus structure. Only the
coupler is eldbus-specic; the I/O modules are independent
of the eldbus.
Up to 64 active I/O modules can be combined in a u-remote
station. The largest expansion possible depends on the maxi-
mum amount of data transmitted by the selected eldbus, in
particular the conguration, parameter, or process data for
the module types provided.
The following components belong to the u-remote product
series:
– Field-bus coupler (gateway): Head station for converting
the respective fieldbus protocol on the u-remote system
bus
– Active I/O modules:
– Modules with digital input (DI) or digital output (DO)
with 2, 4, 8 or 16 channels
– Modules with analogue input (AI) or analogue output
(AO) with 4 or 8 channels
– Pulse width modulation modules (PWM)
– Digital counter modules (CNT)
– Passive I/O modules (no fieldbus communication)
– 24-V power-feed modules (PF) for input or output cur-
rent
– Potential distribution modules (AUX)
– Empty modules acting as placeholders (ES)
– Mechanical fixing elements
– End bracket
– End plate

“Double-click” installation
The u-remote station modules can be installed quickly and
simply. When attaching the module to the DIN rail, a clear
clicking noise can be heard, which means that the module
has clicked into place. In the second step, which involves
pushing the module being installed together with the neigh-
bouring module, a further clicking noise indicates that the
modules have been correctly connected to each other.
