5.3 UC20-SL2000-EC
Up to 64 active u-remote modules can be connected via the
u-remote system bus to the UC20-SL2000-EC controller. The
controller has two Ethernet connections for integration into
the existing network architecture or HMI connections.
The controller can be congured as a EtherCAT master.
The u-control station can be congured and parametrised
and controlling applications can be programmed using the
engineering tool u-create studio (according to IEC61131-3,
additional programming languages: C and C++)
The station’s main power supply is integrated into the con-
troller. Power is supplied via two 4-pole connectors, separat-
ed into the input and output current paths.
