5 Detail description of controllers
5.1 UC20-WL2000-AC
Up to 64 active u-remote modules can be connected via the
u-remote system bus to the UC20-WL2000-AC controller.
The controller has two Ethernet connections for integration
into the existing network architecture or HMI connections.
The integrated engineering tool u-create web can be
launched via the USB service interface or over Ethernet. In
u-create web, the u-control station can be congured and
parametrised and control applications can be programmed
according to IEC61131-3 with the additional programming
language JavaScript by Node-RED.
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.
