3.5.7 DeviceNet, SK TU4-DEV, ...-M12
Up to four connected frequency inverters can be managed by the internal DeviceNet module via DeviceNet
(control, status messages, parameterisation and diagnosis).
• Baud rate: Max. 500 kBaud
• Protocol: AC-Drive and NORD-AC
• 4x digital inputs
• 2x digital outputs
• DIP switches for: addressing, baud rate
• Status LEDs: Module status, module error, bus status, bus
error, Dig.
• Additional LEDs, M12 version: Dig. In 1 - 4, Dig. Out 1 - 2
Control connections SK TU4-DEV(-…)
The double spring terminal block of the BUS -Adapter Unit is colour coded to indicate the three different
potential levels .
A separate voltage source should be used to supply the DOs. However, it is also possible to implement the
supply of the DOs by bridging the 24V o
and GND o with one of the terminals of the system bus level (24V
and GND
). However, in this case it should be noted that this produces an increased risk of errors on the bus
cables.
The sensors and actuators are connected to the terminal block. Alternatively, the SK TU4-DEV-M12 module
enables connection of the digital I/Os via the M12 round plug connectors (Socket, 5-pin, A-coded) on the
front of the module.
Double use of the inputs via the terminal block and
the M12 round plug should be avoided.
