3.5.5 PROFIBUS DP, SK TU4-PBR, ...-M12
Up to four connected frequency inverters can be managed by the external PROFIBUS DP module (control,
status messages, parameterisation and diagnosis).
• Baud rate: max. 12 MBaud
• Protocol: DPV 0 and DPV 1
• 4x digital inputs
• 2x digital outputs
• Automatic detection: PPO type, baud rate
• DIP switches for: addressing, bus termination
• 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-PBR(- …)
The double spring terminal block of the BUS -Adapter Unit is colour coded to indicate the three different
potential levels .
The field bus level is supplied with 24VDC from the system bus level via a DC/DC converter. Therefore
terminals 1/2 are at the same potential as e.g terminal 11. As the DC/DC converter is in the bus module,
there is only a connection between terminals 1/2 and e.g. 11 if the bus module and the connection unit are
screwed together.
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 2 and 0V 2 with one of the terminals of the system bus level (24V and
0V). 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-PBR-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.
