3.1.4 RS 232 Box
(SK TU1-RS2)
The RS 232 technology unit enables simple connection (cable: RS 232,
P. No. 78910030) from a NORDAC SK 700E to a PC with serial interface.
Communication between PC and frequency inverter can be
achieved using the NORD CON Software (Windows).
Note: When using a standard I/O (SK CU1-STD Chap.
3.2.2), the RS485 termination resistor should be switched off
to prevent possible communication problems.
The connected inverter can be controlled and parameterised
via this interface. This allows a simple functional test of the
inverter to be implemented and, following successful
parameterisation, the data set can be saved as a file.

3.1.5 CANbus module (SK TU1-CAN)
The CANbus interface on the NORDAC frequency inverter enables parameterisation and control
of the device as per the CAN specifications 2.0A and 2.0B. Up to 512 participants can be
addressed on a single Bus. A termination resistor is integrated and can be switched on.
The transfer rate can be set between 10kBaud and
500kBaud.
The collision and error recognition integrated in the CANbus
protocol enables maximum bus usage and data security.
Detailed information can be found in the operating
instructions BU 0060, or contact the supplier of the frequency
inverter.

3.1.6 Profibus module
(SK TU1-PBR)
A large number of different automation devices can exchange data using Profibus. PLC's, PC's,
operating and monitoring devices can all communicate via a uniform bus in serial bit mode.
Data exchange is specified in DIN 19245 Part 1 and 2 and application-specific upgrades in Part 3
of this standard. Within the European field bus
standardisation process, Profibus is integrated into the
European field bus standard pr EN 50170.
The termination resistor for the last bus participant is
located in the Profibus standard plug.
Detailed information can be found in the operating
instructions BU 0020 or contact the supplier of the
frequency inverter.
