3.2.8 DeviceNet module, SK TU3-DEV
DeviceNet is an open communication profile for distributed industrial
automation systems. It is based on the CANbus system.
Up to 64 participants can be linked to one Bus system.
The transfer rate (125. 250. 500 kBit/s) and the Bus addresses are set
using rotary coding switches or the applicable parameters.
Detailed information can be found in the operating instructions

3.2.9 InterBus module, SK TU3-IBS
With InterBus up to 256 participants with different automation devices
can exchange data. PLC's, PC's, operating and monitoring devices can
all communicate via a uniform bus in serial bit mode.
NORDAC frequency inverters are remote bus participants. The data
width is variable (3 words; 5 words), at a baud rate of 500kBit/s
(optional 2Mbit/s). An additional termination resistor is not necessary as
it is already integrated. Addressing is carried out automatically by
means of the physical arrangement of the participants.
An external 24V supply is required for uninterrupted Bus operation.
