3.1.10 InterBus module
(SK TU1-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.
Detailed information can be found in the operating instructions BU 0070, or contact the supplier
of the frequency inverter.
3.1.11 AS interface
(SK TU1-AS1)
The Actuator-Sensor-Interface (AS interface) is a bus system for the simple field bus level. The
transmission principle is a single master system with cyclical polling. A maximum of 31 slaves
(or 62 A/B slaves) can be operated on an up to 100m long unshielded two-wire cable in any
network structure (tree/line/star). The AS interface cable (yellow) transmits data and energy
while a second two-wire cable can be used for a small auxiliary voltage (24V). Addressing is
implemented via the master, which can also provide other management functions, or via a
separate addressing device. The 4 bit reference data (per direction) are cyclically transmitted
with an effective error protection at a maximum cycle time of 5ms.
Detailed information can be found in the operating instructions BU 0090, or contact the supplier
of the frequency inverter.
The SK 700 E supports the AS interface technology unit from software version 3.1 Rev. 1
(P707 / P742).
