ATTENTION
Property damage due to incorrect network
settings.
Incorrect network settings can cause faults in
the IT network!
Consult your network administrator for the
correct network settings for your device.
8.2 RS485 interface
(serial interface)
The RS485 interface for this device is designed
as a 3-pole plug contact and communicates via
the Modbus RTU protocol.
Recommended cable type:
·Unitronic Li2YCY(TP) 2x2x0.22 (Lapp Kabel).
Connection capacity of the terminal:
·0.2 - 1.5 mm 2 (see chap. „18. Technical data“
on page 58)
NOTE
CAT cables are not suitable for the bus wiring!
Use the recommended cable type (see above).
A segment of an RS485 bus structure can
contain up to 32 participants/devices. Use
repeaters to connect segments with more than
32 participants/devices.
To prevent the addition of residual current when
using several devices, mount the data GND as a
functional ground (see fig.)!
The device does not contain an integrated
termination resistor (see chap.„8.4 Termination
resistors“ on page 28).
