3.11. Connecting The Serial Interface RS 485
An external operating component (DCU 001, DCU 300
or
HPU 001
)
or
an external computer can be connected via the
connection ”RS 485” on the TC 600 with the use of a shielded
8 pole modular connecting cable contained with the delivery.
All units connected to the bus must have differing serial
interface addresses (parameter 797).
The group address of the TC 600 is 960.
Only SELV may be connected to the Serial Inter-
face RS 485.
All switched on remote functions have priority over the serial
interface functions.
Please refer to Operating Instructions
PM 0488 BN for detailed operating
procedures and electrical data in respect of the
Serial Interface RS 485.
Profibus DP Gateway TIC 250 is available (accessory) for
connecting an Electronic Drive Unit TC 600 to a Profibus DP.
Please refer to the respective Operating Instructions
PM 0599 BN for detailed information on the operation of the
TIC 250.

Connecting The RS 485
Connection to a fixed bus system
➡
Connect all units with D+ (pin 5 / RS 485) and D- (pin 7 /
RS 485) to the bus.
➡
The bus must be closed at both ends.
The connections should be made in accordance with the
specification of the Serial Interface RS 485.
