Fig. 8: BUS cable (examples)
A BUS cable (6 m with branch)
B BUS cable (1 m)
The BUS cable is connected to the data interface and is used for
linking control units.
The 6 m long BUS cable (Fig. 8/A) is used to link up to 8 control
units.
The operator can use the branch to connect safety edges, sensors,
stop inputs or a further sync BUS cable.
The 1 m long BUS cable (Fig. 8/B) is used to link up to 2 control
units.

If there are more than two connected control units in a sync BUS
system, two terminating resistors are required at the beginning and
end of the BUS system.
The terminating resistor (Fig. 9) is connected directly to the DATA
interface of the first (master) control unit and the last (slave) control
unit.
