Digital interfaces

Communication with controller KS 800 is possible only via the digital interfaces. Reading process
values, changing set-points or control parameters is always done via these interfaces.
There are two types of interfaces:

8.1

Engineering tool interface

The PC interface is provided on all controller versions. This interface is a special interface using the
ISO 1745 protocol. Access to all controller values is possible using the relevant software, the engi-
neering tool. E.g. for simple applications or test circuits, an individual unit can be configured and the
control loops can be operated normally via this interface.
Connection is to the 4/4 FCC68 data connector (Western telephone connector) via a special
PC adaptor, order no. 9407 998 00001.

8.2

BUS interfaces

This interface is used for connecting the KS 800 to a PLC, a PC or a visualization unit. Dependent
of version, the interface is designed for CANbus, CANbus with DeviceNet-protocoll, Profibus or as
RS 422/485 (see section 2.1). The 9-pole sub-D connector and socket are equivalent. They are
used for "through-connecting" the bus with several connected controllers.
