Multi-Temperature-Controller KS 800

8 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.
