8 Digital interfaces
The only possibility to communicate with controller KS 816 is via the digital interfa-
ces. Process value read out as well as set-point or control parameter changing are
via these interfaces.
The two interface types are:
8.1 Engineering tool interface
The PC interface is provided on all instrument versions. It is a special interface ac-
cording to the ISO 1745 protocol. The relevant software, i.e. the engineering tool,
provides access to all controller values.
E.g. for uncomplicated applications or tests, configuring an individual unit and ope-
rating the control loops normally are possible via this interface.
Connection is at 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 816 to a PLC, a PC or a visualization
unit. Dependent of instrument version, it is used for CANbus, Profibus or as
RS 422/485 (see section 2.1).
The 9-pole sub-D connector and the socket are equivalent. They are used for "ma-
king a loop" through the bus with several connected units.
