DESCRIPTION
The PROFIBUS-DP option enables the
KS 94 to be connected to PROFIBUS-DP
networks. This allows de-centralized and
independent industrial and process con-
trollers to be integrated into PLC or PC
systems. The PLC/IPC transfers
set-points and control information to the
KS 94, and polls process values cycli-
cally.
All control functions and the associated
scaling and monitoring tasks are exe-
cuted independently. This ensures high
process safety together with short times
for engineering and commissioning.
DISPLAY AND OPERATION
Via its “day & night” display, the KS 94
shows all process data locally and easily
readable. If required, one line of the dis-
play can be used to show a
freely-definable message.
Furthermore, the controller can be
switched to local operation, e.g. for com-
missioning the control loop without any
previous programming of the PLC or the
supervisory system. In addition, the En-
gineering Tool ET/KS 94 is available as a
useful device. It is connected via a
front-panel socket of the KS 94, and
serves for configuration, parameter set-
ting, and operation of the controller.
The standard graphical trend display al-
lows a qualitative evaluation of the
control results.
DE-CENTRALIZED I/O
Apart from the control function of the
KS 94, it is possible to access all inputs
and outputs directly. In this way, all the
controller’s I/O are also available to the
PLC/IPC.
The basic functions of the KS 94 / DP,
such as inputs/outputs, control
functions, etc. are described in the data
sheet (9498 737 28213) for the KS 94.
Technical data
According to EN 50170 Vol. 2
Reading and writing of all process data,
parameters and configuration data.
DATA FORMAT
Real values such as set-points and pro-
cess data are transmitted in the IEEE
format (REAL) or in the 16-bit fiexed
point format (FIX) with one digit behind
the decimal point (configurable).
PARAMETER CHANNEL
Process data and selected parameter
data are written and read cyclically. All
process-, parameter- and configuration
can be transmitted via parameter chan-
nel. These data are transmitted over
several cycles on request.
