PMA KS 94 PROFIBUS-DP Quick Start Manual

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.
KS 94 / DP
PROFIBUS-DP option for KS 94
Cyclic transmission of up to
16 input and 16 output values
Free definition of data content
Transmission of process and parameter data
Inputs and outputs as decentral IO
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
55
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.
