Inputs IN1...IN16
The data to be read from the KS 94 can
be defined by means of the Engineering
Tool ET/KS 94 (Version 4.0 upwards).
It is possible to access all signals and pa-
rameters (
ð
Fig.4).
Outputs OUT1...OUT16
The data to be transmitted to the KS 94
can be defined by means of the Engi-
neering Tool ET/KS 94 (Version 4.0
upwards). It is possible to access all sig-
nals and parameters (
ð
Fig.4).
FUNCTIONS
Enabling the controller outputs
The control word allows you to en-
able/disable the digital controller outputs.
De-centralized I/O
All inputs and outputs of the KS 94 are
directly accessible via the I/O memory
area. In this way it is possible to make
use of additional input/output functions
apart from the control function. Analog
values are transmitted in the scaled for-
mat.
Input forcing
All physical inputs can be overwritten via
the PROFIBUS-DP. In this way it is pos-
sible e.g. to define individual elements of
a multi-element control loop via the bus,
or to let the PLC compute corrections for
process value/set-point.
Back-up controller mode
During “normal” operation, the control
output is computed by the master. The
KS 94 is used to measure the process
values, to generate the control output
signal, and for display.
If the master or the bus communication
should fail, the KS 94 takes over auto-
matically and bumplessly.
CONNECTION
AMP flat-pin terminals 1 x 6,3 mm or
2 x 2,8 mm.
By needs of an adapter (
ð
Accessories)
Sub-D connectors or screw terminals
can be used.
