VEGACOM 557 Profibus DP 23
4.1 PC/DCS output
Max. 255 PC/DCS outputs are available,
depending on the processing system. The
configuration or parameter setting of the PC/
DCS outputs is done with the adjustment
software VVO or via keyboard (VEGAMET) in
the processing system. Several PC/DCS
outputs can be allocated to each measure-
ment loop. This enables the possibility of
transmitting the measured value, e.g. as
“Percentage value“ and “Scaled“, e.g. in
“Liters“ to the Pr ofibus master.

Configuration of the PC/DCS output via
VVO
A PC/DCS output is automatically allocated to
each measurement loop created in the
processing system. As a standard feature,
the PC/DCS output number is assigned auto-
matically. The next fr ee PC/DCS output
number is always used. If, e.g. the PC/DCS
outputs 3, 4, 5 and 6 are still free, the PC/
DCS output number 3 is automatically allo-
cated to the new measurement loop. Which
output number will be allocated, is shown in
VVO during creation of a new measurement
loop in the window „Create new measurement
loop - Measurement loop designation “. By
pushing the button „ PC/DCS address “, a
new window opens in which the allocation of
the output number can be carried out manu-
ally.
It is possible to allocated another or further
PC/DCS outputs to a measurement loop later
on.
Via the menu items „ Configuration, Measure-
ment loop, Modify “ and the button “PC/DCS
outputs“, you reach the window “PC/DCS
coordination“.
Parameter settings of the PC/DCS out-
put via VVO
The following parameter settings can be
made for the PC/DCS output:
- parameters to be transferred, e.g. percent
- unit in which the parameter should be
transferred, e.g. 0.00 %
- transfer error code in the PC/DCS value
(from VVO 2.60)
- measured value limitation
