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
