Landis & Staefa Division Function DPC 2-73
2.10 DPC Data Processing Communication
The name DATA PROCESSING refers to a VISONIK software package which allows
the following functions:
•
Data collection and storing
•
Data presentation (using tables and graphs)
There are three main Functions associated with DATA PROCESSING:
•
DPO
Data Processing Operations
•
DPC
Data Processing Communication
•
DPP
Data Processing Presentation
These main functions display to some degree the same fundamental structure. The DAP
function is advantageously suitable for configurations, while DPP is suitable as a user-
oriented function for presentation.

Protocol).
The data exported from the DCS can be displayed on a terminal using the DPC,EXP
function.
