The system functions govern the general functions of the automation station. These
include the following tasks:
8883Z04E
Operation and display
Communication
Processing
In the VISONIK BPS, the system functions primarily are ensured by their respective
operating system. This operating system works in real time and allows for multi-tasking
(simultaneous processing of different tasks). It is permanently saved in EPROM on the
VISONIK BPS's program card.
The table below contains the system functions that are available in the VISONIK BPS
for the respective tasks:
Task System functions
Operation and
display
−
Selection and display of processing values via keyboard and
LCD display at the VISONIK BPS
−
Execution of manual commands, in accordance with the active
POP Card (Personal Operating Process Card)
−
Operating and display via dial-up communication
Communication Data exchange via the VISONIK BPS interfaces using:
−
directly connected peripheral devices for initialization,
downloading programs, operation and data output
−
I/O modules via the P-bus
−
partner stations on the Building Level Network (peer-to-peer)
−
a superposed management station on the BLN
−
integrated room management systems/third-party systems
−
distributed stations via a modem (dial-up communication)
Processing Processing of functions and links defined in the plant operating
program as per the stored processing rules (DDC standard
functions)
The plant operating program includes project-specific basic, processing, and system
functions for the respective technical installations. This program consists of a
combination of predefined and tested function blocks from program libraries. The
combination is made by using the following software tools:
•
VISOTOOL Autogen or
•
European Tool Set
Free programming by using COLBAS *) is also possible. These tools allow for creating
customized solutions for special applications.
