Functions
These freely programmable automation stations provide the infrastructure for the
provision and processing of system-specific and application-specific functions.
Apart from the freely programmable control functions these units comprise integrated
convenient management functions such as:
•
Alarm management with alarm routing throughout the whole network. Three level
alarm management (simple, basic and enhanced) with safety control transmission
and automatic transmission monitoring
•
Time schedulers
•
Trend functions
•
Remote management functions
•
Access protection for the whole network with individually defined user profiles and
categories
These automation stations are freely programmable with the D-MAP programming
language (follows closely CEN Standard 1131). All function blocks available in libraries
are graphically linked with the plant operating programs.
Communication is via Ethernet with the international standard BACnet protocol.
Both peer-to-peer communications with other automation stations and connections to
the PXM20-E operator units are supported.
The devices communicate via an open LonTalk system in accordance with the inter-
national standard BACnet protocol. Both peer-to-peer communications with other
automation stations and connections to the PXM20 operator units are supported.
The devices communicate via the public telephone network in accordance with the
international standard BACnet protocol.
