SX OPEN V3

Integration of 3

party devices and subsystems into Desigo system

• Software-based integration platform for to connect third-party systems,

including OPC systems, to a BACnet network e.g. Desigo system

• SX Open provides 1..n free configurable BACnet Server,1 BACnet

TrendServer and 1 BACnet Client

• SX OPC client as a predefined application for 3

party integration via a

standardized OPC interface

• SX API Base for individual development of specific Subsystem 3

Clients

for systems, protocols or other drivers

Functions

SX Open is a configurable 3

party system – BACnet/IP gateway. Using this gate-

way, both Desigo PX automation stations (peer-to-peer) and the Desigo Insight

management station have access to integrated (3

party) data points over the IP

network. It is possible to define BACnet servers to map 3

party datapoints on

BACnet objects including alarming (e.g. High/Low Limits) and processing like,

trend logging and time scheduling. SX OPEN is ideal for the integration of any size

of data points.

SX OPC is a predefined application to map third-party device or system values

available via an OPC interface to the equivalent BACnet objects and their proper-

ties.

Mapping signals and functions Mapping works in both directions, i.e. commands can flow from BACnet to OPC and vice versa. To map the OPC items to BACnet objects/BACnet properties an Excel table must be configured. A special characteristic is that the OPC values can be manipulated by means of function blocks before mapping to BACnet. This can be used for data conversion (signal mapping) or for value calculation (function mapping).

Hardware A standard off-the-shelf PC can be used as hardware platform. Though, for installation into a control panel a model suitable for industrial applications, in the form of an IPC (Industrial PC), is recommended. The selected PC configuration has a substantial influence on the performance of SX OPEN, which basically depends on the amount of data, the time taken to react rd to changes in the data, and other installed software, such as the (3 party) OPC server.
