An OPC client interface lets you integrate any OPC server, using the Data
Access specification. An offline Importer supports the engineering workflow to
integrate OPC items.
See
OPC Server Integration Guide
(A6V10415483).
An OPC server option provides a freely configurable set of data points for
integration in any enterprise system, using the OPC DA standard. Each data
point (object) is represented by several OPC items, providing the relevant
readable and writable object property information.
See
OPC DA Server Manual
(A6V10415485).
The Desigo CC OPC server is officially tested and certified by the OPC
foundation (https://opcfoundation.org/products/view/251).
OPC Unified Architecture (OPC UA) clients can connect to the Desigo CC OPC
DA server using the OPC DA/UA wrapper, provided with the Desigo CC setup.
The UA wrapper meets the security model of mutual authentication for a
trusted connection between the OPC UA server and the OPC UA client.
See
OPC DA Server Manual
(A6V10415485).
Simple Network Management Protocol (SNMP) is a data communication
protocol for monitoring devices and applications on a network. It is an Ethernet
based protocol for retrieving management data from networked devices, and
exposing this data as properties.
SNMP gives you the capability to monitor a device, e.g., a printer or UPS, which
is not directly configured on a computer, but can be reached through a network
link.
Device monitoring capabilities are provided by device manufacturers via a
Management Information Base (MIB) text file, which describes the structure of
the device management data. MIB files use a hierarchical namespace
containing object identifiers (OID). Each OID identifies a property that can be
read or written via SNMP.
Desigo CC has an SNMP Manager feature for reading and writing information
from SNMP agents.
See
SNMP Application Guide
(A6V10455382).
Using RESTful technology, Desigo CC provides alarm, object and time series
data via web based services for supervising management platforms or other
third-party external applications.
21.2 Integration on automation level
The integration of third-party devices and systems on the automation level is
appropriate when:
Cross-communication to other PX or BACnet devices is needed
System functions (e.g., alarms, trends, schedulers) are needed
The PX Open Platform comprises:
PXC001.D system controller for the integration of KNX, Modbus, M-Bus and
SCL via BACnet/LonTalk
PXC001-E.D system controller for the integration of KNX, Modbus, M-Bus
and SCL via BACnet/IP
PXA40-RS1 and PXA40-RS2 option modules for additional data points
The automation stations have interfaces to RS232, RS485 and KNX.
Xworks Plus (XWP) is used to engineer all solutions. Various compounds and
blocks are available.
The following solutions on the PX Open platform are available:
PX KNX
PX Modbus
PX M-Bus
