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 UA server
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).
SNMP
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).
Web services
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
● PX SCL
● PX RS-Bus
● PX Pronto
● PX Open Platform (SDK)
