CP 443-1 OPC UA communications processor

Communications processor for connecting a SIMATIC S7-400 to Industrial Ethernet networks via OPC UA mechanisms.

The CP 443-1 OPC UA supports:

  • PG/OP communication
  • Communication via OPC UA as OPC UA server and/or OPC UA client for exchanging process data (data access)

The CP makes it possible to provide data for, or receive data from, other stations via a standardized OPC UA interface direct from the SIMATIC S7-400 controller. The CP can be used here as an OPC UA server and/or an OPC UA client. Communication as an OPC UA client takes place via user blocks standardized by the PLCopen organization. For more detailed information, see also: http://www.plcopen.org/pages/tc4_communication/index.htm

It can be used in SIMATIC S7-400 H systems as well as in standard SIMATIC S7-400 systems, and for fail-safe applications (PROFIsafe) in connection with an S7-400 F-CPU.

Особенности

  • Open, standardized connection of an S7-400 to HMI/SCADA/MES/ERP systems or third-party PLCs using the OPC UA interface.
  • Investment protection thanks to later connection of existing SIMATIC S7 systems to Industrial Ethernet using the CP 443-1 OPC UA.
  • Secure, protected exchange of OPC UA data via fundamental security functions such as authentication, authorization, encryption and signing of data.
  • Completely flexible for connecting to the most diverse corporate systems using OPC UA as client and server
  • High-speed data transfer thanks to communication via TCP/IP.
  • Relieving the CPU of communications tasks.
  • High plant availability through use in the SIMATIC S7-400 H system
  • Optimum support of maintenance through:
    • Remote programming via WAN or internet
    • Secure web-based diagnostics
    • Monitoring with IT network management tools (SNMP)

Область применения

The CP 443-1 OPC UA is a communication module for connecting the SIMATIC S7-400 to Industrial Ethernet. With its own processor, it relieves the CPU of communications tasks and enables connections via the OPC UA protocol.

The CP 443-1 OPC UA permits communication of the S7-400 with:

  • Programming devices, computers, HMI devices
  • Computer with MES/ERP systems
  • Third-party controllers
  • Host computers
  • SIMATIC systems

Дизайн

The CP 443-1 OPC UA offers all the advantages of the SIMATIC S7-400 system design:

  • Compact design:
    • One RJ45 jack for connecting to Industrial Ethernet, automatic data rate detection using autonegotiation and autocrossover,
      the connection is made via the IE FC RJ45-Plug 180 with 180 °cable outlet or via a standard patch cable.
    • Diagnostics LEDs for indicating the operational and communication status
  • Easy installation: The CP 443-1 OPC UA is mounted on the S7-400 rack and connected to the other modules via the backplane bus. No slot rules apply.
  • The CP 443-1 OPC UA can be operated without a fan
  • In combination with the IM460/461, the CP 443-1 OPC UA can also be used in an expansion rack (ER)
  • The module can be replaced without the need for a programming device

Функции

  • One interface for connecting to Industrial Ethernet with an RJ45 connection at 10/100/1000 Mbps full/half duplex with autonegotiation and autocrossover functionality
  • Supported communication services on this interface:
    • As OPC UA server: Read/write access for data exchange (DA), access via subscriptions
    • As OPC UA client: Read/write access for data exchange (DA). Communication via standardized function blocks in accordance with PLCopen
    • PG communication for configuring the CP, cross-network through S7 routing
    • Time-of-day forwarding to the CPU as NTP time client (optionally secure NTP)
    • Module replacement without programming device: All configuration information can be stored on the CPU
    • The CP can operate simultaneously as an OPC UA server and OPC UA client. For corresponding restrictions of the quantity structure, see the manual.
  • Diagnostics and network management:
    • With https via web browser.
    • Standard and extended diagnostics in STEP 7 V5.5/STEP 7 Professional (TIA Portal) V14
    • Integration into network management systems through support for SNMP V1 or SNMP V3
  • Security mechanisms:
    • Access to the data using fundamental OPC UA security functions (authentication by certificate, encryption, and data signing)
    • Secure network management integration (SNMPv3)
    • Secure time-of-day transfer (NTP-secured)
    • Secure firmware updating
    • Secure web server communication (HTTPS)
    • Traceability by means of data logging on the basis of standard IT mechanisms (syslog)
    • Counterfeit detection
  • Configuring:
    • Configuring is performed using Step 7 V5.5 SP4 incl. HF 8 and HSP. The security functions are configured using the Security Configuration Tool (SCT) V4.2 and higher
    • It will be possible to configure the CP including the security functions in STEP 7 Professional (TIA Portal) V14 and higher

Интеграция

The aim is data exchange between a SIMATIC S7-400 and 3rd party systems via a standardized interface. As an OPC UA server, the CP uses OPC UA mechanisms to provide data in a standardized and secure form for linking to an OPC UA-capable HMI, SCADA or database system as a client.

Data exchange with HMI/SCADA/MES/ERP systems from various manufacturers

As an OPC UA server, the communications processor provides data in a standardized form for exchange with a third-party controller. At the same time, the CP can retrieve data from another OPC UA server as an OPC UA client by programming the necessary blocks.

Vendor-neutral controller-to-controller communication
