Область применения

The CP 443-5 Basic communications processor is the module required for SIMATIC S7-400 for the PROFIBUS bus system.

It offloads communication tasks from the CPU.

Communications options of the S7-400 through communications modules:

  • FMS communication with PROFIBUS stations through PROFIBUS
  • Communication with programming devices, human machine interface devices
  • Communication with other SIMATIC S7 systems
  • Communication with SIMATIC S5 PLCs

The number of CPs that can be operated depends on the performance range of the CPU and the communication services used.

Дизайн

The CP 443-5 communications processor features all the advantages of the SIMATIC S7-400 design:

  • Compact construction,
    9?pin Sub?D socket for connection to PROFIBUS
  • Single-width module
  • Easy installation,
    the CP 443-5 is mounted on the S7-400 rack and connected to the other modules of the S7-400 by means of the backplane bus. No slot rules apply in this case.
  • User-friendly wiring,
    the Sub-D socket is easily accessible and simple to operate.
  • The CP 443-5 Basic can be operated without a fan. A backup battery or memory module is not required
  • When using SEND/RECEIVE, the number of operable modules depends on the S7-400 CPU used.

Функции

The CP 443-5 Basic provides access to different communication services of the PROFIBUS bus system:

  • PG/OP communication
  • S7 communication (S7 controllers)
  • Open communication (SEND/RECEIVE)
  • PROFIBUS FMS (to IEC 61158/61784)
  • Time synchronization

PG/OP communication

PG/OP communication allows all S7 stations connected to the network to be remotely programmed.

  • S7 routing
    With the aid of routing it is possible to use programming device communication across networks.

S7 communication

S7 communication is used for the coupling

  • between SIMATIC S7 automation systems
  • to programming devices (PG/OP communication)
  • To PCs,
    e.g. with CP 5512, CP 5611 A2, CP 5621 and SOFTNET-PB S7 or CP 5613 A2, CP 5613 FO, CP 5614 A2, CP 5623, CP 5624 and HARDNET-PB S7
  • to HMI devices (OPs).
  • For redundant S7 communication, the CP 443-5 Basic can also be used in SIMATIC H systems.

Open communication (SEND/RECEIVE)

Based on Layer 2 (FDL) of PROFIBUS, the CP 443-5 Basic offers a simple, optimized interface for data communication. This interface offers integrated, high-performance communication between SIMATIC S5, SIMATIC S7 and the PC. It provides the services SDA (PLC/PLC connections) and SDN (Broadcast/Multicast).

The communication partners are the automation systems:

  • SIMATIC S7
    with CP 342-5, CP 343-5, CP 443-5 Extended and Basic
  • SIMATIC S5
    with S5-95U with PROFIBUS interface, S5-115U/H, S5-135U, S5-155U/H with CP 5431 FMS/DP
  • SIMATIC 505
    with CP 5434-FMS
  • PCs
    with CP 5512, CP 5611 A2, CP 5621, CP 5613 A2, CP 5613 FO, CP 5614 A2, CP 5623, CP 5624
  • Non-Siemens systems that are equipped with an FDL interface.

To use SEND/RECEIVE, function calls are required (PLC-SEND/PLC-RECEIVE), which must be linked into the STEP 7 user program.

PROFIBUS FMS

PROFIBUS FMS, according to IEC 61158/61784, permits the transmission of messages via various FMS services:

  • READ, WRITE,
    for read or write access to variables of the communication partner from the user program (by means of a variable index or variable name), for the transfer of its own variable values to the communication partner.
    Partial access to variables is supported. The communication takes place over acyclic connections (master/master, master/slave), over acyclic connections with a slave initiative and cyclic connections (master/slave).

  • INFORMATION REPORT,
    (Report) permits unconfirmed transmission of variables by an FMS server. This job type is used particularly for transmission on broadcast FMS connections.
  • IDENTIFY,
    for requesting the identification features of the communication partner
  • STATUS,
    for requesting the partner status

Time synchronization

The CP 443-5 Basic is capable of forwarding the time of day of the S7-400 CPU to PROFIBUS. Conversely, the CP 443-5 Basic of the S7-400 CPU can make an existing time of day available on the PROFIBUS.

Diagnostics

Extensive diagnostic options are available via STEP 7, including:

  • Status of the CP
  • General diagnostics and statistics functions
  • Connection diagnostics
  • Bus statistics
  • Message buffer

Configuration

STEP 7 V5.1 SP2 or higher is required for configuring the full functional scope of the CP 443-5 Basic. In Version V5 or higher of STEP 7, the configuration data of the CP can also optionally be stored on the CPU and is retained even if there is a power failure. A module can therefore be replaced without having to reload the configuration data from a programming device. The CPU transfers the configuration data to the CP during start-up.

Configuration and programming of all SIMATIC S7 controllers connected to the network is possible over the network.

The function blocks for using the open communication (SEND/RECEIVE) can be found in the SIMATIC NET library following installation of STEP 7.
