  • For fast, high-performance serial data exchange via point-to-point connection
  • 2 versions:
    • CP 441-1 with 1 variable interface for easy point-to-point coupling.
    • CP 441-2 with 2 variable interfaces for high-performance point-to-point connection.
  • Plug-in interface modules for different physical transmission properties:
    RS 232C (V.24), 20 mA (TTY) or RS 422/RS 485 (X.27)
  • Implemented protocols: ASCII, 3964 (R), printer driver,
    for CP 441-2 additional RK 512 and Modbus RTU (reloadable)
  • Simple parameter assignment using tool integrated in STEP 7

Область применения

The CP 441 communications processor is used for fast, powerful serial data exchange over point-to-point connections, off-loading the CPU from communications tasks.

Point-to-point connection is possible, for instance, for:

  • SIMATIC S7 and SIMATIC S5 programmable controllers, and systems from many other manufacturers
  • Programming devices and PCs
  • Printers
  • Robot controls
  • Scanners, bar code readers, etc.

The communications processor come in two versions:

  • CP 441-1:
    With one variable interface, for simple and low-cost point-to-point connections.
  • CP 441-2:
    With two variable interfaces, for high-performance point-to-point connections.

Дизайн

The communication modules have the following mechanical features:

  • Rugged plastic enclosure
  • LEDs:
    for displaying 'Send', 'Receive' and 'Error'.
  • 1 (CP 441-1) or 2 (CP 441-2) slots for plug-in interface modules. Interface modules for the physical transmission media RS 232C (V.24), RS 422/485 or 20 mA (TTY) can be plugged into the slots

The CP 441-2 and CP 441-2 can also be operated in expansion racks. However, transmission of the K bus signals must be guaranteed here.

Drivers

Different loadable drivers are available for the CP 441-2:

  • Modbus:
    For communication according to the Modbus protocol with RTU format:
    • Modbus master, master-slave interfacing with SIMATIC S7 as master.
    • Modbus slave, master-slave interfacing with SIMATIC S7 as slave, message frame traffic from slave to slave not possible.

The two serial interfaces of the CP 441-2 can be operated independently of each other with different standard protocols or loadable drivers together with the V.24/TTY/X.27 interface modules.

Функции

User-friendly functions make the communication modules flexible and cost-effective:

  • Different transmission protocols:
    • 3964 (R), for connecting Siemens devices,
    • RK 512, for connecting computers (only for CP 441-2),
    • Printer drivers, for controlling printers,
    • ASCII, for the easy and variable connection of third-party devices,
    • For CP 441-2 additional use of Modbus RTU possible (reloadable drivers)
Parameter assignment

Parameterization of the CP 441-1 and CP 441-2 communication modules is especially user-friendly and simple:

  • STEP 7 tool for communications configuration:
    The user uses the communications configuration to define which protocol driver is to be used or which driver-specific properties are to be used.
  • Parameter assignment via the CPU:
    The PG is simply connected to the CPU. Communication with the CP takes place via the C bus.

The configuration data is saved in a data block, which is saved in the memory card of the CPU. When modules are replaced, the new module is therefore immediately ready for use.

  • Configuration package (on CD):
    With electronic manual and parameterization input screens. As of STEP 7 V11 (TIA Portal), the necessary parameterization input screens are already integrated.
Configuring the drivers

The SIMATIC PtP CP Loadable Drivers Configuration Package and STEP 7 (V5.3 or higher) are required to load and configure the drivers. The drivers are copy-protected by a dongle.
