  • Simple parameterization via a parameterization tool integrated into STEP 7

Область применения

The CP 440 communications processor is used for high-performance transmission of short message frames via RS 422/RS 485 (X27). This is the preferred method for implementing point-to-point connections.

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

  • SIMATIC S7, SIMATIC S5 programmable logic controllers and third-party controllers
  • Programming devices and PCs
  • Robot controls
  • Scanners, barcode readers
  • Measuring systems
  • Scales

The RS 485 interface supports links to up to 32 partners.

Дизайн

The communications processors have the following mechanical features:

  • Rugged plastic housing
  • LEDs:
    For 'Send', 'Receive” and ”Error”.

The CP 440 can also be used in expansion racks. However, transmission of the C bus signals must be ensured. A table with possible applications can be found under 'Technical specifications'.

Функции

A number of standard protocols are implemented and allow data exchange with a wide variety of nodes:

  • ASCII:
    For connection to third-party systems with simple communication protocols, such as protocols with start and end characters or protocols with block-check characters. The interface's handshake signals can be scanned and controlled via the user program.
  • 3964 (R):
    For connection to Siemens devices or third-party devices by means of the standardized and published Siemens 3964 (R) protocol. Also implemented are a 3964(R) driver with default values and a programmable 3964(R) driver.
Parameterization

Parameterization of the CP 440 communications processor is particularly convenient and simple:

  • The user specifies module characteristics via a parameter assignment tool integrated in STEP 7, such as:
    • Which implemented protocol driver is to be used, or
    • Which driver-specific features are to be utilized
  • Parameterization via CPU:
    Simply connect the programming device to the CPU. The configuration data is filed in a system data block that is saved in the CPU. When a module is replaced, the new module is thus immediately ready for operation.
  • Configuring package (on CD-ROM):
    With electronic manual, parameterization screen forms and standard function block for communication with the CP
