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
