6ES7340-1AH02-0AE0 Siemens SIMATIC S7-300 CP 340 Communications Processor Original Brand New

• The economical complete solution for serial communication via point-to-point links.
• 3 versions with different transmission interfaces:
  • RS 232C (V.24)
  • 20 mA (TTY)
  • RS 422/RS 485 (X.27)
• Implemented protocols:
  • ASCII
  • 3964 (R) (not for RS 485)
  • Printer driver
• Simple parameterization via a parameterization tool integrated into STEP 7

The CP 340 communications module is the cost-effective and complete solution for serial communication. It can be used in SIMATIC S7-300 and ET 200M (with S7 as master).

Point-to-point connection is possible to devices including:

• SIMATIC S7 and SIMATIC S5 automation systems and the systems of many other manufacturers
• Printers
• Robot controls
• Modems
• Scanners, bar code readers, etc.

The communications processor is characterized by the following mechanical features:

• Rugged plastic housing
• LEDs:
  For indicating “Send”, “Receive” or “Error”
• Communication interface

It can be supplied in three versions for the following physical transmission characteristics:

• RS 232C (V.24)
• 20 mA (TTY)
• RS 422/RS 485 (X.27)

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

• ASCII:
  For linking to third-party systems using simple communication protocols. e.g., protocols with start and end characters or protocols with block-check characters. The handshake signals of the interface can be scanned and activated from the user program.
• Printer driver:
  For logging process statuses and events to a printer.
• 3964 (R) (not for RS 485):
  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

The CP 340 communications processor is particularly user-friendly and easy to parameterize:

• The user specifies module characteristics via a parameter assignment tool integrated in STEP 7, e.g.:
  • 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 blocks for communication with the CP.
