6ES7340-1BH02-0AE0 Siemens SIMATIC S7-300 Communications Processor CP 340 Original Brand New

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
