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

• ASCII:
  For communication with third-party systems using simple transmission 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 controlled by means of the user program.
• 3964(R)
  For communication with Siemens devices or third-party components using the standardized, open Siemens protocol 3964(R). A 3964(R) driver with standard values as well as a parameterizable 3964(R) driver are implemented.
• RK 512, for computer communication.
• Use of customized protocols (reloadable drivers).

Parameterization

Parameterization of the CP 341 communications processor is particularly user-friendly and simple:

• Users define the module properties using a parameterization tool integrated in STEP 7, e.g.
  • which implemented protocol driver is to be used, or
  • which driver-specific properties are to be used.
• Parameterization via CPU:
  Simply connect the programming device to the CPU. The configuration data is stored in a system data block that is stored in the CPU.
• Configuration package (on CD):
  with electronic manual, parameterization screen forms and standard function blocks for communication with the CP.

Configuring the drivers

The configuration package for CP 441-2 and CP 341 V4.0 and higher and STEP 7 V4.0 are required to load and configure the drivers.
The drivers are copy-protected by a dongle.
