For fast, high-performance serial data exchange via point-to-point connection
2 versions:
- CP 441-1 with 1 variable interface for easy point-to-point coupling.
- CP 441-2 with 2 variable interfaces for high-performance point-to-point connection.
Plug-in interface modules for different physical transmission properties:
RS 232C (V.24), 20 mA (TTY) or RS 422/RS 485 (X.27)
Implemented protocols: ASCII, 3964 (R), printer driver;
for CP 441-2 additional RK 512 and Modbus RTU (reloadable)
Simple parameter assignment using tool integrated in STEP 7

Область применения

The CP 441 communications processor is used for fast, powerful serial data exchange over point-to-point connections, off-loading the CPU from communications tasks.

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

SIMATIC S7 and SIMATIC S5 programmable controllers, and systems from many other manufacturers
Programming devices and PCs
Printers
Robot controls
Scanners, bar code readers, etc.

The communications processor come in two versions:

CP 441-1:
With one variable interface, for simple and low-cost point-to-point connections.
CP 441-2:
With two variable interfaces, for high-performance point-to-point connections.

Дизайн

The communication modules have the following mechanical features:

Rugged plastic enclosure
LEDs:
for displaying "Send", "Receive" and "Error".
1 (CP 441-1) or 2 (CP 441-2) slots for plug-in interface modules. Interface modules for the physical transmission media RS 232C (V.24), RS 422/485 or 20 mA (TTY) can be plugged into the slots

The CP 441-2 and CP 441-2 can also be operated in expansion racks. However, transmission of the K bus signals must be guaranteed here.

Drivers

Different loadable drivers are available for the CP 441-2:

Modbus:
For communication according to the Modbus protocol with RTU format:
- Modbus master; master-slave interfacing with SIMATIC S7 as master.
- Modbus slave; master-slave interfacing with SIMATIC S7 as slave, message frame traffic from slave to slave not possible.

The two serial interfaces of the CP 441-2 can be operated independently of each other with different standard protocols or loadable drivers together with the V.24/TTY/X.27 interface modules.

Функции

User-friendly functions make the communication modules flexible and cost-effective:

Different transmission protocols:
- 3964 (R), for connecting Siemens devices;
- RK 512, for connecting computers (only for CP 441-2);
- Printer drivers, for controlling printers;
- ASCII, for the easy and variable connection of third-party devices;
- For CP 441-2 additional use of Modbus RTU possible (reloadable drivers)

Parameter assignment

Parameterization of the CP 441-1 and CP 441-2 communication modules is especially user-friendly and simple:

STEP 7 tool for communications configuration:
The user uses the communications configuration to define which protocol driver is to be used or which driver-specific properties are to be used.
Parameter assignment via the CPU:
The PG is simply connected to the CPU. Communication with the CP takes place via the C bus.

The configuration data is saved in a data block, which is saved in the memory card of the CPU. When modules are replaced, the new module is therefore immediately ready for use.

Configuration package (on CD):
With electronic manual and parameterization input screens. As of STEP 7 V11 (TIA Portal), the necessary parameterization input screens are already integrated.

Configuring the drivers

The SIMATIC PtP CP Loadable Drivers Configuration Package and STEP 7 (V5.3 or higher) are required to load and configure the drivers. The drivers are copy-protected by a dongle.
