The new multitalented Ethernet device:
Communications processor CP 343-1 Advanced

With the S7-Advanced communications modules, the advantages that Industrial Ethernet has over the fieldbus can be utilized. It is possible to communicate between the field level and the IT world without intermediary gateways. Thus the Advanced CPs permit a flat communications structure which requires little configuring overhead. In many cases, communication gateways between the field level, MES level and ERP level can be omitted. This reduces the configuring overhead and the number of possible error sources.

Communication services in production
Just like the CP 343-1, the CP 343-1 Advanced can efficiently communicate with the S5, S7, OPC servers or the programming device. Via TCP, the communication can also be programmed and permits the integration of many different systems.
PROFINET
As PROFINET controller, the CP in the machine also controls distributed I/O modules. Modular, object-oriented system concepts are supported by the CP over PROFINET CBA.
IT - Communication
Important information about production data can be sent as e-mail. Via links in the Web browser, for example, Quality Assurance can analyze current data from individual machines on web pages. With the FTP protocol, the controller can retrieve files via the CP direct from a main frame computer or PC for order processing.
Security issue
Despite IT communication, the CP 343-1 Advanced has a high degree of protection against attacks from the network. Continuous security updates are not required. An IP access list protects against access from unauthorized computers. Basic protection using passwords combined with personnel and communication services protects against unauthorized access.
Optimum support of maintenance
Independent of one’s location, maintenance personnel can be informed about disturbances via e-mail. The remote diagnosis is carried out via integrated web pages which indicate the status of the controller. Machine or system malfunctions can be diagnosed online with the Internet browser via user-created web pages. Even the machine documentation can be created as HTML files and stored on the web server of the CP. The module can be replaced without the need for a configuration tool, since the file system of the web server is stored on the plug-in C-Plug.
