SIMATIC-300: The modular controller for innovative system solutions in the manufacturing industry


The connection of SIMATIC S7-300 controllers via communications processors permits the direct integration of the controllers into Industrial Ethernet. The communications processors have multi-protocol capability and support the following protocols:
- PG/OP communication
- S7 communication
- open communication (SEND/RECEIVE)
- PROFINET communication
- IT communication

CP 343-1 Lean: Even connects small applications to Industrial Ethernet
The low-cost connection for programming devices and HMI devices, as well as for communication between S7 controllers.

CP 343-1: The well-proven, rugged and secure standard version
The efficient, reliable, and rugged communications processor that connects the S7-300 via Industrial Ethernet to the programming device, the HMI application or device, S5 and S7 controllers, as well as SINUMERIK powerline. As controller for the connection of PROFINET IO components.

CP 343-1 Advanced: From PROFINET to IT communication
In addition to the functionality of the CP 343-1, the CP 343-1 Advanced offers e-mail functions, http-based diagnostics and user-created web pages and thus optimally supports maintenance and quality assurance. The Internet functions, such as the FTP Client or JAVA, even permit the direct connection to the ERP level without the need for additional gateways. Therefore, for the S7-300, this CP is the bridge between the field level over PROFINET and the MES level.
