• HARDNET-IE S7-REDCONNECT contains the functional scope of the HARDNET-IE S7 software package (S7-communication, open communication and PG/OP communication) as well as additional redundant communication over S7 connections. No additional license is required for HARDNET-IE S7.
• Open communication
• Time synchronization
• Existing Windows applications can be used
• Services for monitoring the redundant communication
• Diagnostic tool for visualizing the communication status
• Simple redundancy over 2-way communication (STEP 7 V5.0 SP2 and higher)
• Enhanced redundancy over 4-way communication (STEP 7 V5.1 + SP4 and higher)

Fault-tolerant S7 communication is carried out via a standard connection and a standby connection. These are monitored during operation and switched in the event of a fault. With HARDNET-IE S7-REDCONNECT, these remain hidden from the PC application.

Fault detection, changeover (if required), communication monitoring, and synchronization are all invisible to the application.

The application, e.g. WinCC, communicates with both subunits of the S7-400H as with an S7-CPU.

User interfaces

OPC interface

The OPC server included in the respective software package can be used as the standard programming interface for the S7 communication and open communication protocols in order to connect automation technology applications to OPC-compatible Windows applications such as Office, HMI systems, etc.

Configuration

• H-connections are configured and engineered using STEP 7 (V5.0 to V5.5)
