HARDNET-IE S7-REDCONNECT производства Siemens

The HARDNET-IE S7-REDCONNECT software package connects the SIMATIC S7-400H with applications on the PC such as WinCC.

A redundant Industrial Ethernet is typically used. The software package can also be used if SIMATIC H systems are operated on non-redundant networks.

Combined operation of redundant and single systems is also possible.

• Protects against communication failures arising from a fault in the double bus or in redundant rings
• Simplifies communication between a PC application and the SIMATIC S7-400H system
• Secures the investment thanks to the use of existing applications and flexible application options
• No additional programming overhead for the PC and in H systems
• Increases the availability of the PC application (e.g. PCS 7) thanks to redundant Layer 2 or Layer 3 communication

The following components are required to design a SIMATIC H system with PC connection

PC with:

• up to four CP 1613 A2/CP 1623/CP 1628¹⁾ and HARDNET-IE S7-REDCONNECT to connect the PC to Industrial Ethernet with ISO or ISO on TCP protocol

S7-400H with:

• CP 443-1 to connect the S7-400H to Industrial Ethernet with ISO or ISO on TCP protocol
• STEP 7 V5.0 or higher for programming

¹⁾ Available soon

• 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

As a standard programming interface for the S7 communication and open communication protocols, the OPC server contained in the respective software package can be used to connect the automation technology to OPC-compatible Windows applications (Office, HMI systems, etc.).

Configuration

• The S7 communication and open communication protocols are configured in STEP 7 NCM PC V5.1 SP2 or higher.
• The NCM PC configuration tool is included in the scope of supply of the HARDNET-IE S7-REDCONNECT software for Industrial Ethernet.
• NCM PC is a component part of Advanced PC Configuration.
