IBHsoftec GmbH OPC Server V4.x

The IBH OPC Server permits OPC client applications like SCADA systems, to connect to PLCs of the Siemens SIMATIC® S5 and the SIMATIC® S7 series. It is also possible to access data simultaneously from several PLC Controls. Even a mixed S5 and S7 operation is possible. All modern SCADA systems are usually designed to be an OPC client.

PLCs may be accessed via the following protocols:

• SIMATIC® S5:
• AS511 serial / USB
• IBHLink S5 TCP/IP and IBHLink S5++ TCP/IP
• IBHsoftec SoftPLC internal und external
• INAT TCP/IP
• INAT H1

• SIMATIC® S7-300/400:
• MPI Adaptor serial / USB
• IBHLink S7 / IBHLink Plus / IBHLink S7++
• S7 TCP/IP to a CP343/443
• SimaticNet® (Set PG/PC Interface)
• IBHsoftec SoftPLC internal and external
• INAT H1

• SIMATIC® S7-200:
• PPI Adaptor serial / USB
• IBHLink S7 / IBHLink Plus / IBHLink S7++
• S7 TCP/IP to a CP243

• SIMATIC® S7-1200:
• S7 TCP/IP to the integrated CP

• LOGO!® (RCE versions)

The configuration of the Server is performed via the OPCEditor. A shortcut is installed on your PC.

One of the special features of the IBH OPC Server is to allow direct use of the absolute PLC Variables without declaration. It is also possible to use symbolic addressing as defined in the PLC program (Symbolic Table). Even variables used in S7 Data Blocks can be accessed via the IBH OPC Server with their symbolic names. These features eliminate the need of double declarations. To do so, the PLC program is assigned with the IBH OPCEditor to the PLCName and the required variables are selected within the user interface.

Server Configuration

Variable Syntax

For symbolic addresses, PLC programs in following formats may be used.

• SIMATIC® S5 (.S5D)
• SIMATIC® S7 (.S7P)
• S5/S7 for Windows® project (.S5P)
• S5/S7 for Windows® program file (.S5)
• Symbolic table (.SEQ)
