With the introduction of Siemens STEP 5/ST V7.0, there is now an identical software package for programming devices and PCs. After installation on either type of system, Siemens STEP 5/ST cannot be copied.
The Siemens STEP 5 driver works in conjunction with KEPServerEX to exchange data between OPC clients and Siemens S5 PLCs using the AS511 protocol, which allows a direct connection to the programming port of the PLC. The programming port utilizes a Current Loop connection, requiring the use of either the supplied programming cable or an external RS-232 to Current Loop converter. For more information on wiring and recommendations for Current Loop converters, refer to the product manual. KEPServerEX automatically optimizes data acquisition based on client demand and ensures data integrity through extensive error handling.
Supports direct Peer-to-Peer Current Loop connections from the PC serial port
Supports Ethernet Encapsulation, though the protocol’s tight timing requirements may preclude the driver from working in all Ethernet network environments
Supports multiple PLC connections when using Ethernet Encapsulation
Supports the following Memory Types: I, Q, F, T, C, and Data Block Access by named type
Supports all data types
Automatic dial configuration
Multiple phone number management
