Siemens Step 5 Software
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.
