Converting Step 5 programs to S5 for Windows

S5 for Windows has an Integrated Import Filter. PLC programs created with the basic PLC programming package STEP® 5 from SIEMENS with a DOS operating system (or S5-DOS) may directly be imported.

The import function converts a *.S5D program file into the S5 for Windows file format by reading the data from the disk into the memory of your personal computer.
Files created with the SIEMENS STEP® 5 software have a file name with six (6) freely selected characters plus the characters ST. The characters .S5D are used as the file name extension.

• Example: DEMO12ST.S5D.

At the same time the PLC program file is converted, the symbolic table file is read into the memory of your personal computer. This file has the same name as the PLC program file (the first six characters), followed by the characters Z0 and the file name extension .SEQ.

• Example: DEMO12Z0.SEQ.

The original files on disk are not touched by the conversion program. They remain in their original format.

During conversion, each blocks creation date and time is assigned. This is the date and time the original program was last saved (DOS file date).
A dialog box gives you the ability to select a PLC program file in the SIEMENS S5D format to open. The corresponding symbolic file is opened automatically.
