Import and Export of PLC Programs

Existing PLC Programs
You can still use your valuable PLC program library. Importing and the exporting existing PLC programs is easily done with S5 for Windows® and S7 for Windows®.
S5 PLC programs stored on disk in a CPM format can be converted into DOS disks with a converter program. S5 for Windows® imports the converted files.

S7 Programs
PLC Programs created with the S7 for Windows® programming package can be transported into the original Siemens STEP® 7 programming system.
The Export function stores the PLC Program (file extension .AWL) and the Symbolic Table (file extension .SEQ) in an ASCII text file format on disk.
A Disk created with the S7 for Windows® Export function can be read (imported) by a Siemens programming system.
PLC programs written with a Siemens STEP® 7 programming system and S7 program libraries can directly be imported by S7 for Windows®.

Importing [S5D - Format]
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), can be opened directly.
The import function creates an S5 for Windows® project without altering the original files.
It is also possible to converts the files into the S5 for Windows® format by reading the data from the disk into the memory of your personal computer.
Files created with SIEMENS 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.
For 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. For example; DEMO12Z0.SEQ.
The conversion program does not alter the original files.

Exporting [S5D - Format]
An export filter is also integrated in SS5 for Windows®. This filter converts PLC programs in the STEP® 5 format S5D.
A PLC program existing in the memory of your personal computer is automatically converted during the write process to the disk.
The file name has six (6) freely selected characters plus the characters ST. The characters S5D are used as the file name extension.
The symbol table relating to the PLC program is also stored on disk during this process. The symbol file gets the same name as the program file (the first six characters) followed by Z0 and the file name extension SEQ.

CPM Format
If your PLC programs have been created with one of the following SIEMENS programming systems, PG-685, PG-675 or PG-635 in CPM, they must be converted in DOS disk format.
We can supply the shareware converter program Sydex "22DISK". The converted files can be imported by S5 for Windows.
