    A TIA Portal project archive (.zap11 to .zap21), a TIA Portal project folder as a .zip, a STEP 7 project folder as a .zip or a STEP 7 archive, or a STEP 5 program file (.S5D, together with its Z0.SEQ symbol file if you have it). You can also add the System/PEData.plf file of a TIA Portal project directly.

      Another version of the same project (any of the kinds above). You get a report of added, removed and changed blocks, networks, interface members, tags and hardware, from the first project to this one.

      International (A, AN, O, = ...) or German (U, UN, O, = ...) instruction names in STL and AWL code. Automatic uses German for projects written in German and international names otherwise.

      Open a STEP 5 S5D file

      STEP 5 programs for the S5-90U to S5-155U still run in plenty of old machines. The program lives in one .S5D file (for example BISSO@ST.S5D), and the symbols and comments in a separate Z0.SEQ file next to it. The DOS software that reads them is hard to run today. Upload the files here and read the program in a browser or on paper.

      What to upload

      • The .S5D program file, and its Z0.SEQ symbol file if you have it: both in the same upload. Without the symbol file the program still reads, with absolute addresses only.
      • Or the whole project folder as a .zip; the files are found by name.
      • The .INI settings file can come along, but it is not needed.

      What comes out

      • A printout (PDF) of every block (OB, PB, SB, FB, FX, DB, DX) in STL with its networks, the symbols and comments by each operand, the data blocks with their values, the symbol list and a cross reference of inputs, outputs, flags, timers and counters.
      • An offline viewer (HTML) with the block list and a search box.
      • STL sources and the symbols, data and cross reference as CSV and Excel.

      The instruction names can be international (A, AN, O, =) or German (U, UN, O, =). By default the tool follows the symbol file: German when its addresses are written as E, A and M, international when they are I, Q and F.

      Things to know

      • A symbol file alone holds no program. If only the Z0.SEQ file comes through, the page says so; look for the ST.S5D file next to it.
      • Programs are shown as STL. STEP 5 LAD and CSF views are not drawn.
      • Compare two copies: upload one under "Second version to compare" to see which blocks, networks and comments changed, for example between the copy in the machine and the one on file.
