Hello Red; I cannot find such a "mask", and I doubt it can be found. My experience is that the S7-200 Microwin program was not developed by "regular" Siemens personnel, but by TI programmers when they were absorbed in the Siemens family and put in charge of developing this "new" platform for a brick PLC, around 1991. So basically S7-200 (and MicroWin) follow a TI structure more than a Simatic one, and fiuctions were never interchangeable between the s7-200 and s7-300 platforms. For example, Microwin still uses subroutines (like a TI 505, or TI 405) instead of FBs, a basic resource in the Step 7 and TIA Portal programming softwares. And there are no DBs in the S7-200, only VW registers... So I do not believe it would be easy to delevop an "overlay" that would allow you to develop a program for a S7-200 CPU, behind the mask of an S7-21200. In any case, the consensus of members on the forum seem to support this: https://support.industry.siemens.com/tf/ww/en/posts/124024/ https://support.industry.siemens.com/tf/ww/en/posts/121609/ Hope this helps, Daniel Chartier |
