Hello ahsan; The EM 277 is a Profibus slave module, and as such will turn the S7-200 into a Profibus slave responding to a Profibus master in the project; it cannot "monitor" a program on another unit, only exchange data when the Profibus master requests it (in read/write format). The attached screencapture is from the S7-200 system manual: https://support.industry.siemens.com/cs/ww/en/view/1109582
And look up the following FAQ, to guide you in your project; in this case the S7-300 acts as a Profibus master: How can you communicate data between the S7-200 and the S7-300 via PROFIBUS DP? https://support.industry.siemens.com/cs/ww/en/view/2615830 As far as WinCC connections are concerned, please refer to this document: What are the options for accessing an S7-200 with WinCC? https://support.industry.siemens.com/cs/ww/en/view/21915573 And follow the link provided to configure the EM 277 with a PC running WinCC. Hope this helps, Daniel Chartier

Hello ahsan; If the PC where Microwin is installed has a Profibus CP installed, then it is possible. No program blocks necessary, only adjustments of the communication configuration through PG/PC Interface. See the following discussion: https://support.industry.siemens.com/tf/ww/en/posts/8420/ You should be able to locate more information on the subject by using the search box on the right of this page. That way you can (must!) ask very clear questions and not get annoyed by the ramblings of the members here. Hope this helps, Daniel Chartier |
