Hello abadabe; The link proposed in the preceding reply is te best guide to setup a DP/PA linkunder TIA Portal. Again: https://support.industry.siemens.com/cs/ww/en/view/79159361 Have you followed wery step as detailed? If you have a problem or an error message, at what point does it happen? The screenshot below shows the latest version of the DP/PA coupler you would need for this application. Hope this helps, Daniel Chartier |

Hello Abadabe; I do not understand your last question: what do you mean by "small"? Here is a link to this PA coupler's datasheet, you can see that it is a standard 80 mm-wide module: https://support.industry.siemens.com/cs/ca/en/pv/6ES7157-0AC85-0XA0/td?dl=en Study the manual to Siemens' Profibus couplers, you will find much information on the setup of a DP/PA link: https://support.industry.siemens.com/cs/ca/en/view/109805389 Hope this helps, |

Hello abadade; Basically you have decided to use a 3rd-party product wth your S7-1200 CPU. There is no problem doing so, all certified Profibus products must go through the same tests (from Profibus.com) to be allowed on Profibus/Profinet networks, and as such are recognzed to work with any Profibus master or Profiner IO Controller with similar effect. I will not enter into a manufacturers analysis, since all products are certified for Proifbus they are all comparable. However, you must then rely on the manufacturer data and manuals to operate them properly. The problem is that information on the Vega website on their PA-KOPPLER.X (which you are pointing to) are scarce, the product is marked as no longer available from Vega. In one of the downloadable documents named "Documents de Conformité" you will fing a notice that all documents concerning the PA-KOPPLER.X should be be found on the Pepperl + Fuchs website (see the screenshot below). The Pepperl + Fucks product documentation refers to their Profibus DPPA Coupler as a SK1 Segment Coupler model, and provdes an operating manual you should consult before setting up the coupler as part of your DP network: https://www.pepperl-fuchs.com/global/en/classid_260.htm?view=productdetails&prodid=7005#documents There are two special notices you should take into account to use the SK1 coupler as part of the Profibus DP network: - there is no need of a gsd file for the coupler, it is transparent to the DP configurator. However, the whole DP network(and all the slaves) must operate at a speed of 93,5 kB when teh SK1 is connectd to the DP network. - every PA slave you connect on the PA line from the SK1 will need to use their specific PA gsd file, integrated and configured in the master's DP configurator, and treated as a DP slave. Please refer to the SK1 operating manual for more details. Daniel Chartier |
