Hello William B. first things first: An I-Device is an I-Device, be it an S7-1200 (loooooooong overdue that it supports this) or an S7-300, S7-400 or any other I-Device. A good description of what an I-Device is and how it can be used can be found in the SIMATIC PROFINET System Description (see especially chapter 4.8). Depending on the application, there's a fair few advantages to be had by using I-Device functionality, also in combination withshared Device and/or I/O Controller functionality at the same time (if supported by the CPU), so it is definetely worth while reading up on this in the above manual in my opinion. I hope this helps |

Hello William B. I will (have to) be possible as the 1200 as of V4.0 supports I-Device functionality. You've already manged a configuration in TIA Portal, it is also described in the latest 1200 manual (see huggy_d1'slink), so just go for ti and try it out. @ huggy_d1 Data exchange between an I/O Controller and an I-Device is based on Profinet I/O's and handled by the OS. Just to avoid further confusion, there isno "hiding the get/put instructions in the background" going on (Get/Put are based on S7 communicationswhich is quite different toProfinet I/O). |
