Hello drn5; A few years ago there was a similar question discussed on the forum, and our friend Marcjan provided a document showing how a S7-200 could be filled with 2 EM 277 Profibus slave modules. I saved it on my hard disk at the time, and I am attaching ot here for your examination. In Marcjan's configuration, there was ony one Profibus master (a S7-300) connecting to both EM 277s, so the same Profibus master address was used in the configuration of both. The main difference in the configuration of each EM 277 was the V-memory addresses reserved for each in MicroWin. If you have 2 distinct Profibus masters, you will have to configure the correct master address for each EM 277 slave. Hope this helps, Daniel Chartier AttachmentMarcjan_ multiple Em 277.pdf (665 Downloads) |
