Posted 13 Jan 2016 (edited) Hi experts, I successfully connect S7-314 2PN/DP to HMI Mitsubishi GS2107 using ethernet cable, and the the ethernet connection type is OP communication. In But when I connect one more S7-1200 to GS, there is a problem about station number. In Mitsubishi connection manual, they ask to correct the station No. of the connected Ethernet module (the picture is in attachment). So does anyone know how to assign the station number to ethernet module of S7-1214 and S7-314 Edited 26 Jan 2016 by anhtuandrg Share this post Link to post Share on other sites
