• Provides clarifications and corrections to the second edition of IEC 61850-7-4, based on the tissues = { 650, 671, 672, 674, 675, 676, 677, 679, 680, 682, 683, 685, 686, 689, 693, 694, 695, 696, 712, 713, 714, 715, 716, 722, 724, 725, 726, 727, 732, 734, 735, 736, 742, 743, 744, 748, 749, 772, 773, 774, 775, 776, 800, 802, 808, 819, 830, 831, 835, 838, 842, 843, 844, 849, 871, 877, 878, 879, 881, 882, 902, 908, 909, 910, 911, 912, 913, 920, 928, 932, 933, 937, 939, 940, 952, 967, 991, 1007, 1029, 1044, 1046, 1071, 1075, 1076, 1077, 1081, 1086, 1117, 1119, 1128, 1137, 1139, 1176, 1177, 1190, 1191, 1203, 1205, 1229, 1235, 1236, 1244, 1250, 1256, 1258, 1259, ... }
• Adds to each functional LN group a parent abstract Logical node where the functional nodes are children from (full object oriented model). Since all abstract LNs are in together in a common clause, the relative position of the functional LNs is not changed within their clause
• Adds new abbreviated terms
• Has extension of the list of abbreviate terms to be used for object names
• Has more precise combination rules for abbreviated terms to object names
• Has extensions by new logical nodes mainly from power quality domains and others
• Has corrections of editorial errors.
