+The ISO naming conventions shown in the figure above can be realized by providing the configuration shown below as input to the HIM configurator,
+and inserting the "instances0/1" directives in the related vspec files.
+```
+    "instances": {
+        "Axle": [
+            "Row[1,4]",
+            [
+                ["Pos7","Pos9"],
+                ["Pos7","Pos9"],
+                ["Pos6","Pos7", "Pos9","Pos10"],
+                ["Pos8"]
