Beh

Since the logical device controls all logical nodes that are part of the logical device, the mode of the logical device ("LDMode” = LLNO.Mod) and the mode of a specific logical node (“LNMode” = XXXX.Mod) are related. The behaviour of a logical node is therefore a combination of LLNO.Mod and XXXX.Mod and is described in the "LNBeh” = XXXX.Beh. This data object is read-only and has the same possible values as Mod (Mode). The value is determined according the following table:
