Modbus Interface Definitions
The unit offers a Modbus address table with for visualizing systems. The table contains 16 bit integer (short) and
32 bit integer (long) variables. The contents of some measurement long variables are also available as short va-
riables. To cover all measurement ranges in a satisfying resolution, the engineering unit “Watt”, “Volt” and
“Ampere” can be adjusted according to the application.
