Reading and Writing Device Data
The following tables show how to generally access data of the devices connected to port one to port four of the
MTQ22-FBP.0. The manuals of the connected devices are also needed to understand what data is provided and to derive the
length of the input and output data telegrams from it.
The tables in this document show the mapping of the most common input, output and diagnosis data, that can be accessed
very fast with one single read or write command.
Generally it is possible to read all data from the UMC100.3. All registers are listed in the separate document
2CDC135068M0201, that can be downloaded from the ABB product web page.
In the following tables the same data types are shown in the same color for an easier identification.
Individual data access by device
This method makes it possible to individually access data from a connected device via single registers or groups of registers
organized in words.
