Tag Name Data Type Description
cmd1 DNPCROB
cmd2 DNPCROB
cmd3 DNPCROB
cmd4 DNPCROB
This object contains objects that define the status related to the module. Each of
these object types is discussed in the following topics of the document. The
ErrList member of the object stores the list of last 60 errors generated by the
module. This data is passed to the processor from the module the read block
100. Ladder logic transfers this information from the processor into the ErrList
array.
3.1.2 DNPSlvStat Object
The DNPSlvStat object stores the status data passed from the module to the
processor in the read blocks 112 to 114. This block of data contains information
that can be used to determine the "health" of the module and the tasks running.
The structure of the object is shown in the following example:
