Communication objects
Note
As standard, the write flag (with the exception of 1 bit communication objects) is deleted with the com-
munication object values. Thus the communication object value cannot be changed via the bus. If this
function is required, the write flag must be set in ETS.
The communication object value is overwritten with the parameterized value after bus voltage recovery.
