Main group 4/subgroup a: Write R parameters in PLC signal words
@4a3 <Value 1> <Value 2> <Value 3> <Value>
The state of a flag word in the PLC is loaded via a parameter, pointer or constant.
The PLC number is defined by <Value 1> and the word address by <Value 2>. The
dimension identifier <Value 3> specifies how the state of the PLC flag word is to be
loaded.
