The PLC requests a function by entering the required function code in
the mDiag1Output1 variable.
If a function is to be sent with parameter, first the parameter has to be
entered in mDiag1Output2 and then the function code in
mDiag1Output1.
After the function has been executed the function code is always
displayed in mDiag1Input1, while the diagnosis data can be read in
mDiag1Input2
.

Direct assignment in 32-bit variables is also possible (e.g. %QD1256
and %ID1256).
* Here "CAN processor" refers to the hardware and software of the
CANopen interface.
