The data to write is moved from the input 'RECORD' by using a block move operation to the transfer
buffer. The user has to configure an array variable for this input with the corresponding number of ele-
ments.
Call FB 'Write_Rec_Ex'
The input 'ID' contains the IO-device number '21'. The index for the data to write to is 16#10. By set-
ting M40 the writing of the data is started. M41 indicates that the data from the global variable 'Wri-
te_Data1' has been successfully transferred to the IO-device.
