The content of the data request will be contained in a data block structure. Expand the PLC in the
project tree and add a new block.
The data block will be added to the program blocks with the specified name. Add two structures
(RequestRecord and ResponseRecord) to the data block. Create the structure of the records accord-
ing to the specification, like on the screenshot below. Enter the start value for the variables so that
