Fields 0...63 contain the current status (logic 0 or 1) of the digital inputs,
providing these exist physically. Non-existent inputs are logic 0. Max. 64 input
bits are occupied by the valve terminal.
The four status bits of the valve terminal are always formed after the physically
existing inputs. The exact position and meaning of the status bits can be found
in chapter 5.4.

Access to the inputs of the valve terminal takes
place with 8 %MW words in the input table
defined in the configuration editor. This table is
read cyclically at the start of the control cycle
(before the user program is executed) and
updated. The contents of the table are explained
below.
