Image of the outputs of the valve terminal
Access to the outputs of the valve terminal takes
place with 8 %MW words in the output 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.

Fields 0...63 contain the current status (logic 0 or 1) with which the outputs are
controlled, providing these exist physically. In accordance with basic rule 3, the
valves are addressed first and then the digital outputs. Max. 64 output bits are
used by the valve terminal.
