OPERAND SELECT
Used to select an operand to associate with the operation. The
operand is the condition being evaluated by the operation, in order
to determine the logic state. This can be an external variable, such
as a physical inputs, or internal variables, such as bit flags. Only the
operands appropriate for the chosen operation type will be
displayed.
Figure 12.30 - Operand Display / Selection / Comment Screen
The functions on this screen perform as follows:
COMMENTS -
Each operand may have a comment, with
up to eight characters, associated with it. In addition, each rung can
have up to a 64 character comment. These comments are
downloaded and stored with the PLC program, so that the user will
always have them available when he uploading a program from an
Axiom Plus.
READ-ONLY OPERANDS
PHYSICAL INPUTS (IN
) - Each of these operands corresponds
directly to the sensed value of one of the 15 available physical
inputs.
