Creating a Comparison Contact and Typing a
Constant
A comparison contact can be inserted not only in one of the three ways described in section 6.5.7, but also by
means of the following steps. Users need to put network 7 under network 6, and write the program shown
below.
(1) Click on the toolbar, and then select a type (>= in this example).
(2) Click on the toolbar, and then move the mouse cursor to the position where the comparison contact
will be inserted. The mouse cursor appears as a comparison contact when the mosue is moved to the left
side of the red frame, the right side of the red frame, or the bottom of the red frame. The users can decide
where to insert the comparison contact. After the users decided on a position, they can click the left
mouse button to insert the comparison contact.
Write the program shown below in the way described above. In WPLSoft, a decimal value is preceded by K,
and a hexadecimal value is preceded by H. If users want to type a decimal value in ISPSoft, they can type it
directly. If users wan to type a hexadeicmal value in ISPSoft, they have to type “16#” and the hexadecimal
value, e.g. 16#7FFF. In ISPSoft, an octal value is preceded by 8#, and a binary value is preceded by 2#.
