Example Programming
0.00
0.02
The following example shows two different
block programs controlled by CIO 0.00 and
CIO 0.02.
The first block executes one of two additions
depending on the status of CIO 0.01. This
block is executed when CIO 0.00 is ON. If CIO
0.01 is ON, 1 is added to the contents of CIO
1. If CIO 0.01 is OFF, 2 is added to the
contents of CIO 1. In either case, the result is
placed in D0.

The second block is executed when CIO 0.02 is
ON and shows nesting two levels. If CIO 0.03
and CIO 0.04 are both ON, the contents of CIO
1200 and CIO 2 are added and the result is
placed in D10 and then 0001 is moved into D11
based on the status of CY. If either CIO 0.03 or
CIO 0.04 is OFF, then the entire addition
operation is skipped and CIO 3.01 is turned
ON.
