When inputting data to the time delay
function block TT1, a window auto-
matically opens for the inputting of
the various parameters.
In the first programming line, each
pulse at input I1 increments or dec-
rements the counter C1.
Input I2 determines the counting
direction, either up or down.
The insertion of the clock block will
enable output Q1 to change state in
accordance with the preset time
zones.
From Monday to Friday, the active
time zone will be from 8: 00 (ON)
until 21: 00 (OFF).
For Saturday and Sunday, the active
time zone will be from 9: 00 (ON)
until 12: 00 (OFF)
The analogue function block controls
output Q 4 according to the result of
the comparison.
In this example, output Q 4 changes
state when the value of the analogue
input IC is greater than the 6.4 V
reference voltage.
