Real Time Clock
Next we need to set up the four outputs to come on individually in the four different
quadrants of a minute. Output %Q01 will be on between 0-15s, %Q02 16-30s, %Q03
31-45s and %Q04 46-59s. However they will only come on if it is during the working
period.
Start a new Rung with a N/O coil and assign it to %M01. On the same Rung insert a
Limit function with the limits for %Q01. After the limit function insert a N/O coil and
assign it to %Q01.
Repeat this code for the remaining outputs.
