Example 3 - Monthly Time Setting
A Monthly setting does not have a constant setting for either the Month or the Year. These
parameters will be ON constantly and must therefore be set to a default value. The Value for
the Year Parameter is 08 H and the value for the Month is 01 H.
Write a Monthly Setting to turn On the Time Switch set up as CW03 on the 25th of every month
at 08:35 AM.
Year Value = 8 (default); Month Value = 1 (default); Day Value = 25; Hour Value = 08; Min Value
= 35; On/Off Value = 1.
Installing the values from the Table above into the Date Parameter Table above and calculating
the Hexadecimal values for each line gives the following values.
Note:
*1, *2, *3 and *4 settings correspond to Table 7.22.
