11.6.2 Setting the clock by using ladder programs
The following shows a ladder program that takes the time data set in the F registers (FW100 through FW106)
and specifies it in the clock control registers (SW0280 through SW02E0) when X0000 is "1" (ON). Note that
Figure 11-11 explains only the items required to create the ladder program.

Operation overview
[1] When X0000 is ON, S0201 is set to "1", and a request to stop the clock is issued.
[2] The program verifies that the clock has stopped, and takes the time data (second, minute, hour, day, month,
year, and day of the week) that was previously specified in the F registers (FW100 through FW106) and
specifies it in the time registers (SW0280 through SW02E0).
F registers Time control registers
FW100 Second SW0280 Second
FW101 Minute SW0290 Minute
FW102 Hour SW02A0 Hour
FW103 Day SW02B0 Day
FW104 Month SW02C0 Month
FW105 Year SW02D0 Year
FW106 Day of the week SW02E0 Day of the week
[3] S0202 is set to "1", and a data set and start request is issued.
[4] The program verifies that the data set is complete, S0201 and S0202 return to "0", and the clock settings are
complete.
