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).
