Clock buffer
In LOGO! 230RC, the internal clock continues to run when there is a
power failure. In other words, the clock has reserve power. How much
reserve power LOGO! 230 RC has depends on the ambient temperature.
At a temperature of 40, it has reserve power for 8 hours.
Cam overlap
You use the cams to set switch-on and switch-off times. At a switch-on
time, the clock switches the output on unless it was already on; at a
switch-off time, it switches the output off unless it was already off.

Priority
If you specify a switch-on time and a switch-off time at the same time for
different cams, the switch-on/switch-off times contradict each other. In
this case, cam No3 has priority over cam No2, and cam No2 has priority
over cam No1.
