Read the daylight saving time function (refer to example 1-3)
When the operand S is 2, the function of daylight saving time is being read. S
daylight saving time; S
daylight saving time; unit: minute. When S is set to read the state of the daylight saving function and the output state
of D is ON, the PLC saves the setting values in the operands S
the device is set to K or 16#, the values are not saved, the SM0 is ON, and the error code in SR0 is 16#2003.
Devices with firmware version after V1.04 (V1.04 included) adds 4 to the function codes in S, after the daylight saving
state is read. For example, after the daylight saving state is read, the function codes 0, 1, 3 become 4, 5 and 7.
