Program examples
1. When reading the current value of a timer and counter
2. When indirectly specifying the set value of a timer or counter
As the set value of the timer T20, two values can be specified by turning ON or OFF the switch X002.
For specifying more than two set values, more than one switch is required.
3. When transferring a bit device
The program written by basic instructions shown on the right can be expressed using MOV instruction as shown
below.
4. When transferring 32-bit data
Make sure to use DMOV instruction for transferring the operation result of an applied instruction (such as MUL) whose
operation result is output in 32 bits, and for transferring a 32-bit numeric value or transferring the current value of a
high-speed counter (C235 to C255) which is a 32-bit device.
