Overview



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.

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.
