Numerical value (n)
1
For the numerical values of the numbers of devices, transfers, data, and character strings, specify those used by an
instruction which uses multiple devices or an instruction which specifies the numbers of repetitions, data to be processed, and
character strings.
Ex.
Block transfer instruction
BMOV s d n
(1)
(1) The number of transfers executed by the BMOV instruction is specified.
A numerical value from 0 to 65535 or 0 to 4294967295 can be set for the size such as the number of devices, transfers, or
*1
characters.
Note, however, that when the size specification such as the number of devices, transfers, or characters is 0, the relevant
instruction results in non-processing.
*1 The setting range varies depending on the instruction. For details, refer to the description of each instruction.
Be careful when a large numerical value is used such as for the number of transfers. It delays the scan time.
