Designating Data; Using Bit Data - Mitsubishi MELSEC QCPU Programming Manual

3 CONFIGURATION OF INSTRUCTIONS
(3) Number of devices and number of transfers (n)
(a) The number of devices and number of transfers designate the numbers of devices and
transfers used by instructions involving multiple devices.
Example: Block transfer instruction
(b) The number of devices or number of transfers can be set between 0 and 32767.
However, if the number is 0, the instruction will be a no-operation instruction.

3.2 Designating Data

The following five types of data can be used with CPU module instructions:
Data that can be
handled by CPU

3.2.1 Using bit data

Bit data is data used in one-bit units, such as for contact points or coils. "Bit devices" and "Bit
designated word devices" can be used as bit data.
(1) When using bit devices
Bit devices are designated in one-point units.
M0
(2) Using word devices
(a) Word devices enable the use of a designated bit number 1/0 as bit data by the designation
of that bit number.
