Designating Data

The following six types of data can be used with CPU module instructions.
Data that can be handled by
CPU module
3.2.1
Using bit data
Bit data is data used in one-bit units, such as for contacts 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.
Word device
(b) Word device bit designation is done by designating "
(Designation of bit numbers is done in hexadecimal.)
For example, bit 5 (b5) of D0 is designated as D0.5, and bit 10 (b10) of D0 is designated
as D0.A. However, there can be no bit designation for timers (T), retentive timers (ST),
counters (C) or index register (Z). (Example Z0.0 is not available).
