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.
"Bit devices" and "Bit designated word devices" can be used as bit data.
When using bit devices
Bit devices are designated in one-point units.
Using word devices
Word devices enable the use of a designated bit number 1/0 as bit data by the designation of that bit number.
Word device bit designation is done by designating "[Word device].[Bit No.]". (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).
