3. Indexing
Devices used in AND and ANI instruction can be indexed with index registers (V and Z).
(State relays (S), special auxiliary relays (M), 32-bit counters (C), and "D .b" cannot be indexed.)

4. Bit specification of data register (D)
A bit in data register (D) can be specified as a device used in AND and ANI instructions.

Errors
• When an I/O number used in AND or ANI instruction does not exist due to indexing, M8316 (Non-existing I/O
specification error) turns ON.
• When the device number of a device (M, T or C) other than I/O used in AND or ANI instruction does not exist due to
indexing, an operation error (error code: 6706) occurs.

The index registers V0 to V7 and Z0 to Z7 are
available for indexing.
When a used device is an input (X) or output (Y),
the value of an index register (V, Z) is converted

When specifying a bit in data register, input "."
after a data register (D) number, and then input a
bit number (0 to F) consecutively.
Only 16-bit data registers are available.
