FX Series Positioning Controllers
f Applicable devices
Devices such as X, Y, M and D can be used as operands.
X, Y and M can be used as bit devices or word devices (Refer to "5.6.3 Bit devices".).
The data registers D (16-bit) and the index registers V (16-bit) and Z (32-bit) are handled as
data.
The expression shown on the left indicates that con-
stants K and H, group bit devices KnX, KnY and KnM,
data registers D and index registers V and Z are appli-
cable as operands (S1 x ) and (S2 x ) .
And this expression also indicates that bit devices Y
and M can be specified as (D x ).
• The indexes V0 to V7 and Z0 to Z7 cannot be further indexed. (For example, V0Z is invalid.)
g Execution format
The instructions handling 16-bit numbers as well as 32-bit numbers are indicated by prefix-
ing the symbol [D] (Refer to "5.6.4 Data length and instruction execution format".).
h Description
The basic contents such as what the instruction can do, how the operands must be set, etc.
are described here.
Application instruction drive input
An application instruction can either be driven via some contact or directly driven without
regard to any contact.
The instructions FNC 03 to FNC 09 are exceptions, and are always driven directly without
regard to any contact.
In the case of an application instruction which is driven via some contact, it is not executed
when the drive input is OFF (as if the instruction is skipped by the jump function.)
The contact circuits are automatically reset when a positioning control instructions, m code
instructions, FNC 03 to FNC 05, FNC 08 and FNC 09, etc. are specified in the program. After
that, program execution returns to the bus line.
