14.1.2 Accessing the variables in a single-channel system
Name of the variables
The generic mnemonic associated with the variables is written as
follows.
(V.){prefix}.{variable}
The mnemonic associated with each variable starts with a (V.). Use
these characters (except the parenthesis) when accessing from PRG;
but do not use them when accessing from INT and PLC.
Axis and spindle parameters
Axis and spindle variables are identified with the prefix –A.–. When
these variables refer to a spindle, they may also be accessed with the
prefix –SP.–.
(V.)A.{variable}.{axis/spindle}
(V.)SP.{variable}.{spindle}
The variables of the machine parameters with –MPA.– prefix can also
be accessed using the –SP– prefix when referring to a spindle.
(V.)MPA.{variable}.{axis/spindle}
(V.)SP.{variable}.{spindle}
In these variables one must indicate which axis or spindle they refer
to. The axis may be referred to by its name or logic number; the spindle
may be referred to by its name, logic number or index in the spindle
system.
Identifying the axes and the spindles.
In variables with the prefix –A.– and –MPA.–, the axes and the spindles
are identified with their logic number.
• For the axes, the logic number sets the order AXISNAME.
• For spindles, the logic number is given by the sum of NAXIS +
orden SPDLNAME.
In variables with the prefix –SP.–, the spindles are identified with their
index in the system, according to the order SPDLNAME.
Variables of the master spindle
They are special variables that may be used to access the data of the
master spindle without knowing its name or number. They are meant
for displaying data and programming cycles.
The variables are identified with the prefix –SP.– but without indicating
the spindle.
Mnemonic PRG PLC / INT
(V.)MPG.NAXIS V.MPG.NAXIS MPG.NAXIS
(V.)SP.{var} Variable of the master spindle.
