8-2-2 Variables
Variable are used in a program to hold data. The following variables can be used with the SRCP
controller.
■ Point variable P
A point variable can contain a point number. It is used in movement commands such as MOVA
and MOVI statements instead of specifying the point number directly. Sometimes the number of
program steps can be reduced by using point variables.
■ Counter array variable C, Counter variable D
A counter variable can contain counter values and is used to specify the pallet work position
number in a palletizing program and to count the number of runs. A counter array variable is an
array of a total of 32 counter variables that can be selected by the CSEL statement of robot lan-
guage.
■ Flag variable: memory input/output 100 to 147
A flag variable can only have a data value of 1 (ON) or 0 (OFF). It is used in a multi-task program
to synchronize between tasks or in a condition judgement program.
Memory I/O from 100 to 131 can be freely turned on or off by the user or their values can be
referenced. However, outputs 132 to 147 are controlled by the system so the user can only refer to
their values.
