4 Reads/Writes Robot's Variables

4.1 Function Description

(1) Function list
The table below lists the variable operations performed from the sequencer:
Table 4-1:Variable operation function list
No Item
1 Read numeric variable
2 Write numeric variable
3 Read position variable
4 Write position variable
5 Read joint variable
6 Write joint variable
(2) Functional requirements
Always available when a program is selected for robot's target slot and the target variable exists.
When the target is external variable, the variable operation is possible by specifying zero for a slot number,
even when a program is not selected.
CAUTION

No
Is variable operation necessary?
Carry out variable operation (read/ write)
Reads variable content by specifying slot number and variable name.
Rewrites variable content by specifying slot number, variable name, and vari-
able content.
Reads variable content by specifying slot number and variable name.
Rewrites variable content by specifying slot number, variable name, and vari-
able content.
Reads variable content by specifying slot number and variable name.
Rewrites variable content by specifying slot number, variable name, and vari-
able content.
Be careful fully to change variable value.
The robot's location and behavior may be changed by changing the variable value,
thereby interfering with surrounding devices. Because it is especially dangerous
when the robot is in operation, sufficiently check the value to be changed.
