4 Reads/Writes Robot's Variables
4.1 Function Description
(1) Function list
The table below lists the variable operations performed from the GOT:
Table 4-1:Variable operation function list
(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.
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.
4.2 Operation Flow
No Item Description
Robot's
response time
