ndVset
(Library)
Receives data from an external device (RS232C input/output).
ndVset (<2-digit integer>)
This statement provides a similar function to a VSET instruction in the conventional language.
The system receives data from an external device and adds (assigns) it to an internal variable after the robot sends a designated 2-digit integer to the external device. If you designate <2-digit integer> to "0", the system initializes an internal variable with "0".
