9 Detailed Explanation of Functions
[Explanation]
1) In an NVPST command or NVIN command, when a <type> of "2" or "3" or "6" or "7" is specified, the
data recognized by the vision sensor is stored in text string format.
However, kanji codes can not be acquired.
2) The maximum number of pieces of work that a vision sensor can recognize at one time is 255, but the
maximum number of sets of work information that a robot can acquire is 30.
3) The stored data is held until the next NVPST command or NVIN command is executed. However, this
data is cleared by a program reset, END command, or power supply reset.
Also, if anything other than "2" and "3" and "6" and "7" is specified as the type with the NVPST
command or NVIN command, the data is cleared to null.
4) If the acquired data is a vision program function or kanji code, a null character is stored in the
corresponding axis.
5) When using multi-mechanism mode, see the explanation of the NVPST command.
[Errors]
1) If the type of data specified as an array element is incorrect, a "syntax error in input command
statement" error occurs.
2) If there is an abnormal number of array elements (too many or too few), an "incorrect argument type"
error occurs.
3) If an array element 1 other than "1" through "30" is specified, an "array element mistake" error occurs.
4) If an array element 2 other than "1" through "10" is specified, an "array element mistake" error occurs.
