9-109 Vision Sensor Dedicated Commands and Status Variables
[Explanation]
1) In an NVPST command or NVIN command, when a <type> of "1" or "3" or “5” or “7” is specified, the
data recognized by the vision sensor is stored in numeric data format.
2) The stored data is held until the next NVPST command or NVIN command is executed. However, this
data is cleared (to 0) by a program reset, END command, or power supply reset.
Also, if anything other than "1" and "3" and “5” and “7” is specified as the type with the NVPST
command or NVIN command, the data is cleared to "0".
3) If the acquired data is a vision program function or character string, "0" is stored in the corresponding
axis.
4) 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 specification specifies other than "1" through "30", 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.
