9-107 Vision Sensor Dedicated Commands and Status Variables
[Explanation]
1) In an NVPST command or NVIN command, when a <type> of "0" is specified, the data recognized by
the vision sensor is stored in position data format.
2) When this variable is used, write the vision program to store the data in the order X, Y, and C.
Example:
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. Even if the continue function
is enabled, the data is cleared (to 0 for all axes) for a power supply reset.
4) Also, if anything other than "0" is specified as the type with the NVPST command or NVIN command, all
axes are cleared to "0".
5) If the acquired data is a vision program function or character string, "0" is stored in the corresponding
axis.
6) The data for this variable is the valid position data for 8 axes.
7) 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 other than "1" through "30" is specified, an
"array element mistake"
error occurs.
