The command string is further defined:
/*the below C code will define an array called msg which will contain the Max Meas Mode Command String*/
unsigned char msg[4]; /*declare four byte unsigned character array using C language */
msg[0]=248; /*control byte */
msg[1]=65; /*assume the controller ID is the letter A */
msg[2]=84; /*assume initiation byte which is the ASCII letter T */
msg[3]=13; /*termination byte */
When the host sends this string, the control module sends the maximum values stored from the previous scanned object. If
the sensor is presently scanning an object when the message is sent, the control module gives the maximum values for the
present object.
8.4 Glossary
Blanked Beam
A beam that is ignored by the receiver, as a result of a blanking program being applied to it. Beams (or
groups of beams) are blanked when a component or fixture will remain in or move through the light
screen array; blanking the affected beams prevents the component or fixture from causing false
outputs.
Blocked Beam
A beam that is obstructed between the emitter and the receiver, and is not blanked.
Clear Beam
A beam that runs unobstructed from the emitter to the receiver (same as a made or unblocked beam).
Excess Gain
A measurement of the amount of light falling on the receiver from the emitter over and above the
minimum amount required for operation. A-GAGE High-Resolution MINI-ARRAY emitters and receivers
automatically perform an Alignment procedure to equalize the amount of excess gain at each element
along the array.
Host
A computer or process controller that controls and receives input from the High-Resolution MINI-
ARRAY System, and/or other equipment and systems within a factory.
Made Beam
A beam that runs unobstructed from the emitter to the receiver (same as an unblocked or clear beam).
Unblocked Beam A beam that runs unobstructed from the emitter to the receiver (same as a made or clear beam).
