About Position Capture: The master encoder position can be captured only by the Master Trigger input
(input #5), and only when that input is defined as a "trigger interrupt" input with the
(see
command). When the "trigger interrupt" input is activated (active edge), the master encoder
INFNC
position is captured and the position is available through the use of the
display command.
Position Capture Status, Longevity of Captured Position: Use the

is an assignment/comparison operator for using the status information in a conditional expression
TRIG
(e.g., in an
statement). Once the captured master encoder position value is assigned/compared with the

operator,

Position Capture Accuracy: The master encoder position capture accuracy is ±1 encoder count.

VAR1=PCME
; Assign captured master encoder position to variable 1
; (position was captured when master trigger became active)
IF(PCME<4000)
; If the captured master encoder position

; less than 4000, do the IF statement
VAR2=PCME+10
; Add 10 to the captured master encoder position
; (captured when master trigger input became active) and
; assign the sum to variable #2
