Parameter Descriptions
MISSED S MARKS
Range: 0 -
Diagnostic counter for missing (late) marks. Missing marks are those that occur after the
window.
MASTER MARKS
Range: 0 -
Diagnostic counter for valid marks. If the block is not in reset, length is calculated when a
new valid mark has arrived.
SLAVE MARKS
Range: 0 -
Diagnostic counter for valid marks. If the block is not in reset, length is calculated when a
new valid mark has arrived.
READY
Range: FALSE / TRUE
This is set FALSE by reset or power-on. It goes TRUE after the initial repeat counter is
passed.
SLAVE MARK POS
Range: —.xxxx
Indicates the distance to the slave mark.
MASTER MARK POS
Range: —.xxxx
Indicates the distance to the slave mark.
RESET
Range: FALSE / TRUE
If TRUE, then the length counters are reset to zero. The length outputs are set to their
nominal values and the repeat counter is reset setting the filter time constant to INITIAL
FILTER. When the function block comes out of reset, the counters and length calculation will
become active again.
ENABLE
Range: FALSE / TRUE
If FALSE, then the length counters are reset to zero. RESET and ENABLE are functionally
equivalent. RESET being the inverse of ENABLE.
HOLD
Range: FALSE / TRUE
If TRUE the length calculation is suspended and the last outputs are held..
NOM MASTER LEN
Range: 0.0000 to 100.0000
The nominal length to the next required mark.
NOM SLAVE LENGTH
Range: 0.0000 to 100.0000
The nominal length to the next required mark.
TOLERANCE
Range: 0.0000 to 10.0000
The size of the window within which the Good Mark is expected to appear. Setting to a value
of 2.0000 provides a window of size -2.0000 to +2.0000.
INITIAL FILTER
Range: 0.000 to 300.000
The length filter value used during the start-up phase (while the block is not “READY”) See
also “FILTER”
FILTER
Range: 0.000 to 300.000
The filter is run only when a new valid mark has arrived (this ties the filter Tc to the number
of marks per second, and not time).
RESET COUNTERS
Range: FALSE / TRUE
Resetting the counters (TRUE) clears the error counters but
does not
clear the repeat
counters and so leaves the filter Tc unchanged.
