The M factor value expressed as a floating point number. This value is
multiplied by the counter actual count value, and gives the M factor a
range of +- TBD (Prior counter modules we produced have been +/-
3.2765). Most M factors will be within +- 5% of 1.0000.
MFactor[x] 0 - 1x10 32 FLOAT (C)
The R scale factor can be used for scaling of the output frequency. The
output frequency is divided by the R scale value. The frequency value is
divided by the R factor. R factors must be positive numbers. A negative
value will cause a configuration error.
SignalFilter[x] 0-3 INT
Designates whether channel 0 uses the analog filter
0 = do not use analog or digital filter
1 = use digital filter (25kHz)
2 = use both digital (25kHz) and analog (12kHz) filters
3= use digital (25kHz), analog (12kHz), and debounce filter (30Hz)
NOTE: The digital and analog filters are separate entities which are
combined into the same tag on this module. The debounce filter
debounces the input for 35 to 40msec after the input transitions.
GateFilter[x] 0,1 INT
0 = No filter
1 = Debounce filter.
The debounce filter debounces the input for 35 to 40msec after the input
transitions.
RollOverTo[x] 0,1 BOOL (C)
Designates which value channel 0 will roll-over to:
0 = zero
1 = preset
RollUnderTo[x] 0,1 BOOL (C)
Designates which value channel 0 will roll-under to:
0 = normal (max value)
1 = preset
Stoponzero[x] 0,1 BOOL (C)
Designates what channel 0 will do when it counts down to 0.
0 = roll-under
1 = stop at zero
Stoponlimit[x] 0,1 BOOL (C)
Designates what channel 0 will do when it counts up to the count_limit.
0 = rollover
1 = stop at the limit
