mekiFunction

Cmpr

Cmpr is used to compare two input values.

Parameters:

• Xgy (boolean) – true when X is greater than Y, else false

• Xey (boolean) – true when X is equal to Y, else false

• Xly (boolean) – true when X is less than Y, else false

• X (real) – Input value

• Y (real) – Input value

Count

Count is used to count the transistion of a boolean value from false to true.

Parameters:

• Out (integer) – Number of times In has transitioned from false to true

• In (boolean) – Input value

• Present (integer) – Presets the counter to a specific value, defaults to 0

• Dir (boolean) – Count direction, true for up while false for down

• Enable (boolean) – To enable In counting

• Reset (boolean) – If true, out = preset and no counting. It act as a reset switch

Freq

Freq is used to calculate the changing frequency of a boolean value.

Parameters:

• Pps (real) – The changes in the frequency per second

• Ppm (real) – The changes in the frequency per minute

• In (boolean) – Input value

Hysteresis

Hysteresis can output a boolean value according to thier rising edge and falling edge limit.

Parameters:

• In (real) – Input value

• Out (boolean) – Output value

• Rising_Edge (real) – Rising edge limit, Out become true when In greater than it

• Falling_Edge (real) – Falling edge limit, Out become false when In less than it

IRamp

IRamp provides linear ramping output based on time set.

Parameters:

• Out (integer) – Output value

• Min (integer) – Start value of the ramping

• Max (integer) – End value of the ramping

• Delta (integer) – Value change every time

• Secs (integer, second) – Time intervals very time change

Limiter

Limiter limits the output according to the upper limit and lower limit.

Parameters:

• Out (real) – Output value

• In (real) – Input value

• lowLmt (real) – Lower limit for Out

• highLmt (real) – Upper limit for Out

Linearize

Linearize defines 8 sets of corresponding data, and calculate the output value according to the input value with linearization data.

Parameters:

• Out (real) – Output value

• In (real) – Input value

• x0-x9 (real) – Range for In

• y0-y9 (real) – Range of converted Out

Ramp

Ramp provides a triangle or sawtooth type ramping output.

Parameters:

• Out (real) – Output value

• Min (real) – Minimum value of the ramping Out

• Max (real) – Maximum value of the ramping Out

• Period (integer, second) – The time for one complete Min / Max in second for ramp Out, range from 0 to 65535

• ScanPeriod (integer, millisecond) – The time for Out updating interval, range from 100 to 65535

• RampType (option) – Ramp type, triangle or sawtooth

SRLatch

SRLatch keeps output value to true as long as the set value is true, until the reset is triggered.

Parameters:

• Out (boolean) – Output value

• Set (boolean) – Triggers to set Out to true

• Reset (boolean) – Triggers to restore Out back to false

TickTock

TickTock outputs true and false values alternately according to the frequency

Parameters:

• Out (boolean) – Constantly change between true and false

• TickPerSec (integer) – Change frequency of Out, range from 1 to 10

UpDn

UpDn records the changes of the input value, the record number can be documented in increasing or reducing order. The records can be reset too.

Parameters:

• Out (real) – Output Value

• Ovr (boolean) – true when Out is greater than Limit

• In (boolean) – Input Value

• Rst (boolean) – Triggers to restore Out to 0

• CDwn (option) – The trend of recorded Out, either Up or Down

• Limit (real) – Limits Out when HoldAtLimit is true

• HoldAtLimit (boolean) – Enable the Limit function
