BC10ArrFifo
B = Buffer
C = Calculation Functions
The BC10ArrFifo function manages a buffer of first input - first output type. The function requires an input value in the 'ElementIn' variable that is buffered to the required position (through the 'PuntatIn' variable) and slides all values of the buffer until the element indicated by the 'PuntatOut' variable. This value comes from the buffer and ends in the 'ElementOut' variable.
IMPLEMENTATATION
BC10ArrFifo (Buffer, elementIn, elementOut, PuntatIn, PuntatOut)
Parameters:
| IN/OUT | VARIABLE TYPE | EXAMPLE NAME | DIM | |
|---|---|---|---|---|
| IN | ARRSYS | Buffer | B/W/L/S | Array containing the Buffer |
| IN | SYSTEM | ElementIn | B/W/L/S | Var that contains the value to be placed in the buffer |
| IN | SYSTEM | ElementOut | B/W/L/S | Var that contains the value that comes from the buffer |
| IN | SYSTEM | PuntatIn | L | Var that contains the item number of the buffer at which to insert the new value |
| OUT | SYSTEM | PuntatOut | L | Var that contains the buffer element number from which we extract the value |
Ezample
Inserts each according to the count value to a device in the buffer (eliminating the first introduced)
MAIN:
IF tmTimer
tmTimer = 1000
elementIn = count:posit
BC10ArrFifo (BufferS, elementIn, elementOut, PuntatIn,PuntatOut)**
ENDIF
Note
-
If the PuntatIn parameter or PuntatOut parameter is 0, the function take as value, the first element of the buffer and the last element of the buffer.
-
The function executes a WAIT every 150ms.
