FiFoOverwrite

The function block FiFoOverwrite reads position data for iColDim FIFO channel axes from AdrDataArray and transfers iRowsToWrite entries to the FIFO. Existing FIFO data will be overwritten.

Inputs

VAR_INPUT
    iChannelId    : UDINT;
    AdrDataArray  : POINTER TO LREAL; (* PLC: ARRAY[ ROWS, COLUMNS ] OF LREAL *)
    iColDim       : UDINT; (* second array dimension (COLUMNS) *)
    iRowsToWrite  : UDINT; (* number of rows to write <= RowDim *)
    bExecute      : BOOL;
    tTimeout      : TIME;
END_VAR

Name	Type	Description
iChannelId	UDINT	Channel ID of the FIFO channel
AdrDataArray	POINTER TO LREAL	The address of a data field containing position data for the master and slave axes. The first of the field's dimensions describes the table lines, and the second dimension describes the columns.
iColDim	UDINT	Number of columns in the data field. This value must correspond to the actual size of the second field dimension.
iRowsToWrite	UDINT	Number of table lines. This value may be less than or equal to the size of the first field dimension.
bExecute	BOOL	Edge-triggered signal for execution of the command
tTimeout	TIME	ADS timeout (about 1 second)

Outputs

VAR_OUTPUT
    bBusy   : BOOL;
    bErr    : BOOL;
    iErrId  : UDINT;
END_VAR

Name	Type	Description
bBusy	BOOL	Becomes `TRUE` with a rising edge at bExecute, and remains `TRUE` until the block has executed the command.
bErr	BOOL	Becomes `TRUE` if an error occurs while executing the command
iErrId	UDINT	Error number (ADS or NC error number)

Requirements

Development environment	Target platform	PLC libraries to be linked
TwinCAT V3.1.0	PC or CX (x86 or x64)	Tc2_NcFifoAxes
