ItpWriteToolDescEx
The function block ItpWriteToolDescEx writes a block of tool parameters.
VAR_INPUT
VAR_INPUT
bExecute : BOOL;
nDNo : UDINT;
tTimeOut : TIME;
END_VAR
bExecute: The command is triggered by a rising edge at this input.
nDNo: D-word for which the tool parameters are to be read. nDNo can have values between 1 and 255.
tTimeOut: ADS Timeout-Delay
VAR_IN_OUT
VAR_IN_OUT
sNciToPlc : NCTOPLC_NCICHANNEL_REF;
sToolDesc : ToolDesc;
END_VAR
sNciToPlc: The structure of the cyclic channel interface from the NCI to the PLC. This structure is only accessed for reading. (type: NCTOPLC_NCICHANNEL_REF)
sToolDesc: The structure that contains the new tool parameters. This structure is only accessed for reading. The meaning of the parameters depends on the tool type, and can be found in the tool data.
TYPE ToolDesc:
STRUCT
nToolNumber : UDINT; (*valid range from 0 .. 65535*)
nToolType : UDINT;
fParam : ARRAY [2..15] OF LREAL;
END_STRUCT
END_TYPE
VAR_OUTPUT
VAR_OUTPUT
bBusy : BOOL;
bErr : BOOL;
nErrId : UDINT;
END_VAR
bBusy: This output remains TRUE until the function block has executed a command, but at the longest for the duration supplied to the 'Timeout' input. While Busy = TRUE, no new command will be accepted at the inputs. Please note that it is not the execution of the service but its acceptance whose time is monitored.
bErr: This output is switched to TRUE as soon as an error occurs during the execution of a command. The command-specific error code is contained in ‘nErrId’. Is reset to FALSE by the execution of a command at the inputs.
nErrId: Contains the command-specific error code of the most recently executed command. Is reset to 0 by the execution of a command at the inputs. The error numbers in ErrId can be looked up in the ADS error documentation or in the NC error documentation (error codes above 0x4000).
