ItpSetCyclicUDintOffsets
The function block ItpSetCyclicUDintOffsets is used to describe the cyclic channel interface for the 4 freely configurable UDINT variables. Variables (index offsets) can be selected from the group state.
The functionality is only active if nIndexOffsetParam1 is not equal 0.
Inputs
VAR_INPUT
bExecute : BOOL;
tTimeOut : TIME;
nIndexOffsetParam1 : UDINT;
nIndexOffsetParam2 : UDINT;
nIndexOffsetParam3 : UDINT;
nIndexOffsetParam4 : UDINT;
END_VAR
Name | Type | Description |
---|---|---|
bExecute | BOOL | The command is triggered by a rising edge at this input. |
tTimeOut | TIME | ADS Timeout-Delay |
nIndexOffsetParam1 | UDINT | Group state (Index Offset) for parameter 1 |
nIndexOffsetParam2 | UDINT | Group state (Index Offset) for parameter 2 |
nIndexOffsetParam3 | UDINT | Group state (Index Offset) for parameter 3 |
nIndexOffsetParam4 | UDINT | Group state (Index Offset) for parameter 4 |
/ Inputs/Outputs
VAR_IN_OUT
sNciToPlc : NCTOPLC_NCICHANNEL_REF;
END_VAR
Name | Type | Description |
---|---|---|
sNciToPlc | NCTOPLC_NCICHANNEL_REF | The structure of the cyclic channel interface from the NCI to the PLC. This structure is read-only (type: NCTOPLC_NCICHANNEL_REF). |
Outputs
VAR_OUTPUT
bBusy : BOOL;
bErr : BOOL;
nErrId : UDINT;
END_VAR
Name | Type | Description |
---|---|---|
bBusy | BOOL | 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 | BOOL | 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 | UDINT | 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). |
