ItpSetCyclicLrealOffsets
from library version 6.1.25 and TwinCAT version 2.10 Build 1320
The function block ItpSetCyclicLrealOffsets is used to describe the cyclic channel interface for the 4 freely configurable LREAL variables. Variables (index offsets) can be selected from the group state.
The functionality is only active if nIndexOffsetParam1 is not equal 0.

Input | Data 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 |
Input & output | Data type | Description |
---|---|---|
sNciToPlc | NciChannelToPlc | The structure of the cyclic channel interface from the NCI to the PLC. This structure is only accessed for reading. |
Output |
Data 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). |
