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). |
|
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 |
