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 'nTimeout' input. While bBusy = TRUE, no new command will be accepted at the inputs. |
|
bError |
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 ‘nErrorId’. If the function block has a timeout error, 'bError' is TRUE and 'nErrorId' is 1861 (hexadecimal 0x745). Is reset to FALSE by the execution of a command at the inputs. |
|
nErrorId |
ULONG |
Contains the ADS error code or the command-specific error code of the last executed command. Is reset to 0 by the execution of a command at the inputs. |
