AL Status

The ALStatus property returns any errors at the start of the stack. For example, configuration errors at the slave instance are displayed.

Tip

The AL status messages are also recorded in the logger.

Error codes

Value	Error Text	Comment
16#0	No error
16#1	Unspecified error
16#2	No memory
16#11	Invalid requested state change
16#12	Unknown requested state
16#13	Bootstrap not supported
16#14	No valid firmware
16#15	Invalid mailbox configuration	The configuration is not accepted by the device because, for example, data from the ESI file does not match the device.
16#16	Invalid mailbox configuration
16#17	Invalid sync manager configuration
16#18	No valid inputs available
16#19	No valid outputs
16#1A	Synchronization error	The DC settings may be incorrect.
16#1B	Sync manager watchdog	Interruption in the connection, for example due to a brief disconnection of the cable, or the PLC has been stopped.
16#1C	Invalid sync manager types
16#1D	Invalid output configuration	The configuration is not accepted by the device because, for example, data from the ESI file does not match the device.
16#1E	Invalid input configuration	The configuration is not accepted by the device because, for example, data from the ESI file does not match the device.
16#1F	Invalid watchdog configuration
16#20	Slave needs cold start	Switch device off and back on
16#21	Slave needs INIT

16#2A	Background watchdog
16#2B	No valid inputs and outputs
16#2C	Fatal Sync error
