Parameter Manager¶
Description¶
The parameter manager is responsible for the saving of parameters in the permanent memory of the device. On startup, all stored parameters are read from permanent memory; if parameters are changed, the data is stored within the permanent memory by the parameter manager.
All data is protected with a CRC32 checksum. In the event of damaged memory, the parameter manager outputs the Parameters not consistent event.
If this error only affects parameters which can be restored, the memory is repaired directly by the device. In this case all set data is reset to the default settings and the device signals this state via a warning.
Acknowledge warning
- Check set data.
- Acknowledge warning by sending the system command 0xC1- Acknowledge User Parameters Reset to the device.
Data can be very easily restored via the IO-Link parameter server (see Data Storage).
System Commands¶
| Command Value | Device Action |
|---|---|
| 0xC1 (193) | Acknowledge User Parameter Reset – Acknowledge message and restore the correct device parameters. |
Events¶
