NX Error Clear
The Sysmac Error Clear provides the clear feature of the error status. It is defined as an Unsigned16,
as bits.
Use the following sequence to resolve errors and clear the Sysmac error status:
1. Read error status (from Communication Coupler unit status and/or NX Unit error status).
2. If an error occurred investigate the cause and remove the error condition.
3. Before issuing the error clear command, confirm the state of the "Sysmac Status Clear Capable" flag.
This is bit 13 of the Unit Status as explained above.
Wait for this bit to be 1 and set the Sysmac Error Clear (bit 0) to 1.
4. Issuing the Sysmac Error Clear will set the Sysmac Status Clear Capable (Unit Status bit 13) to 0.
Wait for this bit to be set back to 1.
This confirms the error clear operation succeeded.
