ALM_CLR: 06H (Clear Alarm or Warning Command)
The ALM_CLR command is used to clear the alarm or warning state. The command can be used in communication
phases 2 and 3.
This command changes the state of a slave station, it does not remove the cause of a fault. After the cause of the alarm or
warning has been removed, this command is then used to clear the status of the alarm or warning.
SYNC_SET: 0DH (Start Synchronous Communication Command)
The SYNC_SET command is used to start synchronous communications. After this command is issued, synchronous
communications are carried out. If communications become asynchronous due to any fault such as a communications
fault, this command can be used to restore synchronous communications. The command can be used in communication
phases 2 and 3. Watchdog data error detection commences when this command has been completed.
