*1
The 7-segment indicator will alternate between the Unit's node address and the code given in the tables in this section.
*2
When a (master function) structure error or verification error occurs, only the most recent error is displayed for each slave.
If the Unit is set to stop the remote I/O communications for a communications error, two errors can be displayed: The
slave's communications error and its most recent error.
