7-segment LED
The 7-segment LED indicator is on the front panel.
When the power is turned on, it shows the node address that is set by the
rotary switches. Then the indication changes in accordance with the setting
on the Default Display (Pn700). If any alarming error occurs, it indicates the
error number (Errxxx) as the alarm code. If any warning situation occurs, it
indicates the warning number as the warning code.
