Error Indication
How to check address of problem unit
If an error occurs, switch the transmission mode to the CHECK mode. In this mode, you can identify the address
of the problem unit.
Operation of error indicator after detecting error
1. If an I/O unit is disconnected:
The address display of the
SL-VGU1-D
will display ‘E-3’ (error 3), and the error indicator will light up.
<Example 1>
SL-VGU1-D
0
16 32 48
64 80 96 112
End unit
Disconnected
2. If an I/O unit is added:
The address display of the
SL-VGU1-D
will display ‘E-4’ (error 4), and the error indicator will light up.
<Example 2>
SL-VGU1-D
0
16 32 48
64
80 96 112
End unit
Added
3. If the above-described errors 1 and 2 are detected:
The address display of the
SL-VGU1-D
will display ‘E-3’ (error 3) or ‘E-4’ (error 4), and the error indicator will
light up.
* If two or more errors are detected at almost the same time, the address display will indicate the error num-
ber detected first.
