Note
I/O errors can be read out from safety input status, test output status, and
safety output status.
Status data when I/O is normal: ON (1)
Status data when an error occurs I/O: OFF (0)
The details of errors can be read out by using explicit messages and the Net-
work Configurator.
For I/O error latch time settings, the OFF status is maintained for at least the
error latch time (0 to 65,530 ms, in increments of 10 ms) when individual
safety input status turns OFF.
The configuration is invalid.
1. The power source (positive side) is in
contact with the input signal line.
2. Short-circuit between input signal
lines
3. Trouble with the connected device
Trouble with the internal circuits
1. Ground fault or break in an input sig-
nal line
2. Trouble with the connected device
3. The discrepancy time setting is not
satisfied.
Dual channels are set and an error
occurred in the other channel.
