Troubleshooting
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.
Note
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.
