A recapitulative table:
Class 1 errors:
fatal errors
Class 2 errors:
serious errors
Class 3 errors:
light errors
Class 4 errors:
warnings
Detection:
Immediate
Immediate
- Bus error: if the central
unit detects a frame
control error (CRC) during
9 successive cycles
or a timing error
or the absence of a reply
from a unit.
- Cycle timing error: if the
system detects the
overriding of the pre-
defined cycle time after
16 consecutive cycles.
- Unit error: the central unit
queries one slave per cycle.
An error is detected
between 1 and 31 cycles.
- Program syntax error: The
central unit detects this type
of error when passing from
STOP to RUN via the
switch
or via the software
or by on-line validation of a
program modification.
LED status
- on the central unit:
ERR led on
RUN led off even if the
RUN/STOP switch is on
RUN
ERR led on
RUN led off even if the
RUN/STOP switch is on
RUN
ERR led on
According to the
configuration, the RUN
led is off even if the
RUN/STOP switch is on
RUN
ERR led on
Following a program syntax
type error, the RUN led is
off.
- on the extensible
remote units :
ERR led on or flashing
according to the case
ERR led on
- on the extensions:
Flashing SUPPLY led
Flashing SUPPLY led
- on non-extensible
remote units:
Error led on or flashing
according to the case
Error led on
Reaction while powering
up or during central unit
usage:
All outputs remain on, or
are set to, 0.
The programming
software no longer has
access to the central
unit.
The central unit remains
on RESET while the
error remains present.
All outputs remain on, or
are set to, 0.
The programming
software retains access
to the central unit.
The user program has
not started or is stopped.
The inputs of a unit on
error retain the old values
for 9 cycles and are then
reset to 0.
The outputs of a remote
unit or extension are reset
to 0.
No program stoppage by
default.
It’s possible to prepare an
automatic program
stoppage with prior
configuration
(see chapter 5)
No program stoppage
Acknowledgment after
error removal:
- Power on
- Power on
- Software cold restart
- Software warm start or
RESET
- Software
acknowledgment
- Switch RUN/STOP from STOP to RUN
- Program launch through software
- Software warm restart
- Software cold restart
- Power on
- Software acknowledgment in the “STATUS” window"
- Acknowledgment through programming
- Test button on the 30 and 90 series remote units
- Automatic
acknowledgment if the error
