(c)
Processing at detection of faulty remote module
1) If communication is stopped due to faulty remote
module, outputs of the modules are
as
follows:
a)
A2C
I/O
module:
OFF
b) Remote
I10
module for MINI-S3: Depends on
EC
mode
2)
The output state
as
obtained by running the sequence
program is restored by removing the error cause
in
the
faulty station and by resetting the A2C with the RUN key
switch or changing the operation status of the A2C from
STOP to RUN.
(d) Processing
at
an occurrence of transmission underrun
error
1) If the transmission underrun error occurs, data com-
munication stops. In this case, outputs of the module
are
as
indicated below.
a)
A2C
I/O
module:
OFF
b) Remote
I/O
module for MINLS3: Depends on
EC
mode
2)
Communications
start
when the following operation is
carried out.
a)
Turn
OFF
the power to the A2C and turn it back
ON.
b) Reset the A2C.
c)
Change the operation mode from STOP to RUN.
(e)
Processing at an occurrence
of
receive underrun error
1)
If
receive underrun error occurs, the same processing
as
executed at an occurrence of disconnected
line
error
is
executed.
2)
Communications start when the following operation
is
carried out.
a)
Turn
OFF
the power to the A2C
and
turn
it
back ON.
b) Reset the A2C.
c) Change the operation mode from STOP to RUN.
(3)
Remote terminal error
The remote terminal error indicates an error in which com-
munications between the A2C and
a
remote terminal con-
nected to the A2C cannot be executed correctly.
If
the remote
terminal error, with
an
exception of the initial setting error,
occurs, the M9060 is
set
and the error code is stored in D9180
to D9193.
Remove the cause of
the
error for the faulty terminal module.
