Description
execution
Stops Probably a hardware
abnormality.
Stops Probably an abnormality in
the internal RAM.
Stops Probably an abnormality in
the optional ROM.
Stops Intelligent modules
installed exceed the
limitations [e.g., more than
3 standard link modules
(such as MEWNET-P/-W
C-NET or C.C.U.) are
installed on the FP3].
Stops Probably an abnormality in
the system register.
Stops Probably a hardware
abnormality.
Stops Probably a hardware
abnormality.
Stops Interrupt program was
executed even if no
interrupt trigger turned ON.
Probably a hardware
abnormality or an
abnormality caused by
noise.
Stops Interrupt program was
executed even when no
interrupt trigger was turned
ON.
Probably a hardware
abnormality or an
abnormality caused by
noise.
Probably an INT program
corresponding to the
interrupt trigger is missing.
CPU2 Occurs when a FP3 or
stops FP10S is used as CPU2
for a multi-CPU system.
Steps to take
Please contact your dealer.
Please contact your dealer.
Re-make user ROM and try
operating again.
Turn OFF FP-C/FP3/FP5/FP10S/
FP10 power and configure intelligent
modules referring to the hardware
manual or technical sheets for each
CPU.
Set the mode of FP-C/FP3/FP5/
FP10S/FP10 to PROG. and initialize
system registers.
Please contact your dealer.
Please contact your dealer.
Turn OFF FP-C/FP3/FP5/FP10S/
FP10 power and check the
surrounding noise level.
Turn OFF FP-C/FP3/FP5/FP10S/
FP10 power and check the
surrounding noise level.
Set the mode of FP-C/FP3/FP5/
FP10S/FP10 to PROG. and make
an INT program which corresponds
to the interrupt trigger.
Please contact your dealer.
