Self-diagnostic
error set by
F148 (ERR)
instruction
Description
Probably an abnormality in
the memory (EPROM) or
master memory (EEPROM).
Probably an abnormality in
the system register.
Probably a hardware
abnormality or an abnormality
caused by noise.
Probably a hardware
abnormality or an abnormality
caused by noise.
Probably an
INT
(interrupt)
program corresponding to the
trigger is missing.
Probably an abnormality was
detected when a high-level
or basic instruction was
executed.
The voltage of the backup
battery dropped or the backup
battery has been pulled out
from the holder.
• The self-diagnostic error code specified by the
F148 (ERR)
instruction is transferred to DT9000.
• The contents of the self-diagnostic error code can be
confirmed using the following programming tools.
- NPST-GR Software: “7. STATUS DISPLAY” in
ONLINE mode
- FP Programmer
II
: “OP-110”

Program execution
when an error occurs
Program the memory (EPROM)
or master memory (EEPROM)
again and try to operate. If the
same error is detected, try to
operate with another memory
(EPROM) or master memory
(EEPROM) .
Set the mode of FP-M to PROG.
and initialize the system register.
Turn OFF the power of the FP-
M and check the surrounding
noise level.
Turn OFF the power of the FP-
M and check the surrounding
noise level.
Set the mode of FP-M to
PROG. and make an
INT
program which corresponds to
the interruption.
Check the contents of special
data registers (DT9017 and
DT9018) to find the program
address where the operation
error occurred. Then correct the
program referring to the
description of the instruction.
Replace the backup battery.
The operation without backup
battery can be specified by
system register 4.
System register 4 settings
K0: The conditions are
regarded as errors.
K1: The conditions are not
regarded as errors.
System register 26 settings
K0: FP-M stops operation if an operation error occurs.
K1: FP-M continues operation even if an operation error occurs.
