(5) Error codes system
MELSEC iQ-R series error codes are expressed with 4 hexadecimal digits (integer without
16-bit sign). There are errors detected with each module's self-diagnostic function, and
common errors detected when communicating between modules.
The error detection types and error code ranges are shown below.
Error detection type
Detection with each module's
self-diagnostic function
Detection when communicating
between modules
Errors detected at the RnMTCPU are divided into warnings and errors. The categories and
error code range of errors detected at the RnMTCPU are shown below.
Category
Warning
Minor
Minor
(SFC)
Error
Moderate
Major
Error code range
H0001 to H3FFF
H4000 to H4FFF
H7000 to H7FFF
HB000 to HBFFF
HC000 to HCFBF
HD000 to HDFFF
HE000 to HEFFF
HF000 to HFFFF
Error code
Warnings which do not stop
H0800 to H0FFF
servo programs
Errors which stop servo
programs
H1000 to H1FFF
The CPU continues to operate
(in RUN status).
Motion SFC execution errors
H3100 to H3BFF The CPU continues to operate
(in RUN status).
H2000 to H30FF
Errors that put the CPU
operation status to "During stop
error".
H3C00 to H3FFF
These are errors such as module self-diagnostic errors
that are different for each module.
CPU module error
Serial communication module error
CC-Link module error
Ethernet module error
CC-Link IE field network module error
CC-Link IE controller network module error
MELSECNET/H network module, MELSECNET/10
network module error
Description
• Equivalent to some of the Q17nCPUN(-T)
minor errors
• Equivalent to some of the minor errors of
Q17nCPUN(-T), and the major errors
• Equivalent to Motion SFC errors of
Q17nCPUN(-T).
• If the system parameter is set to "All
station stop by stop error of CPU No.1 to
4", all CPUs of the whole system will be in
stop status with the specified CPU stop
error.
• Equivalent to system setting errors of
Q17nCPUN(-T).
• If the system parameter is set to "All
station stop by stop error of CPU No.1 to
4", all CPUs of the whole system will be in
stop status with the specified CPU stop
error.
• Equivalent to some of the self-diagnostic
errors of Q17nCPUN(-T).
