4.7 Error Codes
Error details and cause
• The extension level setting of the Q
series extension base unit is
overlapping with that of any other
extension base units.
• An error was detected on the system
bus.
An error was detected on the system
bus.
A failure has detected in network
processing.
A failure has detected in network
processing.
The cyclic processing does not finish
before the start timing for the next inter-
module synchronization cycle.
An inter-module synchronization error
has been detected.
An inter-module synchronization error
has been detected.
A station with the same station number
was found in the same network.
Action
• Check and correct the level setting of the Q
series extension base unit.
• Check the connection of an extension cable.
• Check that the 10m mark is printed on the base
unit connected when using the ten-meter
extended cables (RC100B). ( MELSEC iQ-R
Module Configuration Manual)
• Take measures to reduce noise.
• Reset the remote head module, and run it again.
If the same error code is displayed again, the
possible cause is a hardware failure of the
remote head module, base unit, or extension
cable. Please consult your local Mitsubishi
representative.
• Take measures to reduce noise.
• Reset the remote head module, and run it again.
If the same error code is displayed again, the
possible cause is a hardware failure of the
remote head module or base unit. Please
consult your local Mitsubishi representative.
• Check whether the network is incorrectly
configured in a ring topology, and correct the
wiring.
• Take measures to reduce noise.
• If the same error code is displayed again, please
consult your local Mitsubishi representative.
• Check whether the network is incorrectly
configured in a ring topology, and correct the
wiring.
• Take measures to reduce noise.
• If the same error code is displayed again, please
consult your local Mitsubishi representative.
• Increase the value set in "Fixed Scan Interval
Setting of Inter-module Synchronization" under
"Inter-module Synchronous Setting" in the [Inter-
module Synchronous Setting] tab of the "System
Parameter" window so that the link scan time will
not exceed the inter-module synchronization
cycle.
• Reduce the number of cyclic assignment points
and the number of connected slave modules to
decrease the link scan time.
• Take measures to reduce noise.
• Reset the remote head module, and run it again.
If the same error code is displayed again, the
possible cause is a hardware failure of the
remote head module, base unit, extension
cable, or module (I/O module or intelligent
function module) connected. Please consult
your local Mitsubishi representative.
• Check that the remote head module is
connected to the inter-module synchronous
master using the CC-Link IE Field Network
diagnostics of the engineering tool.
• Take measures to reduce noise.
• Reset the remote head module, and run it again.
If the same error code is displayed again, the
possible cause is a hardware failure of the
remote head module, base unit, extension
cable, or module (I/O module or intelligent
function module) connected. Please consult
your local Mitsubishi representative.
Correct the station number or station type of the
station where the error was detected.
After taking the above actions, power off and on or
reset all stations where the error was detected.
