10.5 List of Error Codes
Action
Correct the CPU type of the target station at the request source of the
dedicated instruction, and retry the operation.
• Correct the arrival monitoring time at the request source of the dedicated
instruction, and retry the operation.
• When the own station, target station, or relay station detected an error,
identify the cause of the error and take action.
• Lower the transient transmission usage frequency, and retry the
operation.
• Check if the switching hub and the Ethernet cables at the request source
are connected properly.
• Correct the number of resends at the request source of the dedicated
instruction, and retry the operation.
• When the own station, target station, or relay station detected an error,
identify the cause of the error and take action.
• Lower the transient transmission usage frequency, and retry the
operation.
• Check if the switching hub and the Ethernet cables at the request source
are connected properly.
Correct the network number at the request source of the dedicated
instruction, and retry the operation.
• Set 1 to 2 for the target channel number in the control data when
executing the SEND instruction.
• Correct the number of the channel used by own station in the control data,
and retry the operation.
• The value set for the control block of the dedicated instruction is out of
range. Correct the value and retry the operation.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
• Specify the station number/IP address using the UINI instruction, and
execute the instruction again.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
• Execute again after changing the execution type in the control data to no
arrival check.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
• Check the network status using the CC-Link IE TSN/CC-Link IE Field
diagnostics of the engineering tool, and take action.
• For IP address specification, it is not possible to target stations beyond a
relay station. Execute the dedicated instruction by specifying the network
number/station number.
• Increase the number of resends at the request source of the dedicated
instruction, and retry the operation.
• Lower the transient transmission usage frequency, and retry the
operation.
• Execute the dedicated instruction for a target station that supports the
executed dedicated instruction.
• For the RECV instruction, correct the channels used by own station in the
control data, and retry the operation.
• For the RECV instruction, check that 'RECV execution request flag CH1'
(SB0030) to 'RECV execution request flag CH8' (SB0037) are on.
• Correct the network number and station number/IP address of the target
station of the dedicated instruction.
• Check if the Ethernet cable is disconnected.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
• Change the target station at the station that executed the SEND
instruction.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
• Correct the target station number in the control data, and retry the
operation.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
