Error
• Check the network status using the CC-Link IE Field Network diagnostics
of the programming tool.
• When the target station is overloaded and cannot receive transient data,
send the data to the target/relay station after the load on the station is
reduced.
• Reduce the frequency of transient transmission, and retry the operation.
• Check if the switching hub and the cables at the request source are
connected properly.
• Reduce the frequency of transient transmission, and retry the operation.
• Check if the switching hub and the cables at the request source are
connected properly.
• Correct the number of link dedicated instructions that is simultaneously
executed within the range. (Refer to Section 10.2.2 (1) (c).)
Correct the number of data (frame length) at the request source, and retry
the operation.
Correct the header information at the request source, and retry the
operation.
Correct the target station number at the request source, and retry the
operation.
Correct the request source number at the request source, and retry the
operation.
Correct the header information at the request source, and retry the
operation.
Correct the target network number at the request source, and retry the
operation.
Correct the target station number at the request source, and retry the
operation.
Correct the network number of the request source at the request source,
and retry the operation.
Correct the station number of the request source at the request source,
and retry the operation.
Correct the number of data (frame length) at the request source, and retry
the operation.
Transient data transmission addressed to the own station was requested.
Check the network number and target station number, and retry the
operation.
• Check if the switching hub and the cables at the request source are
connected properly.
• Reduce the frequency of transient transmission, and retry the operation.
Not support function is executed in the CC-Link IE Field network
diagnostics.
Check the support functions of the simple motion module.
