Error list of MELSEC data link function HELP
Since a timeout has occurred in communication with the target,
retry (e.g. Start monitoring, Device settings) after checking the
following.
• Check if the target C Controller module is operating.
• Check if the Ethernet cable is connected.
• Check if the specified IP address or host name is correct.
• Using the C Controller setting utility, set the priority setting of
the utility communication task to a smaller value or default.
( Section 9.2.6 (2)(d))
• Check the line state.
If the line is congested, a communication error (timeout error)
tends to occur (monitoring tends to stop).
• Check the monitor performance state.
If other station access (e.g. access via CC-Link module and
MELSECNET/H module) is frequently performed, a
communication error (timeout error) tends to occur.
Since installation of SW PVC-CCPU may have failed, reinstall
it.
