C082
H
The communication process was abnormally ended in the
following communications.
• Communications with a programming tool (UDP/IP)
• CC-Link IE Controller Network, CC-Link IE Field
Network, MELSECNET/H, MELSECNET/10 relay
communications
• Check if the relay station/connected station is operating
normally. (If the communication is alive, no action for this
error is required.)
• Check if there is an error with the cable connection
between the own station and the connected station.
• If the line is heavily loaded, reduce the load.
• Increase the number of resends for the data link
instructions.
• Increase the time reserved for the communication process
in the service processing setting in "PLC System" under
"PLC Parameter".
C083
H
The communication process was abnormally ended in
communications using data link instructions.
• Check if the relay station/connected station is operating
normally. (If the communication is alive, no action for this
error is required.)
• Check if there is an error with the cable connection
between the own station and the connected station.
• If the line is heavily loaded, reduce the load.
• Increase the time reserved for the communication process
in the service processing setting in "PLC System" under
"PLC Parameter".
C084
H
The communication process was abnormally ended in
communications using data link instructions.
• Check if the own station/relay station/connected station is
running normally.
• Check if there is a problem with the cable connection
between the own station and the connected station.
• Increase the TCP resend timer value.
• Increase the time reserved for the communication process
in the service processing setting in "PLC System" under
"PLC Parameter".
C085
H
The own station's channel specified by another station in
communications using data link instructions is currently in
use.
• Execute the request from another station again.
C086
H
A message exceeding the receive message size was
received.
• Correct the send message size of the request source.
C087
H
There is an error in the IP address set in the Station No. <-
> IP information setting for CC-Link IE Controller Network,
CC-Link IE Field Network, MELSECNET/H,
MELSECNET/10 relay communications.
• In the Station No.<->IP information setting, set the IP
addresses for the CC-Link IE Controller Network, CC-Link
IE Field Network, MELSECNET/H, and MELSECNET/10
relay communication target devices.
C0B2
H
There is no insufficient space in the receive buffer of the
relay station PC number for MELSOFT connection or data
link instructions, or the communication request destination
station. (Receive buffer full error)
• Increase the request interval.
• Decrease the number of request nodes.
• Wait for a response to the previous request before
sending the next request.
• Correct the timeout value.
C0B3
H
A request that cannot be processed was issued from the
programmable controller CPU.
• Correct the request details.
• Correct the network number or PC number.
C0B5
H
Data that cannot be processed by the programmable
controller CPU or Ethernet module was specified.
• Correct the request details.
• Cancel the current request.
C0B6
H
The channel number is outside the allowable range. • Specify the channel number from 1 to 8.
C0B7
H
A channel number currently in use was specified.
• Change the channel number.
• Perform communications again after the current
communications are completed.
C0B8
H
• The network number or PC number is outside the
allowable range.
• A response from the programmable controller CPU is
faulty.
• Correct the network number or PC number.
• Check the programmable controller CPU operation.
