19.1 Error Codes When a Module Error Occurs
Action
Correct the IP addresses of the slave stations.
• 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.
• Check and change the send data size of the CC-Link IE TSN-equipped
module or the external device.
• If the same error occurs again even after taking the above, the possible
cause is a hardware failure of the error module or CPU module. Please
consult your local Mitsubishi representative.
Set "Network Synchronous Communication" for the corresponding local
station to "Asynchronous" in "Network Configuration Settings" under "Basic
Settings" of the master station.
Set "Station-specific mode setting" for the corresponding local station in
"Network Configuration Settings" under "Basic Settings" of the master
station such that it matches that of the local station.
Write the module parameter to the CPU module again. If the same error
occurs again even after taking the above, please consult your local
Mitsubishi representative.
Remove devices with time synchronization priority of 0 to 15, or change the
priority to between 16 and 255.
• Reduce the total number of stations to 31 stations (master station: 1, slave
station: 30) or less.
• Reduce the number of CC-Link IE TSN Class B devices to eight or less for
each port of the master station.
Set a line topology or star topology, and turn off and on or reset all stations.
