error
• Stores error code when M9061 is turned on
(communication with I/O modules or remote terminal
modules fails).
• 1 .......Total number of stations of I/O modules or
remote terminal modules or number of retries is
not normal. Initial program contains an error.
• 2 .......Cable breakage or power supply of I/O modules
or remote terminal modules is turned off.
• 3 .......When the "Transmission stop at online error
mode is selected, a faulty station occurs.
• 4 .......Transmission underrun of the MINI link occurs.
• 5 .......A watchdog timer error occurs on the master
module in the MINI link network.
