Data link failure in other stations at GOT startup
At GOT startup, the data link failure may occur in other stations.
However, after the failure occurrence, the GOT reconnects automatically and monitors the devices properly.
To avoid such data link failure, start up the GOT 10 seconds earlier than the master station.
However, if the master station does not complete startup when GOT starts monitoring (10 seconds after the GOT startup), the communication timeout occurs in the GOT side.
For details, refer to the following manual.
Data link failure in all stations at GOT startup or cable connection/disconnection
At GOT startup, the communication is broken temporarily between PORT1 and PORT2 in the CC- Link IE Field module which is installed on the GOT. Thus, as the GOT or a station between the GOT and the master station is reconnected, the data link failure may occur on all stations.
POINT
GOT startup
GOT startup indicates the startups after the following operations:
•Turning ON the GOT
•Resetting the GOT main unit
•Operating the utility
•Downloading the project including the communication settings
•Downloading the OS
When the output is required to be held at the data link failure
Set the GOT to hold the input from the data link faulty stations in the communication setting. Set "Input for Error Station" to "Hold".
