Precautions - Mitsubishi Electric GOT2000 Series Connection Manual

11.5 Precautions

■1. GOT startup in CC-Link IE Field Network connection
For the CC-Link IE Field Network connection, the data link is started approximately 15 seconds after the GOT startup.
■2. When a network error occurs in the system alarm
In the CC-Link IE Field Network connection, when a network error occurs in the system alarm, the system alarm
display cannot be canceled even though the causes are removed.
To cancel the system alarm display, restart the GOT.
■3. CC-Link IE Field Network module version
For version restrictions of the CC-Link IE Field Network module, refer to the following manual.
➠
■4. Connection to Q170MCPU or Q170MSCPU(-S1)
The Motion CPU area (CPU No.2) cannot be monitored.
Set the CPU No. to "0" or "1".
The device of the PLC CPU area (CPU No.1) is monitored.
For setting the CPU No., refer to the following manual.
➠
Example) Setting dialog box of the bit device
■5. 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.
➠
■6. 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.
