18.6 Device Range that Can Be Set
For details of the device range that can be used on the GOT, refer to the following.
2.3 MELSEC-QnA/Q/QS, MELDAS C6 *
18.7 Precautions
18.7.1 Direct connection to CPU
Version of CNC
For MELDAS C6/C64, use NC system software version
D0 or later.
18.7.2 MELSECNET/10 connection
Network configuration
Use the MELSECNET/10 mode of MELSECNET/H
(PLC to PLC network) or MELSECNET/10 (PLC to PLC
network) to configure a network including the GOT.
(1) The following networks including the GOT cannot be
configured.
• MELSECNET/10 (Remote I/O network)
• MELSECNET/H (Remote I/O network)
(2) When configuring the network (MELSECNET/H
(PLC to PLC network) including the GOT, refer to the
following.
9. MELSECNET/H CONNECTION (PLC TO
PLC NETWORK)
Monitoring range
Only CNC of the same networks No. can be monitored
in GOT.
For details, refer to the following manual.
3.1 Access Range for Monitoring Stations on
Network Systems
Starting GOT with CNC connection
(MELSECNET/10 connection)
With the CNC connection (MESLSECNET/10
connection), the data link starts approximately 10
seconds after the GOT starts.
When a network error occurs in the system
alarm
When a system alarm regarding a network error occurs
with the CNC connection (MELSECNET/10
connection), the system alarm is kept displaying on the
GOT even though the error factor is removed.
To cancel the system alarm display, restart the GOT.
Version of CNC
For MELDAS C6/C64, use NC system software version
E0 or later.
18.7.3 CC-Link (ID) connection
Using cyclic transmission
(1) I/O signal for master station
Do not turn on the reserved output signals in the output
signals (remote output: RY) to the GOT from the master
station.
When the reserved output signal is turned on, the CNC
system may be malfunctioned.
For the assignment of I/O signals in the GOT, refer to
the following manual.
MODEL GT15-J61BT13 CC-Link
communication unit User's Manual
GT15 CC-Link communication unit User's
Manual
(2) CC-Link Mode
CNC is not compatible with CC-Link Ver.2.
(3) When GOT malfunctions
The cyclic output status remains the same as before
becoming faulty.
For transient transmission
(1) Access range that can be monitored
The GOT can access to the CNC mounting the master
and local station of the CC-Link System.
It cannot access another network via the CC-Link
module.
GOT startup in CNC connection (CC-Link
connection (intelligent device station))
In the CNC connection (CC-Link connection (intelligent
device station)), the data link is started approximately
10 seconds after the GOT startup.
When a network error occurs in the system
alarm
In the CNC connection (CC-Link connection (intelligent
device station)), when a network error occurs in the
system alarm, the system alarm message cannot be
canceled even though the causes are removed.
To cancel the system alarm display, restart the GOT.
Version of CNC
For MELDAS C6/C64, use NC system software version
D0 or later.
