Precautions - Mitsubishi Electric GT1685 Connection Manual

13.5 Precautions


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 PLC
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) Access range that can be monitored
The monitoring range of remote I/O (RX and RY) and
that of the remote registers (RWr and RWw) vary
according to the mode in the master station of the CC-
Link system.
Data for each station

: Applicable
*1 Monitoring is applicable only when MODEL GT15-J61BT13
CC-Link communication unit is used.
(3) When GOT malfunctions, the cyclic output status
remains the same as before becoming faulty.

For transient transmission
(1) CC-Link module of target station
Mount the CC-Link module of function version B or later
and software version J or later to the PLC CPU when
performing the following CC-Link modules and
transient transmission.
Only cyclic transmission can be communicated with the
CC-Link module of function version A or before and
software version I or before.
• AJ61BT11
• A1SJ61BT11
• AJ61QBT11
• A1SJ61QBT11
(2) Access range that can be monitored
The GOT can access to the PLC CPU mounting the
master and local station of the CC-Link System.
It cannot access another network via the CC-Link
module.


GOT startup in the CC-Link connection
(intelligent device station)
For 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 CC-Link connection (intelligent device station),
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.

Connection in the multiple CPU system
When the GOT is connected to multiple CPU system,
the following time is taken until when the PLC runs.
QCPU (Q mode), motion controller CPU (Q series): 10
seconds or more
MELDAS C70: 18 seconds or more
When the GOT starts before the PLC runs, a system
alarm occurs.Adjust the opening screen time in the
GOT setup so that no system alarm occurs.

Manual

Connection to LCPU
LCPU may diagnose (check file system, execute
recovering process, etc.) the SD memory card when
turning on the power or when resetting. Therefore, it
takes time until the SD memory card becomes
available. When the GOT starts before the SD card
becomes available, a system alarm occurs. Adjust the
opening screen time in the GOT setup so that no
system alarm occurs.


Connection to Q17nDCPU, Q170MCPU,
CNC C70, CRnQ-700
The Q17nDCPU, Q170MCPU, CNC C70 and CRnQ-
700 are applicable to the CC-Link network system Ver.2
only
For connecting to the CC-Link (ID) network system, set
the CC-Link (ID) network system to the CC-Link Ver.2
mode.
