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.

(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.

(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.

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.
