(PLC NETWORK)

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 (Via G4) network system, set the CC-Link (G4) network system to the CC-Link Ver.2 mode.

Set [CPU No.] to "2" in the device setting to monitor the device of the Motion CPU area (CPU No.2).

When the CPU No. is set to "0" or "1", the device on the PLC CPU area (CPU No.1) is monitored.

When the CPU No. is set to the number other than "0" to "2", a communication error occurs and the monitoring cannot be executed.

For setting the CPU No., refer to the following manual.
