Precautions

■1. Time taken until the PLC runs when connected in the multiple CPU system

The following time is taken until the PLC runs.

MELSEC iQ-R series, motion controller CPU (MELSEC iQ-R series), 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.

■2. Connection to LCPU

LCPU may diagnose (check file system, 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.

■3. When monitoring the Q170MCPU

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.

Example) Setting dialog box of the bit device

■4. Connection to RnSFCPU

The RnSFCPU takes 10 seconds or more to run.

If the GOT is started before the RnSFCPU runs, a system alarm occurs.

To prevent a system alarm from occurring, adjust the title display time in the [GOT Setup] dialog.
