5.5

Precautions

■1. Connection to QnA (S) CPU type
Use B or a later function version of Ethernet module (QnA Series) and PLC CPU (QnA/QnASCPU type).
■2. Connection to QSCPU
The GOT can only read device data and sequence programs by the ladder monitor function in the QSCPU.
The GOT cannot write any data to the QSCPU.
■3. Connection to Q170MCPU or Q170MSCPU(-S1)
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 "1", the device on the PLC CPU area (CPU No.1) is monitored.
When the CPU No. is set to "0", the monitoring target differs depending on the GOT connection destination. Refer to
the following.
GOT connection destination
QJ71E71 module
Q170MCPU,Q170MSCPU(-S1)
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.
➠ GT Designer3 (GOT2000) Screen Design Manual
Example) Setting dialog box of the bit device
■4. 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.
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.
