Powering Off Or Resetting The Plc - Mitsubishi Electric GOT2000 Series Connection Manual

8.4.5

Powering OFF or resetting the PLC

■1. When turning OFF or resetting the PLC during monitoring
When turning OFF or resetting the PLC during monitoring, the system alarm (No.402: timeout error) is generated.
When the PLC CPU is restored, the GOT automatically resumes monitoring.
Use System Information to reset the alarm.
For the System Information, refer to the following manual:

GT Designer3 (GOT2000) Screen Design Manual
■2. When turning OFF or resetting the PLC CPU before display of the user creation screen
When the PLC CPU is turned OFF or reset before the user creation screen is displayed on the GOT, subsequent
communications may be no longer possible.
In such a case, reapply the power to the PLC CPU and GOT.
■3. Precautions for connection of 3 GOTs or more (when connecting QCPU (Q mode))
➠ 8.4.10 ■1. Restrictions in overall cable length to No. of GOTs
8.4.6 Position of the GOT
Always connect the GOT to the last base unit.
Connecting a GOT between base units is not allowed.
8.4.7 When the GOT is bus-connected to a PLC CPU without the
communication driver written
When the GOT is bus-connected to a PLC CPU without the standard monitor OS and the communication driver for the bus
connection being written onto the GOT, the PLC CPU is reset. (GX Developer cannot communicate with the PLC CPU)
In this case, disconnecting the bus connection cable from the GOT will cancel the reset status of the PLC CPU.
8.4.8 When designing the system
When the GOT is OFF, the following currents are supplied to the GOT from the PLC CPU side (the power supply module on
the main base unit).(The GOT does not operate when it is OFF.)
Design the system so that the 5V DC current consumption of the modules on the main base unit and the total current
consumption of the GOTs will not exceed the rated output current of 5V DC of the power supply module in use.
