Powering OFF the GOT,
reapplying the power (OFF to
ON)
(1) Precautions for reapplying the power to the GOT
(OFF to ON)
Do not power-cycle the GOT (OFF to ON) while the
PLC is ON.
Before doing so, be sure to turn off the PLC first.

Operations causing automatic reboot of the GOT1000
Series
Since the GOT1000 Series is automatically rebooted
in the following cases, the power does not need to be
reapplied to the GOT (OFF to ON).
• When an OS is written from GT Designer3 or a CF
card
• When utility settings have been changed
(2) When turning OFF the GOT before display of the
user creation screen
When the GOT is turned OFF 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))
5.4.10 (1)Restrictions in overall cable length to
No. of GOTs
5.4.4
Reset switch on GOT
When bus connection is used, the reset switch on the GOT
does not function.
5.4.5
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 Version 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))
5.4.10 (1)Restrictions in overall cable length to
No. of GOTs
5.4.6
Position of the GOT
Always connect the GOT to the last base unit.
Connecting a GOT between base units is not allowed.
5.4.7
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.
