2.3 Precautions
7 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.
8 When assigning GOT I/O signals
Do not use the I/O signals assigned to the PLC CPU in sequence programs, as these signals are used
by the GOT system.
When these signals are used, GOT functions cannot be assured.
9 When connecting to a QCPU (Q mode)
(1) Restrictions in overall cable length to No. of GOTs
The following restrictions apply when 3 of more GOTs are connected:
(2) When using a Q00JCPU
The bus extension connector box can be connected only to the extension base unit.
(Connecting it to the main base unit is not allowed.)
When connecting to No. of GOTs Total current consumption

supply for the PLC and
all GOTs, and turn these
devices ON and OFF
simultaneously.
