When Designing The System; When Assigning Got I/O Signals; When Connecting To A Qcpu (Q Mode) - Mitsubishi Electric GT1685 Connection Manual

5.4.8

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.

5.4.9 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.
5.4.10 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:

(3) When using a Q00J/Q00UJ/Q00/Q00U/Q01/Q01U/
Q02UCPU
When a GOT is bus-connected to a Q00JCPU or
Q00UJCPU, number of extension stages including the
GOT must be 2 or less.
When a GOT is bus-connected to a Q00CPU,
Q00UCPU, Q01CPU, Q01UCPU or Q02UCPU,
number of extension stages including the GOT must be
4 or less.
