5.4.8When 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.

5.4.9When 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.

(2)When using a Q00JCPU, Q00UJCPU

The bus extension connector box can be connected only to the extension base unit.

(Connecting it to the main base unit is not allowed)

Q00UJCPU

(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.
