When Assigning Got I/O Signals - Mitsubishi Electric GOT2000 Series Connection Manual

8.4.9

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.
8.4.10 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:
Number
of GOTs
1
2
3
4
5
■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)
■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.
