■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, 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
