When using the QA1S6 B extension base unit
A GOT is physically connected to the last of all extension base units. In the Stage No. setting, however, assign the
GOT as a stage next to the last Q
B type extension base unit.
Assign the QA1S6 B type extension base unit as a stage next to the GOT.
8.4.11 When connecting to a QnA(S)CPU or An(S)CPU type
■1.
When connecting with a QnASCPU type and an AnSCPU type
A GOT can be connected to an extension connector on only one side of the main base unit.
(Concurrently connecting GOTs to extension connectors on both sides is not allowed)
■2.
In the case of Q4A(R)CPU, Q3ACPU, A3 CPU, A4UCPU
Empty I/O slots are required within the max. number of extension stages.
■3. For A0J2HCPU
Assign the GOT to the I/O slots 0 to 3 of extension stage 1.
■4.
In the case of CPUs other than ■ 2. ■ 3. above
Even if the max. number of stages are used with no empty I/O slots, when there is a free space of 32 I/O points or
more, a GOT can be connected under the following communication interface setting.
For the communication interface setting, refer to the following.
