2.3 Precautions
10 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.
