Mitsubishi Electric MELSEC-Q Series - Chapter 2 Replacement of Cpu Module; List of Alternative Models of CPU Module

2 REPLACEMENT OF CPU MODULE
2 - 1
The following is an example of alternative Q series CPU modules that can be chosen based on
compatibility with previous AnS/QnAS series CPU. The optimal AnS/QnAS series replacement may be
selected based on type of control, specifications, system scalability and cost.
