Appendix 2 QnA/A Series Module

This section explains a comparison of the functions of the Q series C24 and QnA/A

series modules, and explains how to utilize programs created for A series modules as

well as how to install the Q series C24 into the existing system.

QnA/A modules refer to the following products.

Model name Product name

QC24N AJ71QC24N (-R2,R4), A1SJ71QC24N (-R2)

QC24 AJ71QC24 (-R2,R4), A1SJ71QC24 (-R2)

UC24, C24-S8 AJ71UC24, A1SJ71UC24 (-R2,R4,PRF), AJ71C24-S8

Appendix 2.1 Functional Comparison with the Q series C24 and the QnA/A Series Modules

The following shows a functional comparison between the Q series C24 and the

QnA/A series modules.

The

symbol in the model name columns indicates that the corresponding functions

are compatible between the applicable models (for more information, see the manual

for each module).

Indicates functions that have been added to or modified from the QnA/A

series modules.
