Appendix 1 Functional Improvements of the Q Series C24 |
| |
|
| |
|
|
|
The Q series C24 of function version B has several functions that have been added or changed from the conventional product (function version A).
This chapter explains a comparison of the functions of Q series C24/GX Configurator- SC accompanied by the change/addition of functions, and explains how to utilize programs created for function version A as well as how to incorporate function version B modules into the existing system.
Appendix 1.1 Comparison of the Functions of Q Series C24/GX
