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.
