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.

1 There is a limitation in the production date of the Q series C24 that contains functions that are usable.

For version verification, see section 2.6.

2 The data reception using format-0 refers to the method of receiving data by user frame, which was supported in the Q series C24 of function version A.

3 The Q series C24 of function version A is capable of setting one pair of transparent code and additional code per interface for both transmission and reception.

4 This function can be used when connecting with GX Developer.

5 This function is available in GX Developer Version 6 or later.

6 GX Developer can only be connected to the CH1 side in case of the Q series C24 of function version A.

It is not possible to connect both GX Developer and the GOT to the two interfaces at the same time.

Appendix 1.2 Precautions when Updating the Module from Function Version A to B

This section explains how to utilize programs created for the Q series C24 of function version A for the Q series C24 of function version B and how to incorporate function version B into the existing system.

(1) Program utilization

Programs created for the Q series C24 of function version A can be used as they are for the Q series C24 of function version B.

(2) Incorporation into the existing system

The wiring used for function version A can be used as is for the Q series C24 of function version B.
