Notes

1. If the project for GC-50 is not on your computer, you need to perform operations such as uploading from the HMI and restoring the uploaded project.
2. If the project uploaded from the HMI does not have editable screen data, or if you are using a connected device (PLC) that is not compatible with SCA2, it cannot be replaced.
3. The GC-50 series has a DSUB 9-pin (female) serial communication port connector, while the GC-A2 series has a DSUB 15-pin (male).
* If you want to use the cable used for the GC-50 as it is, create a connector conversion cable.
* For the conversion cable, see here.
4. In addition, display restrictions will occur due to changes in screen resolution.
