GC-50 series update to SCA2



I would like to update the GC-50 series.

At that time, I would like to use the new drawing software: SCREEN CREATOR ADVANCE 2 (hereinafter referred to as SCA2).

Please tell me the procedure for migrating to the successor model and new tool when updating to the current product.



The GC-50 series is currently being replaced by the GC-A2 series, but it is not a fully compatible product.

The project migration procedure when using the new tool (SCA2) is as follows.

For details, please read the explanation below from the model number comparison table.


1. If the project for GC-50 is not on your computer, you need to perform operations such as uploading from the display and restoring the uploaded project.

2. If the project uploaded from the display 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.

5. For details, posted here > Please see “Vol_8_SCA2_Model number transfer_V02”.
