GC-5x replace



I would like to update GC-53LCx (53LMx / 55EMx / 56LCx).
Please tell me the successor model and update procedure when updating to the current product.



The GC-53 series is currently being replaced by the GC-A24-RS, but it is not a fully compatible product.
(GC-55 / GC-56 series is for GC-A26)

In addition, F / W Ver0.1.1.0 Build01 or later (produced after January 2021), GC-7x compatibility mode with improved compatibility with the old series is now available.

The project migration procedure when using this 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 the GC-70 series, it cannot be replaced.

3. Your connected device (PLC) is Please check if it is listed in “Vol_8_2_SCA2_SCREEN CREATOER 5” posted here.

4. A USB memory or SD card is required to download the project to the GC-A2x series.

5. 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.

6. In addition, display restrictions will occur due to changes in screen resolution.
