GC-7x replace
Question
I would like to update the GC-70 series HMI.
Please tell me the successor model and update procedure when updating to the current product.
Answer
The GC-70 series is currently being replaced by the GC-A2 series, but it is not a fully compatible product.
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.
Notes
1. A USB memory is required to download the project to the GC-A2 series.
2. Please check whether the connected device you are using is listed in “Vol_8_2_SCA2_SCREEN CREATOER 5 Edition”.
3.If you are using K-BASIC to control the screen, the switching speed may be slow.
* Please use the parts of Screen Creator Advance2 instead.
4. If you are making a push button SW using texture parts, the response speed of button operations may be slow.
* Please delete the texture before use.
5.Other display restrictions may occur due to changes in screen resolution.
