Samba virtual keyboard buttons stay pressed

Recommended Posts


with the latest batch of Samba SM35-J-T20 PLC's I've programmed, I have noticed that the buttons in the virtual keyboard stay pressed when you touch them once. I must touch them again to make the button appear unpressed.

Is this a change in the firmware? It seems to work anyway. Just curious what is causing this.

Buttons stay pressed with this PLC
Firmware: 4.4 (28) Oct 16 2017

Buttons works normally with this PLC

It's the same phenomenon with a SM35-J-TA22 straight out of the box when I enter Info mode.

After updating the PLC the issue was resolved.
