My LOGO 0BA1 device is not connecting to my PC. The program I'm using is version 8.2.

Kind regards, Moderator_Lan

0BA1 is not a complete designation.
A 0BA1 would be a LOGO! that is over "25 years" old.

You probably mean a LOGO! 8.3.
The order number would be, for example, 6ED1052-1MD08-0BA1. The "08" in this position is important.

For this, you need at least LSC V8.3.x.
It would be better to upgrade directly to the current LSC V8.4.1.

You can download the free upgrade from here:

Firmware update for LOGO! 8.4 basic devices and service pack 1 for LOGO! Soft Comfort V8.4
