Why does the SR1B201BD module and ZELIO SOFT2 fail to communicate, "com error"?

This error is displayed because the software does not match the hardware used. In short, it is not possible to use Zelio Soft 1 programming software to program SR2** and SR3** relays, or Zelio Soft 2 to program SR1 relays.

The ZELIO range of programmable relays, part number SR 1**, are obsolete. Zelio Soft 1 software was used to program this range of relays. This software is also discontinued.

The ZELIO 2 range part numbers (SR2** (compact) and SR3** (modular)) replaced the old SR1 range and are still available. Zelio Soft 2 software is used to program this range of relays.
