jazz firmware update

Recommended Posts

Hello,

 

Is there a possibility to update jazz firmware via modbus?

By that i mean to read data via modbus and then execute the update.

 

Or is the only possibility to manualy update with u90ladder?

 

Thanks, Pawks

Hi ,

 

Updating Jazz firmware can be done only via Unitronics tools such as U90Ladder.

The update is done using special Unitronics protocol and cannot be done via MODBUS.

MODBUS is a protocol for exchaning registers and coils and not updating OS or application.
