  1. Hello! Is it possible to communicate over Ethernet with a Vision 350 over the 3G mobile network? I would like to use the remote operator to remotely connect me with this plc. Had planned to connect the PLC to a Dovado 3GN router and a 3G modem Huawei E1820. Is it possible to use dynamic DNS for this or do I have a static IP address?
  2. Hi! I'm sorry I was so clumsy. Thanks for all your help. //Hanna
  3. Hi! In the module, it is written only IO-PT4. This module, I think we used many years ago with PT1000 sensors? The SN numbers are:91D00535
