  1. Hi Joe, Thank you for the answer, Indeed i am using Modbus TCP communication between the SCADA and the PLC What do you mean in the second question? I didn't understand.
  2. Hello, I have PLC V280-18-B20 and SCADA GE Cimplicity I have a SW that monitores network assets and traffic, and it noticed (first time) that there was an attempt to communicate from the PLC to SCADA on port 56780 This is the first time that PLC initiates communication with the SCADA And this is the first time I can see unitronics using port 56780. The firewall dropped the session, but it looks suspicious to me, Did anyone expirienced something like this?
  3. Thank you for the answer! I would like to perform Upload to the project with the current tag values. The most important values for me is the parameters (such as alarm parameters, proccess parameters, setpoints). Those values do not change that frueqent thus i don't really need to stop the program. Cna please specify the commands for the upload?
  4. Hi, I would like to upload the values of the tags to the existing project and in some cases to upload the project from the PLC, Is it possible?
  5. Hello I want to develop a module that performs auto backup for Unitronics PLCs. Is there any conventional way to perform auto backup?
