I am working on a Unitronics HMI/PLC that has not been fully programmed since new in 2014. Someone has touched it before me.
I cannot establish comms with UniLogic via USB or Enet. I have tried to do my homework.
Here are the facts:
I can boot to UniApps – after initialization and white screen I press top right touch screen
Trying to connect from Unilogic to PLC - USB and Ethernet fail to find any PLC
Panel IP is 192.168.1.5 in UniApps -> network
CPU is configured for 192.168.1.3
I can connect just fine with VNC client to 192.168.1.5 in UniApps -> network
192.168.1.3 CPU does not ping
Installed Unilogic as administrator
Device Mgr shows a com port number 6.
PLC force upgrade with DOK fails – The PLC upgrade files do not match or could not be found message….
Looking at the USB with UniApps -> memory ->SD browser shows all the files in a Unistream_Files folder.
I have a case into support but very unresponsive.
Thank you for any insight.
