Hi all,

i am a novice when it comes to SCADA and i only had success in using CIMON SCADA from Korea. Our company uses Unitronics plc's and i am testing Iconics Genesis32 SCADA with Unitronics' UniOPC Server. I am having problems making tags for the UniOPC. Has anyone here used Gen32 with Unitronics UniOPC Server? I am really having trouble with this.

Thank You,

Hi Paul,

I have used Genesis32 with Unitronics PLC's before. The Unitronics OPC server does not support the tag browser interface so you have to enter the tags manually. If you name your server that is connected to the PLC "unit1" then the tag to access Memory Integer 127 would be "UNITRONICS.OPC_Server.1\unit1.MI127". (without the quotes) In many cases in the PLC we use an MI for holding a data value, eg, a temperature of 62.17 is stored as 6217 and then has to be scaled by a factor of 100 to display it on the PLC or an HMI. To scale it with Genesis32 by dividing by 100 you enter the tag like this.
x={{UNITRONICS.OPC_Server.1\unit1.MI127}} / 100
Hope that helps!
