Trend don't show my tag

Hi, I have the eWON Flexy 201 and the PLC 1214C of Siemens connected by ISOTCP. I’m creating with ViewON a SCADA of electrical parameters.
I plot all my tags well in my SCADA but there are two that I can’t show. I observe that the two tags have a constant value, could this be the reason?

  1. The firts image show a voltage parametres in trend and works fine.
  2. In the second image you can see the bad trend. Show nothing and the value of tag is “50”.

Hi Miguel,

Can we set up a time for me to go through and take a look at this on teamviewer?
