Trend causes t/c input to stop working??

[PCSControls]

I have a V570 with a V200-18-E3XB snap in card. I have a simple numeric on the screen that displays the temperature of the t/c connected to ain0 and this works OK. When I add a TREND graphic and download to the V570 the numeric displays "0.1" and the trend does not display proper data either, If I delete the trend the numeric updates properly with the expected temperature values.

Any Ideas ?

Hi,

Please check if you use in a Ladder the same MI for Trend and TC.

Check power connection to snap in card.

There is no idea without knowing what exactly you are doing.
