InView Panel Displays In-accurate temp.

Guys,

Kindly help me sort this thing out. We are monitoring our winding temperature thru 6-points with one RTD each. 5 points are reading an average of 78 deg C while one point reads only about 57 deg C.

I did verify the reading by hooking my laptop and get on-line reading.Surprisingly, all 6-points are reading almost the same but on the inview, that one point previously mentioned has a difference of at least 15 deg C.

Where you guys think the problem is?

Cheers!

You did not mention the plc but I have to "assume" that something has altered how the program is doing the scaling OR the HMI is altering the numbers after reading them.

Hi rsdoran,

the reading on the PLC is ok as far as the figure im getting on the laptop is concerned.

any other thing to check?

regards,

gado
