Title: Displaying Thermocouple Data
Post by: Mikek on May 06, 2019, 01:02:34 PM

I am having issues displaying Thermocouple data . I can't seem to determine the proper V address to display.
I wish to display the values of channel 1+2 on a C-More HMI. I have tried the example from the 05/06 option modules user manual and IB-460.
The display needs to be 4 digit with out any fractional degrees displayed using Type K thermocouples.
Hardware:
D0-06AR
F0-04THM in slot 1
C-More EA9-10WCL

Software:
DirectSoft6
C-More 6.41

Any help would be appreciated.
Thank you in advance.

How do you have the Ibox or ladder setup?  That determines the V location.

Use one or the other method.  Don't use both to set up the card.

Your addresses start at V2000.  They use a double word in BCD format.  For your tag in C-more you need to pick BCD_Double_Word.  V2000 is your first channel and V2002 is the second channel.

Thanks for the reply.
I am just getting time to get back to this project. I am not seeing BCD double word as a data type option in C-More 6.41.
What am I missing?

Look for BCD Int 32

I have the display working correctly but am wondering if there is an easy way to have a BIAS/OFFSET? I need a way to"Calibrate" my thermocouple display.
