I have a application I am making that I need to log 8 diffrent temperatures each is a diffrent chamber. I need to also be able to list the part number of the part in the chamber and there is 15 diffrent part numbers for each chamber. I talked to tech support and tried what they suggested but I can not have more than 16 trends on the screen. What I tried is setting up a recipe which works fine it turns on the visibality on the trend I set up diffrent trends for each part number but like I say it will not work to many trends. Any one have any ideas?

Thanks for any help

Clarification Please. As I read your first two sentences, I see the need for 8 temp sensors trends, one for each of the 8 chambers. Then it gets fuzzy. You say you "need to also be able to list the part number of the part in the chamber ".

Is there only 1 part number in each chamber and 15 different possible part numbers that it could be, or could each chamber hold several part numbers at once?

Also are you trying to see the part number on the cmore chart, or in the data log file?

If only 1 part in each chamber at a time and storing the data log file, you can use the cmore to numeric enter the part number in each chamber and store those part numbers in your plc in individual vmem locations. When you set up your trend screen, pen 1 is chamber 1 temp, pen 2 is chamber 1 part number mapped to proper vmem with the pen and line not chosen. This will store both on the log chart and 8 chambers and 8 pens is your 16 total.

Please clarify your storage needs and desires if you need more help,

Bob,

Thanks for replying. I there is only one part per chamber at one time with a posibillty of 15 diffrent ones the part number containes numbers and letters. I only need to see the part number on the log. I have this working using only numbers to the v mem location then using a excel sheet to cross the right part number. I would like to have the exact part number in the log file but not sure if this is possible. Thanks for all the help.

Perfect. As I mentioned above, you'll need to put a numeric entry object on your screen, or some other entry option, to store the part number associated with chamber 1 into an open vmemory location in your PLC. Do this for each chamber.

Set up pen 1 of your trend to log chamber 1 temp and put in the line details choices.

Set up pen 2 of your trend to log chamber 1 part number(tagged to proper vmem location) and don't choose any line and color choices. This number will then show up on your log file only.

Your log file will look like this...

Time-------Date----------temp1-part1-temp2-part2-temp3-part3-etc...

03:11:33 10-01-2009 1255 123456 1409 654321 0957 555555

03:13:33 10-01-2009 1276 123456 1404 654321 0957 555555

Is that what you 're after?

Ouch, that might be tough. I just tried an expirement, and can use the "Text Entry " to store an ASCII string to internal and probably DEV1 PLC.

However, when I tried to create a "PEN " in a line trend graph, it didn't allow that type of memory tag to be entered.

Hopefully someone else has experience with this, as I have only worked with numbers on this type of stuff.

Good Luck,
