i think we are going to hardwire another channel from the pressure-tranduscers output as "another channel5" and use it to divide/multiply on itself... also, we are looking into some labjack hardware, might throw one in the trailers and try it out!

i tried your initial reply, but somehow it shows up as a solid 50, dont know where that came from... anyway, i think it's going to be a little different since we dont use counters...everything i am scaling/using math on is a very small analog voltage and the ft/min aspect is calculated by a very "old school" pressure transducer that is gravity/water fed and is set on a 96min clock, but still 60min is the mutliplier, and how ever many minutes it takes from point a to point b is the divider.... i.e. - the pressure transducer shows the pipe went down 5ft in 4 mins.... 5*60 = 300 then 300/4 = 75ft/min i have it to where i can see the bristol pin movement in DF and it is scaled properly and reads the height of the moving "kelly" in feet... the tricky part is i don't need ft/min all the time, just when it gets to a certain point then starts to calculate...the certain point is the actual size of pipe measured, say 31.27 feet....the kelly will raise the pipe, then start to push in....so when it gets to 31.27, i need it to start ft/min...then it starts all over again with a new pipe size.... the goal i am looking for is just the ft/min aspect...the whole adding a certain pipe size then starting to calc is secondary...i'll try out that hertz over time measurement.... thanks again, your information is priceless.

dunno...i'll give it a whirl...

stumped again trying to read my channel, wait 60 seconds, read the value again and then add math to it... trying to find feet per minute... i have scaled my value to read feet, but getting it to read it, wait, then read again and divide/multiply has my brain crunching! it should be simple math, correct? forcing myself to read the whole users guide and im pretty sure it has something to do with the delay() or wait() statements.... any info would be awesome.... thanks!

is that a word? lol thanks again for everything

oh yea, i'm looking forward to the vertical graphs in DF 6.0! would be nice to see my graphs vertical, kinda like when they are printed... also, my boss noted that moving/rotating symbols would be a "cool" feature..

i guess i needed the whole item, record, and data for the code...like this - global string datain global data global record global item while (1) try datain = device.WITS.ReadUntil(10) if (strtodouble(datain) != NaN()) &= NaN()) record = strtodouble(left(datain,2)) item = strtodouble(mid(datain,2,2)) data = strtodouble(mid(datain,4,10)) endif catch() delay(0.1) endcatch endwhile thanks for that again! i'm not sure if i need .readuntil or just .read cause when i change readuntil to (1) or (100) i get an infinite loop or timeout error, but it does display until it errors out... i thought i wanted an infinite loop? this is the error - the code does work though, i am reading and displaying the data variable in a variable value component.. there is one problem though...the data coming in is this - it's reading all of those values and displaying them one at a time...all i want is the 3rd set, "7508.04", not the other values... do i need to make the code recognize the 0110 in the if statement somewhere?

i threw this in a new sequence and i'm getting an uncaught error in my sequence line 4 global string datain global data while (1) datain = device.serout.ReadUntil(10) if (strtodouble(datain) != NaN()) data = strtodouble(mid(datain,4,10)) endif catch() delay(0.1) endcatch endwhile can i do something like device.serout.readuntil (999999999999) and take the catch and delay off and add datain=datain+1? also a couple of OT questions - when is DF 6.0 coming? and will there be a charge to upgrade to it? also when i run this program on an old monitor with a really low res like 800x600, i can't "scroll" through my program...i tried to add a scroll bar, and for some reason, there is no "Vertical" tick box to check... thanks again for all your help...

edited! thanks again, i have to mess with the private string stuff, but the company man is happy! thanks*20-0.1

my math was off in trying to move the decimal... i needed write ("0140" format("%04.4f", ch1*20-0.01) thanks again for the help, really appreceiated...

i'll mess with it i dont need the item or record number...so i could just take those two out of the if statement, correct? or do i nan out the other items? something like this? put private data in the vari valu comp expression? - ignorance edit... thanks a ton... Brandon

how would i move the decimal left though, i can add 2, 4, 6 ect zeros on the right, but i want something like 0.00450 instead of 450... i have tried dividing/multiplying it out, but that's a no go though cause the ch1*2000-10 is the correct math for my channel 1's final value...if i divide 1000 or multi 1000, my value is incorrect... and yes, the chr(13) chr(10) are in the incoming serial data.. sorry if i double posted this and thanks

thanks! i was wondering which to look for, thought it was Format.String or toPrecision an example would be my output is being read as 400 when it should be 4.00... and my format is this device.serout.write("0140" + format("%04.1f", but i really believe it is the receiving pc..i think the scaling is wrong or something... i can monitor my device with the comm monitor and it is saying that it's Tx is 4.00, just the screen on the other pc is showing 400...i can't access the other pc's settings though..only with a call from tech support. the device i want to pull data from is transmitting a set of numbers in the same format as what i'm trying to send in... !! 01103850.00 && 01 = record number 10 = item number 3850.00 = channel value not sure on how to pull it from the set and display it. i was thinking it is device.serout.read Thanks! Brandon

Can DAQFactory use toPrecision() and/or toFixed() to move decimal places in a number being output say into a text document or to a receiving pc? i can move the decimal as far as i want to going to the right, but moving to the left is giving me troubles... also, how can i take a received signal over my serial connection and display it in a varial value component? would it be device.serialin.read? the same connection you helped me out with is in this post .. may have to create the protocol? Any info will be useful! Thanks! Brandon
