Hi All, Came across something that may be an issue, unless I'm misapplying it. The Sort Array function seems to shift the array contents back and forth (ascending descending) each time its sorted. Meaning one time it moves it one way, the next time its sorted it moves it the other way. I've included a couple of screen shots to illustrate what I'm talking about as the program itself was too large to attach. The array is 10 bits in length, one of the interesting things is if you have less than 5 bits active, the sort function seems to sort everything one way. When you have 5 or 6 bits active it flops back and forth as mentioned above, when you have more than 6 bits active it sorts everything the opposite way. This is all regardless of what is selected for the ascending or descending option.

Thank you Cara I will give it a look.

Just make sure that your input and output scaling are the same and do a store from the input value to the output value. That is assuming you don't need to do anything else with it and it's a direct relationship between the two.

Hi All, Just picking brains. In the old Visologic software there was the Event Scan function which I found to be very useful and helpful in a lot of instances. I noticed that the Unistream doesn't have the same function (unless I just over looked it) any thoughts on how to get a similiar effect without 100 lines of code listing every bit? I've tried putting all the bits into an array, then converting bits to numeric and using math to watch the numeric to see how many bits are on... just seemed kinda clunky, funky and painful.

All loaded up, seems to be working well. Good job all and thanks again.

Thank you, I will give it a try.

Hi all, I didn't see this posted yet, might have been and I just missed it. I've come across a crash bug I thought I'd pass along. I tried to use the bug reporter but it wouldn't send (probably due to proxy settings and such on our systems here). Anyway. I've found that once you've been online, anytime you try to make a new timer the system crashes. Thankfully it's been recoverable each time, but the only way to break the cycle is to restart the computer. Scenario goes something like this: Go online look at some variables. Go offline. Drop a timer block on the ladder (I've used both TA and TON with similiar results) Use the variable creator and as soon as you go to save the timer you get a crash. I will attach the crash log. I am using the latest version of 1.14 Rev44 errors.txt

To follow up with this I have noticed a similiar issue with the Modbus RS485 Master. It will stop polling various points at various times. When the controller is first turned on, OR if you toggle the Modbus Active bit it will run through all the points, however after that some of the points drop out and no longer update (read or write). I have found by toggling the Modbus Active bit again you can get around this. I have noticed this in periodic and the on-demand version both. I alerted the Boston Office of this issue and they were looking into it. IN the mean time I've just set my program to toggle the Modbus active bit every couple of seconds and that has allowed me to limp through testing.

The information has been emailed, I apologize for the delay.

Thank you Emil, I will get this information together after lunch and send it out right away.

All the testing was done in our office at our desk away from any sources of noise. The incoming power was clean and stable.

Is anyone else having issues with the analog output tolerances on the vision controllers? We are currently using a v350 controller and running a 4-20mA output to a VFD which requires a fairly precise control level. Using the same program on three different controls we have found that the 4-20mA signal varies upwards of 1/2 mA - 1mA making precise control nearly impossible without testing a ton of units. We are well below the 500ohm limits, and we can see these variances with just a meter with or without load. The wiring when installled is 18AWG, shielded and runs approximately 2 feet. Any thoughts?

+4 I just makes me roar...

Ooo fantastic question... I find myself doing the same thing while fishing. Wondering which is the best specific place to start fishing for great white sharks. I like to find my specific spot by just randomly selected places. I tend to do the same while programming. Sometimes I just set a specific bit, sometimes I just drop some code... usually I get something to happen eventually, somtimes I do not. Sometimes I like to pretend I know what I'm doing, but most times I do not. In theory though I can just skip bits and make it work.
