lfreeman4511 posted a topic in Vision & Samba PLC + HMI Controllers & VisiLogic SoftwareHas anyone created a stopwatch in Visilogic? Here's what I am trying to achieve: Machine jams, Stopwatch starts, Operator clears jam, Stopwatch time is recorded in bit, Stopwatch Resets Right now I am using Accumulating Timers to simulate, then calculate this during an entire 12 hour shift, but would like to have something appear on the display that resembles a stopwatch with the jam message.
kilca posted a topic in Vision & Samba PLC + HMI Controllers & VisiLogic SoftwareHello, First I would like to apologize for my bad english. I'm working on program which is completely controlling system of solar panels, as a diploma work. I've got few problems but this one makes me sad. I can't figure out, how to correctly setup real time clock. I've tried examples in visilogic directory, searched the whole help at the program but after 2 days, still can't make it work. The best way possible for me would be having DW with real time information about time, such as DD.MM.YY and HH.MM.SS ... If it's even possible, because, I'm having many operations which will need to write time when it happened and only one DW with time would save me much space in ladder. But, I will be satisfied with any other working option. I've found SI30-36 but they are read only, so I can't use them to write there down todays time. Since I'm still beginner with ladder programming, can someone please give me an advice? I'm really desperate. I will give more information, if needed. Just leave me here a message. Thanks in advance for help. Best regards Martin P. EDIT: I may find a way but I can't figure out how to increase DW by 1. It increasing something but more then it should, like 50 per sec. Is there way to do it? Thanks again!
Is it possible in Visilogic to make a counter based on the clock speed? An other possibility is using the standard timers, but we need the possibility tot start a process, and keep tracking (and showing) the time that the process has been running (without time limitation).
galluccinator posted a topic in Vision & Samba PLC + HMI Controllers & VisiLogic SoftwareHello, I am designing a rig for a very fast, time sensitive experiment. The end result is to have a plot with pressure change versus time, so it needs to measure on the order of miliiseconds. I have a Vision 570, and the newest software. I already am able to take ~10 ms increment data and store it into a data table. Is there any way to record the RTC in milliseconds and store that in the data table as well? The system Integers don't seem to have that precision. Note: I do NOT want the scan time resolution, I want the actual time the data point is being taken, so I will need either a timer or real time clock that has this precision. Thanks in advance!!
