Hello, i'm using V700 and i have a strange bug with screen. So, basically, i have some Variable: Numeric parameters on the screen which i can set with keypad entry, all works fine with it and also I have some buttons on the screen like "Copy" or "Load" or "Save" with confirmation of action, after that i get pop-out message and while that message is shown i turn on SB111 (disable virtual keypad). And sometimes after that action i get pop-out virtual keyboard with one of my parameter for no reason, even when virtual keypad disabled. Sometimes virtual keyboard pop-out even while SB111 is still TRUE, which scares me even more. I was trying to swap this "buggy" parameter with another, but now virtual keyboard with another parameter pops-out for no reason. Sometimes it happens like 3 time in a row after some other action on the screen (pressing "Load"), sometimes it might happen even with external buttons (Start, Stop, Reverse), which i do not use to disable virtual keypad and sometimes i might press buttons like 50 times and get nothing. I was thinking about protective film that adheres too tightly to the screen in a particular place, but not sure about it. Did someone encountered this bug with V700 or maybe another unitronics model? I will try to download video with this bug later today, can't do this now. Thx and sorry for bad english Edit: actually, i have some external button which sets SB111 Edit 2: adding video: https://drive.google.com/file/d/1PLHBbHfPIqx8DdyujtVMKi35LvEBSyt2/view?usp=sharing

Ausman, ty for answer, bought 5mm and it fit perfectly! -
HSC and SCADA issue
Pavel M replied to vasovas's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Hello vasovas, you can compare SI 37 with some MI on every start wih SB2 If it differs - store your HSC value, reset it and rewrite MI with SI 37 If it same - do nothing Must work fine if you don't get downtime month, but as you mentioned, you might also include SI 38 in condition -
Hello I want to add some visualisation to my project, so i have some questions: is that possible to make Variable: Bargraph to change its fill colour when it reaches some value? Or, is that possible with Variable: Meter make ranges (From-To) not as constant values, but as variables? The problem is: i want to show productivity as a Meter and Temperature as a Bargraph, but my productivity is not a constant value, every time i set some productivity as a parameter i want to cut some from my possible maximum and from my possible minimum. Same with temperature, i have temperature as a parameter and i have some working range, so i want just to show, for example, my current temperature and working range +- 5 degrees and if my temperature out of range or close to be out of range - show it with different colour. Or do i need to use some extra pictures like lights to properly show it? Thanks and sorry for bad English

Reset HSC
Pavel M replied to CobryWZL's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Depends on what you read with a high-speed counter. If this is an encoder that rotates with the engine, in your program you can stop the engine at the same time and write 0 to the encoder variable, but the inertia remains and the variable of the high-speed counter changes by a certain number of units even if you set EndSub right after this event So, probably, if you need 0 in your counter, you need to wait some time after you stop some output, which changes your counter and only after this task store 0 in hsc variable -
Hello, so i tried to organize PWM on my output and put it on my digital input Duty cycle is always constant - 500 (my meander) So, with cycle time 8, i get +25 in my memory integer (50Hz) With cycle time 4 i get +50 in my memory integer (100Hz) When i change cycle time to 3 or less, i start to get errors (+50 all the time) With cycle time 1 I get nothing at all So, i guess, i'll need to buy expansion module with high-speed inputs

Hello, i need to count pulses, when i get the amount of pulses i need - i take some action, reset this counter value and probably, change my target counter, but the frequency with which these pulses are given is different, i mean, 400 pulses/s is maximum and it is not always 400, most part of time this frequency would be less, so i guess, i can handle that and even if i get some error, it won't be critical. Thank you everyone for answers!

Thank you for the answer In manual for E4XB i've read, that responce time for I0-I3 is 10mSec, but for I4-I17 is 2mSec Unfortunately, my inputs I0-I3 are busy with shaft encoders, i have some free inputs, so i decided not to add expansion module only for high-speed input and try to make it the way i described before

Hello I'm using V700 with 18E3/4XB and trying to make impulse counter without using high-speed input The problem is, input frequency is about 400Hz. Input pulse is always meander So, the question is: is that possible to make it with 1.25ms interrupt + immediate read physical input? Just put positive transition contact with increment of some integer I was thinking, that with 400hz/s i have circle time 2.5ms, with duty cycle 50% i react on every impulse. So, frequency 400Hz is my maximum without errors Is that possible to create and organize or am i missing something?

Active Screen

There are SI251 and SI252 which shows previous HMI display number and current HMI display number
