  1. 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 S
  2. Ausman, ty for answer, bought 5mm and it fit perfectly!
  3. Hello, i'm using 18-E4XB with standart (straight) terminal blocks and i want to switch them to corner terminal blocks Is there any documentation where i can find correct contact pitch so i don't mess up when i buy corner terminal blocks?
  4. 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
  5. 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 temperatur
  6. 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
  7. Hello, did not find similar topics on this forum Is that possible to connect snap I/O module with vision not by direct installing, but with some random 34-pin cable?
  8. 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
  9. 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!
  10. Sorry, did not see i double-posted, just had issues with posting answer, refreshed page few times, did not see my reply and decided to post it, but forum decided to post it twice Thanks
  11. 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
  12. 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 somethi
  13. There are SI251 and SI252 which shows previous HMI display number and current HMI display number
  14. Hello and thank you everyone for answers That is true, im using wrong usb to serial adapter, i saw someone used CH-340 so i decided to buy some random cable with the same driver, but mine was without power on pins 1 and 6. I found old pc with com port and communication works fine Ok, we learned, thank you again Pavel M
  15. Hello, i'm trying to communicate old JZ10-11-T40 with my PC, but can't do it properly. What did i do: 1. Installed driver USB-to-serial 2. Installed USB driver from U90 ladder 3. Turned ON PLC 4. Got connection from PLC to PC through this chain MJ-20PRG > MJ20-CB200 > MJ10-22-CS10 > USB-to-serial adapter When i'm trying to get PLC version - i get nothing This error appears all the time, but the interesting thing is next: When i try to get version - it is trying to synchronize COM ports and then this error above appears When i pres
  16. Hello, there were a lot of topics here on this forum about PID regulation, but i still got some questions about PID: - i've connected PT100, which i can regulate manually, when i run autotune i have some parameters been written in vector in like 1 second, but then they all overwritten by 0, i do not get "autotune done" bit into 1, my autotune does not turn off and it does nothing when i try to change PV and i do not get any P, I and D parameters; so, do i need like fully completed loop with my actual heater and output CV (PWM) which will control my heater? or there any other way i can tes
  17. Hello everyone I have a question about temperature of plc. I am using V700 and in tech spec i see the working temperature 0 - 50 degrees of celsium and i can check it by turning on SB14 and the value will be shown in SI14. So here is the question - does it have build-in protection from overheat or undercooling or do i have to organize it by myself? Did not find the answer here, so decided to start new topic. I don't think that i need it for my current system, but still getting some extra information about it might be viable. Sorry for bad english, it is not my native language
  18. Thanks for reply. I was not involved in choosing platform, my directors were, but V700 seems fine to handle our task. Probably in future they'll make a decision to change to UniStream. I haven't download UniLogic yet, because i'm not familiar with ladder logic at all and haven't got almost any experience in it, but i'll probably download it later and check this program product also just for myself.

  19. Hello everyone, i found some similar topics about passwords but they did not help me, so i decided to start this one. What i'm trying to do is make multiple access levels. So i need 17 passwords, first i was trying to make legal entries as vector of DW operands, but it seems that it works only for one operand which sits in DW20. Here is screenshot. (Yes, i linked MB13 to legal entry, not on this screenshot, but in project) After that i was trying to link it to data table, but it did not work for me In data tables there are no IDs, just passwords, so there i
