  1. Thank you Isakovic, for your help too.

    Yes, it can work as NTP server. Can I test this function with my PC? Because I have configured my Win10 to work as NTP server. So, theoretically speaking, if I enter my PC IP adress in RFC block, after I upload software to PLC, will it sync time from my PC?

    Please, see picture attached.

    EDIT: Sorry, on CMD screen, I have marked wrong line, but below can be seen that server is enabled (set to 1).

    Cheers,

    Petar

  2. Hi,

    I'm using V130 to control school shedules and some building automations. They recently added "Master clock", device that sync it own internal time via GPS. It has several communication protocols, but the only one that is maybe usable for me is SNMP.

    I must admit, this is the first time I met with this kind of protocol, so I need some tips from you guys.

    Namely, idea was that V130 internal clock is syncronized with the Master clock, so I thought that I can use SNMP. My question is, does that can be done?

    I mean, it looks theoreticaly possible to me - to store MI that I receive from Master clock, and store it to SI (35,36,37)?

    If someone is willing to take a look, model of Master clock is attached in PDF. It is Rack version.

    Thank you in advance for any help.

    Sure you did. If your scaling is 0-5bar and you put 0-50 in your linearization block, then your resulting value after linearization will be in increments of 0.1bar.

    I'm sorry I didn't write earlier. Thank you very much for this tip, I got exactly what I needed.

    Once again, thank you.

  4. Thank you for the reply. I'm not currently near office to try that, but...

    If I understand you well - when I multiply my scaling x10, in my case that will be MI11, istead of (for example) reading of 5bar, I will be getting 50bar, so when I put decimal place, it will be 5,0.

    In that case I didn't get anything...

  5. Hi,

    I have some analog inputs (temperature and pressure measurements) and I wanted to show them in decimals.

    Picture of one of scalling is attached. So, my MI11 is displaying as whole number, but I need it more precise (one decimal point).

    In my situation, when I enter that pump power off after pressure is higher than 5bar, it shuts off after 4.5bar and that makes me problems...

    I tried to change how it shows in display variable format, but I can't do anything as my result of scalling is whole number, right?

  6. Hi,

    back to this problem. I have tried new clean install of Visilogic (as Admin), but nothing happened. Then tried Samba on other computer where I know for sure that Visilogic doesn't make problems, and I got same memory problem when I try to run online mode with this software uploaded on PLC.

    Though i didn't think, the problem was definitely related with PLC memory...

    So, your suggestion is to contact Support?

    Thanks again.

  7. PC memory is not problem, when running Visilogic it's used under 20% of 24gb.

    I didn't used installation metod "as admin", but I must admit, I have never use that metod for Visilogic before, and also never experienced that problem like now.

    For start, I will now unistall and install it again with Admin privileges.

    After that I will try empty Samba, and I will inform you about result.

    Thank you very much for tips!

    Cheers

  8. Hi,

    I have problems with Visilogic software,  when I'm in online mode. I'm unable to do online test, because every 1-2 minutes online is interrupted with message attached in this post.

    After confirming with OK, Visilogic shuts down itself. This makes big problems to me because I'm unable to test my software, as it has much timers which I must to monitor.

    Visilogic version: 9.8.90 Build0 (also happened with previous version)

    PLC - Samba SM35-J-R22

    NOTE: I don't know if this can make problems, but PLC is on 100% memory usage (no free space). I have tested for now on 15+ pcs of this Samba, and with every PLC I have same problem.

    I didn't noticed earlier this bug, when PLC memory wasn't so full.

    I have tried to uninstall/install Visilogic but with no luck.

    Any help is welcome.

  9. Thank you for your response.

    Unfortunately, I still didn't managed to send list of MI. I have attached printscreen.

    Length of MI is 20.

    When I send protocol to printer, I'm not getting anything.

    As I said in first post, printer works fine, and I can print everything else except list of MI...

    Thank you,

    Petar

    EDIT: While waiting to this post be approved, I have managed to solve the problem using Stream insted of List Of text.

  10. Hi,

    I have sucessufully connected thermal printer (via RS232) to Samba SM35 and everything works perfect, BUT...

    I didn' find way how to print List Of Text. For example, like in attached picture, I have some MI lists, defined under "Link" and their length is 20.

    But when I try to print that, I'm getting nothing but blank paper.

    Numeric and binary text works fine, so I suppose that I'm missing something with List of Text.

    Any tips, hints will be great.

    Cheers,

  11. Hello,

    I'm using multiply formula and storing result into MF. I'm displaying results on display, and my problem is that result have 6 decimals, but I only need 1 or 2...

    For better understanding, for example, I want to number 6.543210 display as 6.54 or 6.5.

    By default, display settings when using MF are greyed out, and can't change decimal points (picture attached)...

    Any suggestions, tips?

    Thanks,

    Petar

  12. Hi,
    I wanted to protect some info on my HMI using Password Box, but I can't figure out how do I choose password?

    I tried to use Compare Strings in ladder, but I can not compare tag that I used for Password Box, because second element in Compare Strings block can not be constant value (in my case correct password, which must be constant number). Can someone give me some tips about this?

    Thank you in advance.
    Cheers!

  13. Let me try to explain my whole idea best as I can...

    Rung 6 - I'm writing in array values that I'm getting from analog input (value is previously linearized) and that is TalkKgIzmereno. In this case I'm getting value of 12.

    That value is stored in Array Talk [Array Talk_0] when I press StartTalk button. My mistake is that I didn's show on picture, that I have also button for Remove From Array block, so I can erase data from Array Talk and store again new value if I need in same array.

    Rung 7- I'm trying to read value from that same Array, Array Talk [Array Talk_0] and store it in proba (so I can use that value for further compares). In this case it is previously saved value 12.

    As I written in first post, Storing (and Removing) values from array works as expected, but I can't Load value.

    I hope that this explanation is little bit understoodable than previous...

    Again, thanks for your time and help

  14. Hi everyone!

    I need advice what is the right way to load from an array?

    Below is picture of my ladder, where is also shown previously stored data in the same array that I want to load from.

    Rung 6 - data is saved from C  (TalkKgIzmereno)  into B ( Array Talk[Array Talk_0] )

    Rung 7 - I want to load result from B ( Array Talk[Array Talk_0] ) into C (proba)

    Storing in Array woks perfect, but didn't have success to load...

    Thanks in advance!
