  1. Common Data Table to Multiple V1210

    in Vision & Samba PLC + HMI Controllers & VisiLogic Software

    Posted

    Hi Mike,

    With Unican, you can send up to 16 MI's in every message. you can extract a data table row to a vector of MI's and then send it to each of the PLC's in the network (depends on the size of the data table - you may need more than one Send Unican function block to send the whole row.

    I made two applications to demonstrate a way to make this work. The first will send a whole data table row in a sequence that will send the whole table in the same subroutine, while the second will receive the data and distribute it to create a duplicate of the original data table. Please note that this is far from ideal and is only suitable for small data tables (if the table is too long you will get a watchdog error do to scan time length).

    A more sophisticated solution is to create a logic that will send only the values that were changed by the user. This will prevent high traffic over the bus.

    Also keep in mind that you need to send these messages to every unit separately.

    2. Download the installation file again from here: http://www.unitronics.com/downloads/support/visilogic/VisiLogicSetup_9_7_Build24.exe

    3. Before executing the installation file, make sure it is unblocked by right clicking the file icon-->select Properties-->press on the Unblock button.

    4. Run the installation file as administrator.

  7. Operand description is not shown in the ladder

    in Vision & Samba PLC + HMI Controllers & VisiLogic Software

    Posted

    When I put operand(which has a operand description) on the screen in the ladder, then I cannot see operand description. If it is the description short, it is shown, but only when it is MB operand. I have 9.3.1 version of Visilogic on Windows 7. I have tried advices (changing resolution, size of fonts etc..) which were mentioned in the other topic but they has not worked. College has the same version, same resolotion of the screen, same OS and it works correctly but He did not remember if He changed some settings. Could you help me?

    Hi,

    1. Please send screenshots of this issue.

    2. Please send the details of your system - CPU type, operating system, system memory etc.

    3. Anyway, we recommend updating your Visilogic version. The current version is 9.7.9, and has a lot of fixes in it.

  8. Jazz20 modbus doesn't work with even or odd parity

    in Jazz, M91 PLCs and U90Ladder

    Posted

    Hello,

    I tried to configure Modbus RTU network with few unitronics jazz plc, one of them was old JZ10 series controllers, and other was new JZ20 series controllers, the problem is that the new JZ20  doesn't transmit data when controller is configured to work in odd or even parity, then old series JZ10 controllers works fine with all parity types - none, odd and even. Is it a bug or I'm doing something wrong?

    Hi Martynas1

    I tested modbus communication for both JZ10 and JZ20 and both can successfully communicate with the Modbus protocol for different parity bit settings.

    Could you give some more information regarding this issue?

  9. Unable to connect with Samba Win7 32

    in Vision & Samba PLC + HMI Controllers & VisiLogic Software

    Posted

    Whenever I try to connect with Samba (SM35-J-R20) via VisiLogic (9.7.9 Build2 OS Windows7 32 bit) i receive error 206 (Communication driver error), I/m unable even to  get com parameters by connection->Communication &OS-->PLC Status

    I have tried Build in port as well as USB-rs232 converter, checked port nr, baud, fifo etc...

    Cable is fine - works perfectly on laptop with win XP.

    Following instructions concerning UAC did nothing, as well as running as administrator.

    Downloading new install file also didn't helped...

    Once in a while whole application crashes (Some infinite comm loop?).

    Is there any other options i could try?

     

    Hi,

    Several questions:

    1. Can you connect to the Samba PLC from the laptop running Windows XP?

    2. Can you connect to other PLC's from Visilogic on Windows 7?

    3. What type of USB to RS232 converter are you using?

    Hello all, I'm new to these components and the forum and looking for advise. Any help would be greatly appreciated.

     

    First off I received a unit that was supposed to be pre-programmed, but it was not so I finally got programmed. My problem is that it is supposed to fire the relays every 28 seconds and it does not. I can access the menu and fire the relays "manually" but I can't figure out why program is not working. Any advise/troubleshooting tips for a newbie?? I'm thinking that the initialization string maybe wrong...just not sure what I'm looking at to tell.

     

    Thank you in advance for any and all help.

     

    Hi,

     

    Please send the application to support@unitronics.com and describe exactly what you want to achieve.

  23. Simple Communication RS232

    in We're Listening...

    Hi Alberto,

    First of all, there are no attachments in your post.

    Second, I would check the status of the USB to Serial adapter by opening the device manager in windows. Simply type "device manager" in the search pane inn the Windows start menu. click on the device manager icon and from the window that will pop up, select "Ports (COM & LPT)". You should see a device named "Prolific USB to Serial Comm Port" and a port number in the parenthesis.

    After discovering the com port that is attached to your USB to Serial adapter, go to Visilogic, select the "Connection" menu and select "Communication & OS". From the window select the port number that corresponds to the one that appeared in the device manager.

    That should solve the connection problems. If you still having communication issues (or any other issues) you are more than welcome to contact us at support@unitronics.com.

  24. Alarms Display V570

    in We're Listening...

    Hi again Eyal Koren.

    Thank you for all support. Now i finely understand how the Alarm Displays works.

    I send you my test projekt so you can se the problem I have.

    I am working with diesel Power plants,and we make our own softwear.

    Look at the ladder code, this is a very common way to create alarms with Reset.

    It is for the ladder code(not the alarm screen)to deside if the alarm is reset able

    or not. If the alarm (MB940) is active, the alarm is not reset able.

    Is it possible to get an option Reset MB with the next update, so that the alarm screens

    reset button works even if the alarm signal is active.

    attachicon.gifmicke-alarms.vlp

    Iv'e looked over your application. You were using a simple self-holding mechanism to keep MB31 energized. The thing is this: In an actual system you anyway won't be able to reset the alarm until you will reset MB940, because it will keep the self-holding mechanism energized all the time.
