  1. Dear mrdegold, I referred your application to our R&D department. They found a bug in Visilogic that caused it to crash and already compiled a fix for this issue. This will be solved in the next release of Visilogic, which should be out soon. Thanks again for making Visilogic better.
  2. Hi HVG01, In the EX-RC1 webinar there is a comment regarding applications with more than 16MI's for I/O status. However, indeed there is no good practice of how to implement this in the EX-RC1. In the attached zipped folder you will find a sample Unistream project, EX-RC1 application and hardware configuration files. This example will be added to the standard Unilogic examples library.

  3. Hi Flex, I was just testing the Modbus IP R/W Mixed Data FB and I didn't encounter the issue you reported. Can you please post your application and mention the PLC's you are working with?
  4. Hi dtwbb, Thank you for this post. Currently, Visilogic does not have a feature for automatically landing on the most current trend data. I will make a suggestion to our R&D department to find a solution for your request.
  5. Hi CFBFP, In general, CANopen has a success bit for NMT, Emergency, TPDO and RPDO commands. However, SDO commands does not have this acknowledgment indication. If you cant use PDO commands in your application, you can try the following: Use SB242 (CANopen SDO in Progress) and SB243 (CANopen SDO transfer failed) to create logic that will resend a command in case it failed to send.
  6. Hi, To be able to log alarm history on the V350 you should add an SD card to the PLC. The text below is taken from Visilogic help. Please look into it for more details. Store Alarms History to SDIf a PLC contains an SD card, and the PLC application comprises Alarms, the PLC stores the first 8 Alarms in RAM, and then automatically transfers them to the Alarms folder on the SD card. You can view the Alarms file on PC via the SD Tools utilities. When the PLC writes this type of data to the SD card, it creates a file with the extension .ual in the Alarms folder. To cause the PLC to write the entire Alarms History to the SD Card, turn SB 352 ON in your application. An Alarm is added to the History buffer after it has: become Inactive and has no Pending actions: View, Acknowledge, Reset. The History display records the time the Alarm became active, the time it became inactive, and when Acknowledge and Reset were performed.
  7. Please ensure that your User Account Control settings are switched to Off. Also, you are welcome to post your application here and I will try to print is on my desk.
  8. Please re-download Visilogic from Unitronics website and follow these instructions: Backup you projects and delete all the files related to Unitronics installations. · Erase the “Unitronics VisiLogic_C” folder from- C:\Program Files\Unitronics · Erase the “Unitronics” folder from- C:\Program Files\Common Files. · Perform Windows update and restart the PC · Log-on as administrator · Save the setup file on your desktop and make sure that the installation file is not blocked (Right click on the file>Properties) If yes, just click on the unblock button · Install VisiLogic. After the installation is done, go to the properties of VisiLogic shortcut and under compatibility ticked verify the privilege Level “Run this program as an administrator”.
  9. Hi Apollas, The over/under range values are determined by each product separately. To find these values, you should look in the products specifications found in http://www.unitronics.com/support/technical-library
  10. Hi mrdegold, Which Visilogic version are you using? I tried printing in Visilogic V7.9.24 (the latest version) and it prints just fine. Try to upgrade if possible. If you are using the latest Visilogic version, please send a screenshot of the Print Menu so I can try to simulate.
  11. In normal installations this is not needed, and in most cases this process can be much shorter. However, it is better to take the longer path to a guaranteed success
  12. Hi, Please follow these instructions: Note that you need to install the software while the Windows UAC is OFF and after rebooting the PC. (VisiLogic V9.7.24 recommended) Turn OFF Windows UAC. 1. Delete the file Current_OPLC.udb from: C:\Program Files\Unitronics\Unitronics VisiLogic_C\Data\DB 2. Backup you projects and delete all the files related to Unitronics installations. 3. Erase the “Unitronics VisiLogic_C” folder from- C:\Program Files\Unitronics 4. Erase the “Unitronics” folder from- C:\Program Files\Common Files. 5. Perform Windows update and restart the PC 6. Log-on as administrator Save the setup file on your desktop and make sure that the installation file is not blocked (Right click on the file>Properties) If yes, just click on the unblock button: Install VisiLogic. If software opened properly, Go to the properties of VisiLogic shortcut and under compatibility ticked verify the Privilege Level “Run this program as an administrator”.
  13. As I explained, you can use up to four different devices over the Ethernet network. You can define different port for each device and communicate as you will... Please see the attached application. I sets up four sockets with consecutive ports 20255-20258 for TCP communication. All you need to do is define the IP address, port number and PLC name to open a connection. V130_4_Ethernet_Slaves.vlp
  14. Please see the attached application. I assembled it according to the "Descriptive Statistics" feature in Microsoft Excel. You may find it useful. Statistics_04_12.ulpr

  16. Unfortunately, with this configuration you will only be able to set one rotary encoder with index input. The other encoder will not be able to use its index input.
  17. Hi, With the Vision series, you can connect up to 4 devices via Ethernet, where each connection occupy one socket. Remote Operator opens the socket and keeps the link connected. If you want to create more than one connections to the same PLC (I would like to know what for exactly) you will need to create different connections from different sockets.
  18. Unistream works in the same way. You will find explanations regarding data tables in the Unilogic help file. If you still need assistance, I will be happy to help.
  19. Hi Cantcliff, That's quite clever. I didn't know that's how 2d arrays work. Anyway, it is much more simple to use data tables.
  20. Hi Sunit, I will answer your question in the order they were written: 1. You are correct. There is no "Z" (or index) input for the shaft encoder. However, you can connect the second HSI as a counter and program it as "counter reset". 2. I cannot find much sense in starting/stopping the counting mechanism (please please prove wrong). What you can do is to store the counter values into another operand, and work with the new operand. This way you can manipulate the second operand as you will, while the actual counter is not affected. 3. The solution above also works for this one. If you have further questions please post them here.
  21. Hi, First of all, two dimensional arrays are not available for Unitronics products. There are one dimensional array's available, usually referred to as Vectors. Second, in the M90/91 PLC's there is a small database for storing integer values, but it will not suit your needs because you need 5000 cells for your application. Finally, there is a very useful solution in the Vision series: the Data Tables feature enables you to store all values up to 192KB (depends on the model) locally, including easy store and retrieval of data. You can store any data type you like, export/import to Excel files and much more. For your convenience I attached the relevant topic from Visilogic (the Vision PLC's development environment) help file. data tables.pdf
  22. Hi Edwin, Unfortunately it is not possible to communicate with DMX 512 devices using our Vision controllers. The DMX 512 protocol communications baud rate is 250 Kbaud, which is not supported by Unitronics PLC's.
  23. For these requirements I would recommend the Vision V350-35-RA22. The short specs will be: 3.5" color touch screen (320X240 pixels). 8 DI 8 DO 2 AI 14 bit resolution, jumper selection between 0-10V/0-20mA/4-20mA 2 temperature measurement inputs (either PT100 or thermocouple) 2 AO 12 bit resolution, jumper selection between 0-10V/4-20mA Expansion port for adding I/O modules. Communication - one RS232/RS485 communication port. Optional communication modules available. For your convenience, please see the product page here, and a comparison table for the V350 here. I also referred your details to our branch in the US.
  24. Hello Brian, Thank you for your post. Unitronics offers various products that supports your configuration, with the main feature being an "all in one" solution of PLC+HMI combined. Please write a detailed description of your system, including the following: 1. Number of I/O's - digital and analog ( with analog IO's please mention desired resolution in bits). 2. Desired Screen size and technology - There are several screen sizes available, from 3.5" to 12.1" (in the "Vision" series). Most models consist of a color touchscreen, some of them have combined touchscreen and physical buttons and some are non touchscreen. Please define your requirements. 3. Environmental requirements - IP class, temperature ranges etc. 4. Please state the country you are operating from. We can connect you with our local distributor. Best regards
  25. Hi, Thank you for bringing up this issue. I checked your complaint and you are right! Some topics are missing from this version of Visilogic help. I have referred this tom our technical writers department and this will be taken care of soon. In the meantime, please see the information you requested in the attached file. Timers.pdf
