You stated I1 is high? Are you seeing this is the software? If I1 is high, then you are resetting your counter. This could explain what you are seeing. Do you know if the V120 was set to pnp inputs or npn? Also, what are the digital inputs set to on the V130 unit?

Hello, VisiLogic did not contain structs; this is a feature within UniLogic. Could you please explain further by what you mean for VisiLogic? Are you able to assign vectors to Modbus read and write commands now?

Hello, The Modbus commands are still there, they are just configured for you. When you assign a tag to the operation, you have the option to set an array length. This will either read to that array, or write form that array, depending on what you are trying to do. The same is also true when you create a Modbus slave. When the tag is created/assigned, you assign the array length as well. Hope this helps!

To be more clear, here is a photo of what I mean by "staggering". (thanks @Flex727)

Hello, VNC is purely for panel connections. It is not for programming purposes. If you wish to remotely download or go online with UniStream products, the unit must be on a network with internet connection. The modem the unit is hooked up to must have port forwarding set up for connection to the UniStream. Then, in VisiLogic, when connecting to the unit, you must type the IP address of the modem, and the port the unit is connected to. Then you will have connection to the unit for access like downloading and going online. Please note, the modem may need a static WAN IP address to connect to for this scenario. Hope this helps!

Hello, In VisiLogic, it is possible to extend the vertical length (or height) of the net. However, it is at a fixed width, and in order to make long rungs, you must stagger (or "snake") the rungs. Hope this helps.

Hello Olaf, UniOPC Server is in compliance with the OPC DA v2.x specifications. Hope this helps!

Hello Rene, Please ensure you are using the most up to date OS (Firmware Version 1.12.7, associated with VisiLogic 1.20 Rev 20). We have not experienced any issues with Modbus over RS485 with this OS version. Please let us know if this helps, or if this does not resolve your issue.

Hello, If you are comfortable with ladder logic programming already, I would start by watching these three videos: 1. Data Tables: http://unitronics.com/support/webinars/data-tables-part-1 2. SD Card: http://unitronics.com/support/webinars/sd-card 3. Communications: http://unitronics.com/support/webinars/communication-and-os Please note we have plenty more tutorials to help you with you project at www.unitronics.com/webinars Also, we have project example applications already built, which is included with VisiLogic. Navigate to the "Help" tab, then select the "Examples..." option. In the pop-up window, enter the "Version 900" folder, then the "Project Examples". Here you will find all of the folders for communications, SD card examples, Data table examples, and much more. In order to help further with your "data exchange" portion, we would have to know more about what you trying to communicate with, what you are exchanging data with or logging to. Let us know if this helps!

Hello Oskar, Have you watched our webinars? These will help you to get started with our software and help you understand where things are to complete your project. I recommend watching the following videos to start you off: http://unitronics.com/support/webinars -Lights and Button Programming -Timers, HMI jumps, and more programming -Analog Programming I believe these videos will really help you along with your project. The HW configurator contains all of our products (PLC + HMIs, Expansion units, etc.) so there will be a lot that may not look familiar to you. Basically, you should choose the unit you have (SM43) then it will prompt you for the exact type it is, which will determine you I/O (with you have the T20 model versus the R20 model). Overall, I suggest watching the tutorials above first, then start mapping out your I/O and working on the logic. The videos will help you understand how the HMIs are made, how to work with analog and digital I/O. Furthermore, we have example applications to help you along with your project in VisiLogic. Please navigate to the help tab in VisiLogic, and choose the "Examples..." option, which will bring up a pop-up window. Enter the "Version 900" folder, and then you can choose between project examples or functional examples. It is fairly easy to convert projects made for other controllers to your controller type too. Please let us know if this helps!

Hello, Yes, this is entirely possible with use of the data tables and SD card or USB drive. Just save the values you want to back up as a Data Table Indexed, then store the DTI to a file. When you wish to retrieve the value, load the DTI from the file. Let us know if this helps!

Hello Bob, There is no file attached. Please upload file here or send to support@unitronics.com .

Hello, You should be able to see the MI register change when you go online with the controller as the signal from the sensor changes after you have linked the MI to the input register. If you want to link this input value to an element on screen, go to the display editor, select the amount of digits you wish to display on, and link the variable for the MI register you have your input linked to. I do not see any reason right away why the sensor you chose will not work with out controllers. Please ensure you have correct wiring, and test the signal with a multimeter. Let me know if this helps.

Hello, In U90, if you go into the Hardware Configuration and click the unit you are working with, you can set up the IO points. If you click on the Analog Input tab, you can link a memory integer to your analog input channel 0. When this is linked, you and then go to the project navigation and choose the "Memory Intergers" option, and choose the same memory integer you linked to the input. In this section, you will be able to linearize the value according to the bit resolution of that input. Hope this helps.

Hello, The V430s need to be powered off a 24VDC power supply, but the power supply is not built in. There are terminals built on to the unit for this connection. Hope this helps.

Hello Keith, To add to my previous response: I checked with our team and SI252 is supported with Enhanced series controllers as well. So you should have no issues. For your initial issue, is the MB not being set when the according screen is displayed? Would the "Is Displayed" bit in the links and jumps section of the HMI not a viable option for your application?

Hello Keith, I am checking with out team to see where and when SI252 should work. Just to be sure: you cannot get SI252 to work with your program in the V130? Is this correct?

Hello IanM, You can link a "Disable View" bit to the numeric variable. Then in the ladder, use a compare function block to say "if MI2 < 20, then turn on 'Disable View' bit". In other words, a 'less than' compare function block in series with a coil that is linked to the 'Disable View' bit. Let me know if this helps.

Hello, SI252 is only valid for the standard series controllers. The V130 is part of the enhanced series. If you go to the "Links and Jumps" tab on the HMI editor, you can link a bit to the display for an "Is Active" status. The bit will be on when the display is being viewed, and off for when the display is not viewed. Let me know if this helps.

Hello, You can use any RS232 device with the USB port. We do have examples of using RS232 with UniLogic in our examples folder, which you can download from our website or through UniLogic. However, I don't believe they specifically use the Panel USB port. To enable RS232 communication over the USB port, please navigate to the PLC Communications tab in the Solution Explorer, then the Physical tab, and choose the Panel USB Port option. In the properties window to the right, you can check off "Enable USB for Serial" option, and also choose the parameters for RS232 below the check box. In addition, the USB port already has standard drivers for a mouse and keyboard to be used with the Panel. Hope this helps.

Hello, These two models are pretty different, their main comparisons are really the size of the unit and that the are both color touch screens. Memory space is greatly different between the two. The V350s are for more complex and feature rich applications and big, whereas the samba are for simple and small applications. Some overall differences are: 1. Their memory space differ a great deal. If you do not need much memory, the Samba is perfect. 2. Expansion I/O: the V350 supports the local expansion adapter (EX-A2X) and the remote expansion adapter (EX-RC1), whereas the Samba only supports the EX-RC1 (via CANbus) 3. The V350 supports external storage via an SD card, whereas the Samba does not support SD capability. 4. The V350 supports web server capability, the Samba does not. Some differences specifically between the V350-TR20 model and the SM-35-T20 model are: 1. The HSI and HSO frequencies -- TR20 can handle 200kHz in, Samba 30kHz in. TR20 can handle 200kHz out, Samba 500Hz out. 2. TR20 contains relay outputs, the SM-T20 contains only transistor outputs (at 24VDC out). I believe these are most of the main differences between to two models. Hope this helps.

Hello Markus, When you installed the driver and plugged the device back in, did you cancel the "online search driver"?
