  1. Problem solved..... First created a back-up of my Unistream configuration. Then I removed all configured remote I/O modules (EX-RC1's), except the one physically connected to the Unistream. Downloaded new configuration and the outputs reacted immediately. I hope that problem was because of undetected EX-RC1's and not just because of the number of EX-RC1's . I guess I'll find out once I get the entire system connected.
  2. Hi. I have a project that includes a Unistream controller and 9 EX-RC1's. I have followed the recommended procedure to set-up each EX-RC1, and Unilogic. The Canbus baud rate is set to 500Kbits/s I currently have the controller and one remote station at my desk for testing. I can toggle the remote inputs on/off and see the immediate status change while online monitoring. When I switch an output on, I see the PLC status immediately change, but the actual output is delayed by anywhere from 1 to 30 seconds. The same applies to switching the output off....immediate status change in the PLC, but huge delay to actually switch off the output. I have monitored the in the EX-RC1 "UniCan M. Arrived" and it seems to be receiving this signal approx. every 40-50ms Could the delay be because I don't have the other EX-RC1's connected? Is there a quick and easy way to temporarily disable the other EX-RC1's in Unilogic? I don't want to delete them all and have go through re-configuration again. I have attached the exported file from Unilogic and also the file that is in the EX-RC1 any help is much appreciated dave JB900-HW Export.ulri JB900.vlp
  3. Hopefully you've already figured this out, but just in case you haven't.... If you want to prevent other programmers from seeing a particular screen configuration, you can right click on the screen name(in the Solution Explorer), then select "Password Protect" If you want to prevent unauthorized access to the screen during operation, you can assign a button on another screen("Main Menu", for example). Then, in the Properties Dialog box for the button, add a new "Load Screen" Action, then set the User Access property. In the Solution Explore, use the "User Access Control" to configure the different levels of access, as your application requires. I apologize for not being more detailed, but I am also a new to the UniLogic platform and just started looking into the whole password protection/user access system. The more I learn, the more I like!
  4. How many degrees from vertical can I mount a USP-156-B10? I couldn't find this detail in the installation guide.
  5. I had a similar situation and found the file copied to the DOK was corrupt. I repeated the procedure to copy the new firmware to the DOK (using the Unistream Management|Firmware Manager on the PLC tab of the ribbon) , and then re-booted the HMI with the USB stick and it fixed the problem.
  6. Thanks Henny. That's pretty much what I ended up doing. Except I used the same offset(0), and used the insert option instead of overwrite, for the "copy tag to buffer" instructions. I was hoping for a single "convert"instruction where I could specify the source tag, offset & length. The bar code reader(which is what is sending me the HEX data) has a nice feature that allows you to select byte swapping via a simple checkbox, so I didn't need to concern myself with that task.
  7. I have 6 consecutive INT16 type tags that contain 2 characters each of ASCII characters in HEX format. I would like to convert/concactenate them all to a single ASCII type tag. Is there a simple way to do this? I couldn't find any conversion instructions and the sample project I looked at (UniStream_070_Num_To_ASCII) seems to be an incredible amount of code to do a simple conversion.
  8. Problem solved.....I was doing everything correctly. The bar code reader was not functioning properly though. After a reset to factory defaults(including clearing the ip address) and reloading the configuration, it mysteriously started behaving as it should.
  9. I configured a VNC Client using Connection 0 and configured a password "PLC". I am able to connect, using a VNC viewer application, from both an I-phone and a desktop, but in both cases, no password is requested or required. Is this a bug, or am I doing something wrong?
  10. Does anyone have any experience using a Unistream to communicate with the SR-1000 bar code reader? I set up the scanner node on my Unistream. I set the bar code reader's "Data Transmission" parameter to "Send After Read" When I monitor the input assembly status on the Unistream, I can see the I/O status, along with various other status bits dynamically changing, however the actual read data does not get transmitted. I wrote some code (10 lines of ladder logic) to send a Reading Start Request ( by manipulating the value of the output assembly registers) and can now get the read data transmitted with every successful read. (I still haven't figured out to convert multiple words of HEX data into a single String type tag) This is my first time using Unilogic and Ethernet/IP. It seems to me that I shouldn't have to use any ladder logic to accomplish a simple read data update. Should I keep trying to figure out how to do this without using ladder logic, or am I chasing a non-existent solution? ( I tried to upload my test project, but the file size exceeds the limit)
  11. Well....... it didn't take too long at all before I came across a need desire to transfer data tables to DataXport, more than once per minute! Client has DataXport set up to listen for calls from V570. These calls happen approx. twice every 8hrs and transfer one data table for each of two machines. The client cannot ensure that DataXport will always be open and the configured application running, so I added PLC logic to monitor the data transfer and if the transfer fails for any reason, the data table is saved to SD card. After a weekend with the DataXport being down, the SD card can accumulates up to 12 or more files. The client can later access the SD card using a "Variable: Browser SD Contents" screen object, and using the "Send file" feature and some additional code, initiate a call to to transfer each file to DataXport. Transfer time per file is about 2 seconds.....however, I must force the client to wait for 1 minute between each file transfer to avoid DataXport overwriting a previous excel file. Time standing at the machine, 12 minutes, instead of 24 seconds. My only solution right now (although I'm certainly open for suggestions), is to write some code that allows the user to press a "Send ALL" button, then automatically send each file, one at a time, every minute. It would be SO much nicer if I could customize the filename structure that DataXport uses when creating Excel files........but if that's too much to ask, maybe DataXport could add a "_1", "_2", "_3", etc. at the end of the filename structure it already uses?
  12. Thanks everybody...this topic helped me resolve my folder(s) issue without having to ask for help!!!
  13. Perhaps you could check that the firewall on your PC allows incoming connection from DataXport.
  14. Yes, I tried many times with no luck .....until just now. I found that when the dialog box opens after selecting "Project > Excel/.csv File Properties", the folder(s) that I created are displayed. I had them created on my C drive, but..... I found that none of the other folders on my C drive were displayed, nor could I browse to any other location(s) without first selecting one of the other drives listed in the dialog box.( I never did this before because the other drives displayed were CD & DVD drives that I knew were empty) Then, when I select the C drive again, I am able to see and browse through all the folders on that drive, and select a new location. Don't know if its a glitch or an oversight, but at least I now know how to work around it. Another discovery I made was regarding file names of the Excel files created by DataXport. The file names are created based on the following format: "Site Name\ structure name.table name_DD_MM_YY_HH_MM.xls(x)" When I transfer a data table from the PLC to DataXport more than once in any given minute, DataXport will overwrite the previous file because the file name format ignores the "seconds" This is not a major concern for my current application, but I can see it being bothersome in the future. Now that I have a "taste" of DataXport, I'm sure I'll come across an application later where I'll want to log more than one data table per minute.
  15. Does anyone know of a way to change the location of the folder where DataXport saves the Excel files it creates......without creating a new project?
