Hi; I did have a Blank program in the PLC before I did the Upgrade - Found that our a few versions ago, best to download a blank program into the PLC and recycle power before doing the upgrade. And Yes, having the older version of Univision available on another computer is very handy during the process. Dan

Hi; I upgraded my 10 inch UniStream to the new release 1.8.51 and have a couple of things to share : The upgrade in OS in the PLC had a problem and restart got stuck in Initialization. I got mine recovered and let support know what I did, Maybe support should inform us the "better" way to do it. In my program, I have an Imbedded Data Table with data preloaded- a lookup table. During the upgrade from old version to new version rebuild, the data table was either wiped or not rebuilt. I ended up going to another computer with the older UniLogic, saving the data table to an Excel file and then importing the file into the upgraded project. Just to note also : imbedded data tables with fixed data are not automatically downloaded to the PLC during a download. They have to be manually loaded. Dan

I too had similar issues with setting up Visilogic in Windows 8. What I finally did , and got things to work was to change the security properties on the Visilogic.exe in the Main directory. Be sure you have Administrator Permissions C:\program files\unitronics\unitronics Visilogic_C\main ( yours may be slightly diffferent) Right click on Visilogic.exe goto Properties on the Dropdown First open the tab for Compatability and check off fo rWindows XP Mode and also click on the Change settings for ALL users. Second open the security tab examine the security settings for each user IF they doe not have FULL Controll as ALLOWED, edit the user to give FULL CONTROL I also did this to the Visilogic Version Swapper.exe Once I got this done. I used Visilogic Version swapper to setup the version , the program worked. I even managed to get 3 versions of Visilogic Loaded ( 9.5 9.6 9.7) and functional thru Swapper by making sure the Visilogic.exe security settings were changed. Another note : I also had to change my USB-Serial Adapter cable because the drivers for my other ones would not support Windows 8 ( Some Prolific Chip versions will not work with Windows 8) Ended up getting a cable that specified to was compatable with Windows 8 and it works Dan Thomas

Hi James; On the Meter Graph, there is no provision to add labelling. You will have to do the labelling manually with Text and Numeric Elements. Dan

Hi James; In the Properties Block for the Button ( Lower Right Part of UniLogic Screen) Look for Actions( normally at the top of the List) and open Then Add New Action -- Set bit and link it to the ladder variable. You can Set the Ladder Bit when button is pressed, and reset the Bit when button is released (or do the reset in the ladder) Actions can also call Screen jumps, set VNC Connection, and others Dan Thomas

Hi; I am using this VNC program : http://www.realvnc.com/download/viewer/ Download the version for your computer OS Put it on the desktop. There is no install program, it just runs when you open it. It will ask for the IP Address, try 204.225.158.195 : The connection is NOT Encrypted -- This a is a UniStream I have hooked on the Internet It has the Unitronics Unistream Demo Program with a screen I did for myself ( it has a UID-0808R and a UID-0402N Modules attached feeding outputs back to inputs) You can operate the screen like it having the PLC in front of you. If I see that you are online( The PLC in on my desk) I will interact with you. What we also found out is that more than 1 can be on at the same time -- an interesting feature for some applications. It will be up for a a day or so. You cannot see the program or the logic. Questions for Unitronics Support: Can this be made into a secure connection? How? Is there a way , other than thru Unilogic to view the variables like in Remote Access in Vision Series? Dan Thomas Sandtron Automation

Thanks for the Reference; I have the V130 now reading the data properly and getting the encoder position. Anyone done a CRC-CCITT X16 + X12 +X5 +1 ( Seed 0x1021 ) CRC subroutine? There is an example of CRC calculation , but not for this Dant

Hi; Any one have experience working with a Wachendoef WDGA 58B Absolute Encoder Multi turn transmitting data via RS485? V130 Com 2 Dant

Good Day ; Has any one used the Function Blocks under Protocol TCP/IP To communicate to an Allen Bradley Micrologix PLC? Does Allen Bradley use a special TCP/IP Protocol? Dan Thomas
