    I did quick fiddle with the data in Excel. It looks like an offset of -45 counts and then a linear scaling error of -2.4% over the range of the input. Fluke(ma) Actual Count Expected Count Count Diff. Data without offset Percentage Error 4.000 -45 0 -45 0 6.000 954 1024 -70 -25 -2.44% 8.000 1954 2048 -94 -49 -2.39% 12.000 3953 4096 -143 -98 -2.39% 14.000 4957 5119 -162 -117 -2.29% 16.000 5951 6143 -192 -147 -2.39% 18.000 6951 7167 -216 -171 -2.39% 20.000 7949 8191 -242 -197 -2.41% I would not expect this as normal behaviour. The spec sheet gives accuracy of 0.4%. However, apart from the offset and scaling errors, the data looks quite clean. Usually a bad input won't even perform this well. Were you able to test with the field wiring completely disconnected from the analogue module (that includes the commons as well as the signal lines)? I notice you are a few versions behind on UniLogic, the current version is 1.28.34. I doubt the issue is version related, but I would suggest upgrading at some point. I'd be pushing into a more thorough diagnosis of the hardware and field wiring first. Hope this helps,

    OK the operational state means that the PLC is unable to talk to the URB(it's not establishing a connection) 0- Establishing Connection (in Progress ) When you pinged the URB was that from a PC or the UniStream?? 1)Trying pinging the URB from the UniStream via Uniapps->Network->Ethernet->Ping 2)You've set IP address for both the panel and CPU(your PC will use the Panel IP to communicate with the PLC, the PLC will use the CPU IP to communicate with the URB) 3) Is it an isolated URB and PLC are on an isolated network or are you going over the top?? 4) how did you set the IP on the URB?

    You'll need the Ethernet port. If you have a router visible from the outside Internet you'll need to port forward port 20256 in the router to the IP address of the Samba. The USB port is for programming only. It's doesn't have the capability to be a master and drive an external device such as a WiFi stick. Joe T.

    Hello, I bought a new laptop a few days ago and had the same problem for both U90 and Visilogic. I restarted my PC after installation and problem was solved for both software! Best Regards, Kikis

    This is not a question, but a issue that has been soved that might be usefull to someone else to avoid pain. V1210 V9.4 Visilogic Windows Vista 32 bit The initial problem was that my communications on com port 2 (my VFD connection) is always perfect with no issues, but as soon as I turn on a VFD (variable Frequency Drive) the communication between the PLC and a computer instantaneously and permanently stops until such time the VFD is stopped (not powered down) and then the communications can be re-established to the PC. I have tested out just about everything I can to make sure that the answer is correct and not accidental. 1) I have an RS485 with termination using Modbus RTU protocol on com port 2, 19200 com speed 8,2,none connected to a FUJI brand VFD 2) I have com 1 at the default 232 connection to go to the computer using a USB to serial adaptor the has been in constant use for 2 years and never had any trouble (cable from “cables to go” the model is 26886) 3) I have tried shielded com wire both grounded and ungrounded. (no help) 4) I have altered the output carrier frequency of the VFD (Higher the carrier frequency on a VFD the more electrical noise is generated) (no help) 5) I have tried with a motor connected and not connected both with and without grounding. (VFD wiring to a motor can act as an brodcast antenna) (no help) The answer is the USB to serial cable that has and does work when no VFD is running is the root cause of the condition. I have other USB to serial converters and have replaced the original with a metal cased USB-COMi-M that was purchased from www.byterunner.com for $59 and when using the different USB to serial adapter everything works smoothly with no issues under all conditions. I have also run direct to a 9 pin serial port with the standard programming cable and all communications are perfect with or without the VFD running. I think I can correctly and safely say that nothing in either the Unitronics hardware or software is to blame for the troubles I have had. It has taken me most of a day to figure this out so I figured I would pass the information on since it might be useful at some point in the future when someone else has a similar problem. Keith

    Yes. You'll have to send them a text from within your ladder logic. Vision series Email blocks are not capable of using an email server that uses SSL, so you'll need to set up an account with a non-secure email server. The only public one we know of that can still do this is SMTP2GO. Look at the Example project for Email on how to set this up. Check out this post- Joe T.

    Hi and welcome. Before doing anything else, did you do the install as right click/run as admin? And once that is done, go to the U90ladder.exe program itself and ensure you have Run as Admin selected in right click/Properties/Compatibility. If you did not do the install as above, save your plc programs, connect the plc and manually fully delete the matching com port driver in Device Manager, completely uninstall U90 using the standard uninstaller, then delete the Unitronics U90 Ladder folder if it remains, reboot and start again, doing the install as first mentioned. In theory the latest versions of the program do the admin stuff themselves, but sometimes it doesn't work. Once you have done that, see how it goes and then we'll proceed from there. cheers, Aus

    Hi all, This Topic will list items that are worth an easy find, but are not quite "pinnable" on their own. If we pin everything that is useful, it will all become one big mess on page 1 (or bigger!). I suggest that if you want something added to the list, contact myself or another mod to have them edit it into this existing list that I see as having carefully considered updating. To save space, only links will be shown, not full previews, with the Header or a Description listed before the link. Sometimes the link will take you to a particular post within a Topic that is the answer, but a full topic read will never go astray....history is useful.

    The "plugged-in" aspect of the laptop is VERY important. When you're on battery, everything is isolated. When you're plugged in, the negative of the power supply and everything else (including the USB port) is grounded through the neutral and that will often kill communications. Joe T.
