Hi, I consider few ways to get 100 variables every second from USC-B10-TR22: 1. Create DataTable on SD card, and then get it through FTP server 2. Get data via MODBUS 3. Use any OPC client When I tested first way, there was problems with accurate timming. I forced creating line in SD file with data every 0.8s, and average time was around 0.8s, but varied between 0.6 and 1.4s Second way seems to be ok, but using Python's modbus library also occured some timming mismatch. Average was also ok, but again varied between similiar values. I'm not sure, but it -
Hey guys, I have a UniStream 7" PLC connected with EX-RC1 expansion module via CANBUS. The CANBUS is connected according to the info in the datasheet with 120 ohm resistors and everything. The complete configuration that the PLC communicates with from left to right is as follows: EX-RC1, 3 x IO_D16A3_RO16, 2 x IO_ATC8/AI8, IO_D16_A3_RO16. The PLC and the EX-RC1 is grounded and connected as it should. EX-RC1 is programmed (initialized UniCAN) and the LEDS are all working propperly (PWR ON, I/O COMM ON, BUS COMM ON). Accordingly I am able to read/write all the inputs/outputs. So,

Working with a new but older Unistream 10. Had to update firmware to be able to download a sample project. Successfully did one go around, apparently had to do it again according to the error message. Was using USB stick to do it. Worked fine the first time, but the second, after reboot, screen is blank and can't communicate via Ethernet or USB. Can't get into the back screen utility either. Suggestions? TIA -
Hi, I'm not sure about phrase in manual of URB-TCP, which says: "The adapter is limited to process 192 data bytes for inputs and 192 data bytes for outputs." Does it mean thah when I use 192 bytes as inputs, I can still use 192 bytes for outputs? Please let me understand it well, Greets, Damian

UniStream: rising to the COVID-19 Challenge
Cara Bereck Levy posted a blog entry in Unitronics' Blog: PLCs, HMIs and more
Hi people, In the here and now, engineers save lives. Medicavent rose to the challenge of COVID-19—ventilators. They did it using a UniStream Built-in, model US7-B10-TA30l. As they tell it: > Our team, composed of aeronautic, mechanical and systems engineers, whose day jobs are working on classified defense contracts, have decided to rise to the occasion, working around the clock and under the radar to develop a semi-professional ventilator. The criteria selected were rapid development, production scalability, reasonable cost, meeting the strictest standards and m -
Hi all, This is an open invitation for you to suggest new ideas and thoughts for Unilogic UDFB's. It is very important for us to keep track of our customers needs. As part of this agenda we want to create and develop useful tools for your benefit. These UDFB's will be attached to the next releases of Unilogic. Please feel free to suggest any idea that seems useful. Thank you

Hello, I have Unistream 7 and I have problem with configuration of high-speed output of module UIS-WCB2. The high speed output 0O should be able to be configured up to 250 kHz using PWM mode. According to help, I have configured in properties windows HS Block 1 to PWM - see screenshot. Then I have configured the struct B1 according to the screenshot, but it still does not work. The classical "slow" output using function PWM worked, however I can not get to work the high-speed 100 Khz+ output mode. Thank you very much for any tips. Best regards, Martin Sirovy. -
Good morning people! I'm experiencing a problem sending emails with an UniStream USP-070-B10 programmed with UniLogic v1.28.26. When I request to send an email, the email is correctly sent, but the content of it (body), appears as an attached file. This started happening some months ago, and we don't know why, because before it was working perfectly. Does anyone know what could be going on? @Cara Bereck Levy Thanks in advance, Gonzalo!

Hello to all, I am working on a new system where a Unistream B5 TR22 is a Modbus TCP master to 11 Samba PLC's Nothing to exciting but my biggest problem is a lack of knowledge. This is only my second project with a unistream PLC, with the first being a very straight forward ladder program without anything special. i do have a few years of experience with visilogic so that side is not a problem. What i already figured out is how to make the set-up on the master and slave side. the thing i don't get is addressing between the devices. In visilogic i could literally select which mb,mi,ml -

Dear colleagues, I'd like to share my first project using Unistream. It consists in a test bench for an important manufacturer of industrial HVAC systems and compressors in a new factory in Spain. When a new compressor is finished in the production line, it has to pass the test bench in order to be suitable for selling. These compressors can reach up to 250 KVA of power in 50 or 60 Hz and there are three independent lines: - The first line is for machines from 200 to 460 volts in 50 and 60 Hz and up to 250 KVA. - The second line is for machines from 12 t

Hello! I have a problem with COM-ports on UniStream. After simplified configuration MODBUS on RS232 function COM-ports RS-232 modules UAC-02RS2 not activated. What is the problem?

I use Com port 2 to Modbus, Com port 1 i want to use to a modem. But as son as i change Tx/Rx to Modem the Modbus communication at Com 2 stop, when change back to Tx/Rx and repower, Modbus work again. Should this work?

I am working on a Unistream Project that will use an EX-RC1 module with an IO-AI4AO2. Does anybody happen to have a Visilogic example File for this configuration?

Hello I am using modbus RTU Reading two sensors. Modbus ID = 1 & 2 respectively. From each sensor i read two values, one 16bit and one 32bit float. Baudrate = 9600. When I activate communication using "Active periodic" bit any one of the sensors (only) I can set my update interval at 100ms without having failures. The "funny" things occur when when i activate both: If I set my update interval at 400ms: It updates values from both sensor for a few Seconds (at 400ms rate), then it stops completely updating the reading/values from ID2. But the "success" Counter continues

Eurotech had previously used Unitronics Vision series all-in-one PLCs to control their extrusion equipment, but had started using a competitor’s product. However, they switched back to Unitronics products following the launch of the UniStream line; these modular, all-in-one PLCs offer a flexible, easy to use control platform. Eurotech uses UniStream line, 7, 10, and 15" models . Read all about it here: https://unitronicsplc.com/testemonials-category-carrousel/?category=miscellaneous&tid=10406

UniLogic Tech Tidbits - the Movie!
Cara Bereck Levy posted a blog entry in Unitronics' Blog: PLCs, HMIs and more
If you haven't checked out the Unitronics Youtube for awhile, you may want to check out our UniLogic Tech Tidbits Playlist. The most recent Tidbit shows you how to create your own, reusable HMI Custom Controls. After you create a control, you can drag and drop it from the Solution Explorer, export/import it between projects as .uluce files, or add it to the Library. You can also define tags that are local to a specific Custom Control, these tags will be exported/imported along with the control. It's all in the link below! -

Hi all, Question: Is it possible to turn the backlight completely OFF in Unilogic by ladder?If I try to control the brightness by ladder; Actions - > "Change Brightness" and link a UINTThe help-file states: So this seems to be normal behavior. But if I use Uniapps -> Display & Audio; Sliding the brightness-slider to zero, does turn the display completely off!According to Version Changes, this is the case since Unilogic 1.8.51, Unistream OS 1.8.9, October 2014 Nevertheless, it would be ideal (for me and others too I think ) if we could get complete control over the back
