  1. Hi, I am working with a 15" UniStream series PLC. This PLC has modules on its backplane(3xrs232 COM + 2xUIA-0006) and other modules added with two UAG-XKPxxx expanders.First expander(6xUIS-0800TC), Second expander(2xWide digital + 4UIA-0800n) The problem is that when I download the project into the PLC, it gives me an error because the App i/o configuration detects the UAG-XKPxxx modules but then PLC cannot find them. However, it does find the modules added after the expander. The project was developed in version 1.35 and has also been tested with the latest available version 1.36 Any ideas? We have downloaded the IOS files to all the modules, wiring checked...
  2. what about help files updated with the news functions, i can not find some info about new or "olds" (non native) functions like "Insert to String"...
  3. We can not modify the sampler pcb, actually we are working with unitronics support trying to find any solution. If we can not find a software solution, we will implement a raspberry as echo device. Receiving commands from PLC and sending throught other port to sampler, could be work i guess. Thanks for your info, i'll update with the solution given finally.
  4. Thanks for your reply Joe, The autosampler just has a single type B USB port. I will ask to the autosampler supplier about a prolific converter in autosampler instead ftdi one installed already. I’m thinking to put something like a bridge ( imagine from USB unitronics-prolific232converter-prolific232converter-USB to connecting Autosampler usb port. Could work? I will test this idea tomorrow. An other idea could be installing UAC-02rs2 comm module and connect directly a Prolific232 usb converter and connect it to autosampler port.what do you think? thanks for all your info, BR
  5. Hi engineers, I have to communicate with an AutoSampler, it has a RS232 Virtual Com port vía USB. This serial-usb converter is a FTDI chip, so here are my problems; Trying to communicate trought- PANEL USB and cable directly. It does not work, i always recived -1 on status Tx. i was looking for any information about this and I have seen that Unitronics recommend Profilic converter but this AutoSampler has installed and FTDI , how can i communicate with it directly, like on my PC, with my PC i can send commands via terminal and everything works properly.
  6. Hi all, I have doubts about wich control architecture would be appropiate for a project that i have on development. I'm thinking to work with a single HMI+CPU as main hmi control and distributed I/O signals using URB Adapters + I/O Modules, cause i have to do six equipments with same characteristics: Digital Input: 4 Digital Output: 5 Analog Input: 8 (current) Analog Output: 3 (current) Thermocouples: 8 Comms: 1xRS232 + 1xRS485 My main doubt is I've never worked with the URB Adapters, but i guess this project is a good option for them. So the architecture should be something like this(*Comms Modules could be attached on HMI+CPU): I know there are many options and configurations, but lately i'm facing some problems with delivery time on UniStream Local i/o modules, so i want to give a chance to UniStream Remote family. What do you think about the architecture? Any information or feedback will be appreciate. Thanks, BR
  7. Hi AlexUT, Thanks for your answer, of course always all information given is usefull, so thanks for your help. Just i asked cause i want to control some digital outputs as pwm for heating process. The heating procees is slow so i don't need a fast response on my pwm but i wanted to know what is the fastest frequency that i can implement in a normal digital output. I'm going to assume that the maximum frequency will be around 10kHz so that it is slower than the maximum switching time (80μs - 12.6kHZ) Thanks,BR
  8. Hi all, I'm looking for digital outputs maximum frequency value in UID-0808T and UID-W1616T modules. The technical specification pdf just shows "Turn on/off switching time (80μs max)" so is that frequency the maximum for normal(no highspeed) digital outputs , activated as PWM or normal state? BR
  9. I'll try it, but it will probably work i guess. I was wrong about Reset pid autotune, I thought that this FB resets the internal values of the block and i usually used it before starting the autotune process instead at the end of the autotune process. Thanks for your help, BR
  10. Hi all, I usually work with PID loops and tunning it manually. This time i want to try the autotune feature but i'm facing some troubles with the autotunedone bit in "PID Config" struct. This bit when autotune is completed is always ON and the help file says "Reset by user"... Well this bit is not possible write on it cause is a reading bit. So could you tell me how to reset this bit after autotune is done? If you start the autotune process again the autotunedone bit is reset by itself, but i want to reset it before start autotune process once again. BR
  11. Really apreciate it cause i'm working on quite a few projects with these models right now. Best Regards!
  12. Hello, I'm facing a visual problem with the Alarm banner display on 15" HMI Panels Unistream models. It's like the text field is not resize for this models. I attach a picture. Some ideas about this?
  13. Hi engineers, I'm working with a US5-B5-RA28 PLC, i would like to known the meanings from "On board IO.IO" error codes, cause i'm facing some issues with this plc model. This PLC is running but sometimes the PLC gets On board IO.IO Status = 16 , after that all the digital outputs are freeze with their last state and the analog signals have wrong values, but the HMI go on working OK Any ideas? Thanks Cheers.
  14. Hi engineers! We can't implement this kind of contacts in the UDFB´s, so could u tell me how can i simulate type of contacts inside my UDFB?? Regards.
