short story follows <Burn "upload project"> with version 9.8.80, install 9.8.65 and update all system files to that version and plc run normally after that. I tried to upload with success with only a warning message at the end that you are trying to upload a project from a newer version. It work! and it looks functioning pretty well (for now). GSM is back on line! (exporting hmi screens failed at importing) It looks that the problem is with BOOT files newer that 2.2.48. When having newer boot file the Siemens TC35i didn't initialize on any port. meanwhile I tried and version 9.8.80 with OS 4.6.15 is also working with BOOT file 2.2.48... so I could let the project in 9.8.80. thank you all, lesson taken

i will try, meanwhile if that work is it possible to roll back my project to previous visilogic version?

well, i did it but there was no change. meanwhile the new modem arrived and I take the cables as they were on V1040 and i put them on a V350, I use a typical test GSM example and everything works. i load that back to V1040 but looks that port 1 and port 2 are not responding to any initializing command.

Hi Aus, thank you! that is something that might be all. I 'll give a shoot soon and I 'll let you know.

I tried to do it without success. I connect it direct to PC Com port (once on desktop pc direct com port and once on laptop using usb-serial converter), from Visilogic's Modem Services I tried to do initiate it without success, Communication was not possible. i tried also from a serial terminal to command it without success again. I 'm not 100% sure that i did everything right because it's been a long time since I setup my last modem, but i think i did.

I did, maybe the problem is with the modem. I order a new one to check.

done that with out any success. i will have a new modem in a few days to check again, the old modem is not responding to AT commands, so there is something to wait for. ...but.. after loading a blank project the port 1 led is still blinking like there is data traffic, downloading back the original project, initializing COM 1 or COM2 is not possible again.

thank you all.every mistake is a big lesson.after trial and errors and files backup restoresNow I'm running visilogic 9.8.80 and system files are like theseV1040 (A)O/S: 4.10 (20)BOOT: 2.2 (53)BinLib: 0-3.10(03)FACTORY BOOT: 1.3 (06)it looks ok but I still don't have gsm function. the port led still blinking like crazy and it looks that it doesn't initialize Com 2 as it should.

you are right but i never thought that when got the new laptop to install the old software! I need also the bin and boot files that support the VCO00401036_V1040. and reload them all from the begining. doing that it might solve the problem. but from where to get them?

Hi Aus, thank you for reading my story the project was made for blank pages and works fine for 5 years. last mod with minor additions was at 20/12/20 and it was working fine. that's what I download again. what is strange is that when i update OS (VCO00401044_V1040)over ethernet and had the fatal error, i roll back the os again via ethernet connection (VCO00401036_V1040) and it boot and had a sms from the PLC that it was LIVE again, and it was fully functional. that's why i thought that might need also all the system files updated and I proceed with USB cable! now i have the 20/12/20 that was funtional 100% on the plc. that's the file i still have a backup with Visilogic v 9.8.80

Hello, is this a support forum or is a story telling website well I tried to download some changes after a while on one V1040... visilogic asked me to update the controler OS because it was old and I did. that result a fatal error on startup, so i deside to update it again using usb cable and not network connection this time. During bin.lib update i accidentaly lost communication and from that point and on all went wrong. with Unitronics Support I restore the controler with the lettest system files, bin, boot and os. I download the project and after that the fatal error was back! I took out the battery to zero the memory becasue the project was not burned and starting again with out application I download again the project. the fatal erros was there again so I deside to give "some time to the air". turn off the power, let the battery in controller and I went for a coffee. and it works! after power up the plc it boot ok and is fuctional but not 100%. the GSM intigration which was connected on Port2 has no communication with the TC35i modem. the led in front of port 2 are blinking, the signal is good and when i call the modem answer. so i tought to change the port from 2 to 1, i made all the nessesary changes on the program, swith the modem cable to port 1 and download, reset and run the plc. nothing! the problem still there. from visilogic's modem services i cannot acces the mode. it looks that com initialize doesn't work on power-up! the only thought that i cannot execute because i'm missing files. is to roll back everything. find visilogic v.9.8.80 where is the last project backup and all the plc system files that response to that but I don't have them. So in long that's the story and I ran out of ideas. any thoughts?

Is it necessary when you set the modbus in unistream like here?

I want to give a feedback and some more info because I found it difficulty .... well it looks that it works! the "words" reading is easier and clear approach. I don't have clear reading about Voltage of Phase 1, some times is around 230xxxxx... but most of the time is like 59139010000000000000000000.000000 but it's a stable reading. for Hz the reading is clear for both of them I can't find a way to move the decimal point. for example to have 49.84 Hz instead of 49837.520000 any idea how to manage the length of the values US5_B10_TR22 - v3.ulpr

Hi Joe, thank you for your msg. I'll connect it again to the modscan64 to identify the words... from there I can swap in real time from HEX to Bit and so on.... ... regarding the example you attached is something that i tried but I 'll tried it harder!

Hi, thank you both! So that's why I need a Gurus to guide me ORSO you are right that I miss that point and Isakovic stretch me to the reading of several registers in row. I made some test, here is the code but still don't have the correct result. correct me if I'm wrong: 0x12345678 Reg 0 - Hi is 34 | Reg 0 - Lo is 12 | Reg 1- Hi is 78 | Reg 1 - Lo is 56 the format in order to be read as float should be 34,12,78,56 ? what I tried to do in the attached is that but is not working they are 2 lines here, one with Sargani's explanation that looks pretty nice and give in "Buffer 1" the above format, but I'm still missing something to have the right result the second is a deferent approach but also half and far way. thank you for you patience.
