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 restores
Now I'm running visilogic 9.8.80 and system files are like these
V1040 (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
-
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.
-
Hi Joe,
yes I did, I also checked two other post from the forum.
1.
2.
but as far I can understand is that the reading should be in two arrays or two registers. how ever I was not able to read two arrays from unistream.
according to the energy meter's manual they are 4 bytes (2 registers) per parameter.
http://support.innon.com/PowerMeters/SDM630-MOD-MID/Manual/SDM630-Modbus_Protocol.pdf
if I connect with an adapter to the energy meter with modscan64 I can read the values also in float format
When is saying 4 bytes (2 registers) they are 2 registers in row?
for example 30001 and 30002 ?
p.s I'm beginner in Modbus but I think not that bad
-
Hello ,
I 've got an Energy meter (yes again!) which returns 16bit registers at the maximum range 65535. some times that is also negative... that is format IEEE 754
It's the first time see this format and I can't find a way to read automatically the correct values.
I read some articles and some other post with multi array but this is not multiarray it's just a number which need some calculations on it if I got it right? (find the "mantissa" and so on).
Or I got it totally wrong ...
any Ideas ?
thank you
p.s I 'm using a US5-B10-TR22
-
Hi,
I have exact the same problem but I'm using unistream US5-B10-TR22 and I really can find a solution.
is there anyone to give a hand
-
respect!
analog is something new for me and I looked in the help before that but I didn't got it right.
for example. how do I know my input resolution if it's 10, 12 or 14 bits? is that plc hardware or it has to do also with the sensors?
thank you for your help!
-
Hello,
I got a V130 -33-TR6 to read some 4-20mA analog sensors.
It looks that the input MI doesn't response on what I had in mind. The values for 0 (Zero) instead of 4mA is 206 in the selected MI and the linear conversion is hard because it looks out of range from the very first time. At the Current Transformer for instance there is no current flow and the result should be 0 Amps.
the sensors are 2 wires. so the (-) is going to the input and the (+) is going to the 24V
check out the sc shots.
what do you think that I'm doing wrong?
-
Hello Joe.
thank you for your effort! it was really helpfull.
actually it worked like before, no matter if the input was in the list it returns 0 at MI1302.
if the msg was not recognised it returns like you said -1.
however the scan like you said it's working but it was always stopping at first index where it was getting the received message to fill the variable in MI 1310 .
That's why as far I undrstand it was returning always the 0.
I change the protocol scan and I keep the row where transfer the received msg to variable MI1310 at the end. so the received msg pass from all the rows before go to that row. It works!
now MI1302 get values like 0 for #0000* , 1 for #1234* and 2 for any other valid format msg
thank you very much once again for the support.
-
hi again,
i didn't have any luck with the scan yet. any other idea?
i thought that would be easier if there was a way to read the string and compare it with other but how can this be done? something like a manual scan subroutine
-
it looks that no matter what you chose the MI 1302 stays on 0.
that means that it doesn't scan at all.
can I make a subroutine that will read the MI1310 - received string, and match it with string that will raise a mb?
-
I made some modifications on the last version.
I add auto reply the received message and i modify the protocol by adding some index. ( i used ..\Project examples\Strings\V280_Receive_number_and_string.vlp )
following that index i tried to raise a mb at line 4 , but did'n work.
(more or less i had in mind the configuration of a SMS CONFIG but as far as I know there is no such function in that case)
what do you think?
-
It works. Thank you both of you.
It seams that I have a lot to learn

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
