  1. Hi All Has anybody had the following issue losing MI Values in programs all reset back to zero for no apparent reason have not set MI to change to zero on power up have cycled power numerous times on plc doesn't do it, not anywhere in programs am I resetting. Happening at 3 different sites, completely different programs. One site happened 2 years of running fine after install. One was running off of generator supply. Only happens to MI that are either keypad entry or used to manipulate data in the program. Using switch mode power supply to power plcs, have replaced backup battery even though not getting battery low alarm SB8 Still happens - only common thing across sites is that they are either out in the country or at a mining site powered by generator.
  2. Thanks s.pratt We went down that path after we posted on the forum we were trying to be too clever (not normally a problem) and use protocol scan but that only seems to work when matches complete string.
  3. Hello... We need to parse a text string to search for a single character within the string. This will then be used to trigger an SMS output. The incoming string is variable length with the last part also unknown content. The string header is known format. The terminator, (ETX) is 0xOD 0xOA, (CR LF). We can successfully scan a properly, fully, defined string however we cannot figure out how to simply look for the first character for example find "A" in the start of the string or deal with a variable string. Also once we see an "A" in the start of a string we still need to copy the entire string from the buffer to memory. Any ideas or input is welcome......
  4. Hi All Im working on a project that requires a v570 to communicate with kepserver using modbus ip has anybody achieved this and if so what settings were used for both the v570 and kepserver Thanks
  5. Hi all Has anybody been able to get a unitronics V570 to communicate with Allen Bradley Factory Talk Se Scada.
  6. Hi all Is anybody else having the problem of getting the a corrupt file message when trying to open a save program using version 9.3.1. If you open the file with a previous version say 8.6.3 it works?
  7. Hi Ofir In the process of setting up a demo plc which I will give you remote access to Thanks
  8. Hi all I have a V570 its been on site for 1 year, twice in the last 2 months Ive had an expansion error when someone goes there all the card run lights are solid is there any SB or SI that will tell me which card is causing the issue also would be nice if you could automatically reset fault so plc starts up again. Thanks
  9. HI Would be nice if you could link a timer to the trending sample interval making it easly adjsuted remotely.
  10. Hi All Currently have an issue with remote operator have a V570 850kms away connected via ethernet through a vpn and 7.2mbps modem, ping is around 300ms, works fine until I display a hmi page that has a plant overview with lots of icons and variable data the icons and data come up with red boxes have tried changing the refresh rate currently at 60 secs that has made it better still get red boxes with crosses in them but they do disappear before the next refresh. I want to know is there any way so that remote operator doesn't refresh page until it has all the data so I dont get the red boxes. Thanks
  11. Thanks Simon Thats exactly what I meant, should learn to be more descriptive, had a V570 go into fault expansion card error was able to reset via ethernet modem. Little bit concerned as some of our V570s are on remote unmanned sewerage treatment plants would like the plc to try an automatic reset even if its gone into stop mode.
  12. Hi all Is there anyway of resetting a plc fault and putting plc back into run automatically say by setting a SB in the program on startup Thanks
  13. Hi all Is there any way to hide the V570 Info password (SI 253) so you can't see it in the program or if you go online?
  14. Hi Has anybody used the broadcast function for modbus ip with success, have tried using the setup as per the help files cant seem to get to work? Thanks
  15. HI Because lots of our plcs are in remote areas we have to make changes remotely, unfortunatley I have found doing a burn to memory is fraught with danger if something goes wrong and no one is there. It would be great if when you download without burning the program in the flash is not effected, so if the backup battery goes flat on the next power up the plc loads the flash memory program basically two differnt programs in the same plc.
  16. Hi all Is there any way to turn off the information mode, be really handy to set/reset SB to do this because if you use remote operator and click the mouse too long V570 goes into info mode which is not supported remotely anyway. Thanks
  17. Thanks Emil Looking at a 3G option to replace the existing gsm modems (wavecom,siemens) still need to use rs232 as the primary function is to send out alarm sms, always nice to get quicker speed for remote access though. As the modem needs to use one of the com ports starts getting ugly to try and get modems that aren't supported to communicate with unitronics.
  18. Was wondering if unitronics had any plans for supporting a 3g modem as it appears here in Australia that the largest telco is starting to shut down parts of its 2g network meaning that all the exising modems are only going to be good for paper weights?
  19. Hi would like to see the times in the drum sequencer being able to be linked to timers so you can change the times online easily, its annoying having to change the times then download the whole program if your using V530 ect.
  20. Hi all help I currently have a V280 with Ex-1A adapter IO-AI4-AO2 IO-DI16 IO-DI16 IO-R16 Been running fine for years now is coming up with V5.4(B09) HW A Expansion Error 1 0x0000 2-0 3 0x0008 4-0x0000 5 0x00000000 can anyone help with which expansion card is causing the problem turn off power and starts up for up to an hour then faults
  21. Hi all having an issue with visilogic version 8.6.3 when I use the modem services and try dialing a modem using tapi I get the following errors before visilogic shuts down UnVsCon1 Runtime error '-2147213294(80042012) Lineerr_Invallinehandle followed by Runtime error 440 Automation error Any ideas how to fix running windows xp has been fine for years before this.
  22. Thanks Simon Tried laptop with serial port worked fine, have ordered converter from you
  23. Hi Ofir Have had the problem on jazz, V130, V530 and V570 yes Im using the latest os, first thing I do now is check os have had that drummed into me by our unitronics supplier Im using 8.6.3 It fails the initialize pc side modem check then if keep trying might get lucky and will initialize Have taken the pin off the sim Unfortunately the sim provider is the only one with decent coverage where we install these modems might try one of my work mates sim card out of their phone different phone company to try and prove thats were the problem is. Have had some out in the field work for years others work great for weeks then starting having issues.
