Hi there Is there anyway to set a maximum time limit to allowing a remote access connection to be open for We are on a 4g connection etc all working normally but 1 of the operators keeps forgetting to close his connection, using up all the data So I was hoping there was a way to do this either in PLC ladder or from the Remote operator app? I am using socket 3 set up to 20256 I have tried a timer running on socket 3 connected, that once timed out forces the socket closed, until socket is no longer connected, I have also forced closed for 30s However once these timers elapse remote operator just reconnects and carries on usually with prompts on screen

Thanks for the reply, yes my sample projects attached work great, I have 2x sambas on my desk for testing, i split the registers up like that to simulate reading from multiple slave devices across various registers. i have done as suggested with SI103 etc that works great, and reconnects after a short period

Hi there, I have to update program on a site where we already have 2x samba 43 in place, I will need to poll some modbus values and show them on the displays from 4 RS485 devices, - VSD and soft starters, these will all be on a RS485 to TCP gateway, in my complete program I have made a separate working example of what i'm trying to do, by using 2 spare sambas i have, as a master & slave combo i just wanted to know if its the best practice way of doing it when polling the 24 to 30 different values needed I am also curious about the settings to do with SB168 Link lost auto recover, do i then need to set some time values in SI 103-110 to make it work properly? Any help or advice is always appreciated! network.vlp network slave.vlp

Hi there, I have an installation with 2 softstarters that use rs485 modbus and an ethernet gateway that is the master of that ring I can send and receive all data needed using Modscan32 over TCP connection on laptop to both softstarters so far i havent been able to get a response from the softstarter when using the PLC - error code 5 and 4. SO I guess the question is, does the slave ID get sent along with the 'message' when using modbus ip function blocks, so the gateway knows where to forward the message?

Thanks for your help, i'll try as you suggest without splash screen and go from there

Sorry its been night time sending file now Thanks

can i email it to you

Hi Saragani At this stage I cant confirm the OS version I will have to travel to site again, I believe it is the newest that came with the visilogic software 9.8.31 as I haven't been prompted for an update, and the PLC is only a month old As for the program I can email it to you apparently I am only allowed to upload .01MB and the file is 1.5MB Thanks Kieran

hi there I was debugging a program on a V700 over a direct connected Ethernet link to the PLC and laptop while debugging eventually visilogic would randomly close with the attached error screen I could easily restart visilogic and reconnect the link to continue debugging so more of an inconvenience than anything any help would be appreciated

Hi there I was using remote operator for a new v700 install When I went to enter a value onscreen the remote operator was using a different keyboard layout to the PLC and so couldn't enter the value correctly Photos attached for reference taken of PLC and remote operator, any insight would be appreciated also I am using the latest Remote Operator 1.0.60.0

Well I don't know what was happening yesterday but today it works perfectly with a 1 min 'keep port closed timer' thanks

Thanks for the reply. I was thinking down the same path so used the TCP close port option, after a delay had been reached using condition of SB148 socket connected status bit, then kept it closed for 30 seconds I could see in the ladder the socket was closed but remote operator was still working. Maybe I need to wait longer for the time out? I have attached the file I was testing with remote operator test file.vlp

Hi I am using this software for a company to keep tabs on a remote PLC we have just had the issue where someone has left there computer connected on remote operator and so no one else can check on it, also used a bit of data, Is it possible to have a maximum connection time either in the Remote program or something I could add at the PLC end? Any ideas would be appreciated Kieran

Built in Com port issue

Thanks for all your replies. I have since installed a replacement v430 that has fixed the issues Modbus up and running with correct values into correct MIs I now have the fun of explaining to the masters that their 2 min scan update time is quite hard to work with.... Clients love using our remote operator though over fiber internet, just like being onsite -

Thanks Yes I have double checked that, and as you say I would get nothing if it wasn't set up correctly
