Internet PLC Forum

Thanks for the thorough explaination.  
I am refering the the server running on the TINI computer.  It intercepts the "GET /TLcomm HTTP/1.0" and username/password strings from Trilogi and replies with "HTTP/1.0 200 OK\r\nServer: TLServer/Ver 1.0 Jan 2001\r\nConnection: close\r\n\r\nOK-1\r\n".  It then intercepts the "IR*" request from Trilogi and replies back with "IR01*\r\n".  Trilogi is then happy with the connection and as mentioned earlier all of the other commands work.  All other traffic is passed directly out the RS232 port to the PLC.   I was hoping to get enough detail from you to be able to program my server to work with the 'online monitoring' and 'program download' commands.   If you can help me with that I would be very happy.  Thanks again.

I have dusted off this old project and need some more help.  I followed your advice and now the following commands from the Trilogi Controller menu work:

Select Controller
Connect to Server
Open Matching Source File
Get PLC's Hardware Info
Set PLC's RTC
EEPROM Manager (Read and Write Integer and Strings)

These commands do not work:

Online monitoring
Program Transfer to PLC

A framing error is reported by the PLC and Trilogi requests that I verify that the PLC with the correct ID is connected.

Do these commands require some response from the server before the communication takes place with the PLC?  I have monitored the activity with a packet sniffer but I don't recognize some of the interaction.  If you can offer any advice I would be very grateful.  Thank you for your help.

Thanks for the reply.  I downloaded JAVA version 1.6.0_16 for Vista (32 bit) and the simulator problem has gone away.   I will use this for now and I'll post results after a few weeks.

I have written an ethernet to serial bridge for a Dallas/Maxim TINI microcomputer.  It passes the data directly from the ethernet port to the RS232 port and vice versa once a network connection has been made.  When I try to connect (using Trilogi 6.12 or ExcelLink) ConnectTLServer.commAction() throws an exception because it can't complete the username/password handshaking.  At least I think that is what's happening.   Can you supply me with a Server API or maybe some code examples of how my server needs to reply to the client attempts to log in?

Thanks,

I added an XServer to my system and connected it to a Linksys
WET11 as described in the manual.  It is on my WLAN  at home and accessible from any PC on that network.  I was able to forward its port in my router and can access it from the Internet as well.  I am very impressed with the performance and speed.  It works like a dream.  I highly recommend it to anyone that wants wireless Intranet and/or Internet connectivity to their PLC!  

I have one question for the support group.  The little guy runs pretty hot.  What is the current draw when connected to 24 volts?  It is hot to the touch, especially the ethernet connector housing.  Is that normal?

Thanks for a great product!

I bought a generic one in an eBay auction.  It cost $10 with shipping.  The driver wouldn't work in XP but I was able to download a good driver from the manufacturers website and got it going.  It works fine with my 888 and all other RS232 devices that I've tried it with.
