Internet PLC Forum

As I noted on my other message on the E-mail server address, I now have working E-mailing through the Trilogi Server on a PC, and DSL that is connected and logged in prior. I would prefer not to have powered up the PC and DSL on a regular basis. The other methods suggested are at least a similar amount of hardware to keep powered up and additional costs. For the somewhat rare that there will be need to send a message as a result of an alarm condition, I was really anticipating only a modem needed, and that power could be controlled by the PLC to be on only when a message was to be sent.

Stop me here if I am wrong. It seems that in the current day situation, about the only way to send and E-mail either dialup or broadband is to logon to the network that uses something more than a basic logon, and PPP, SLIP, or some other protocol is required that the PLC is not capable of. Then dialup E-mail is not available and the examples should be changed.  

Longer term, I would prefer a dialer with text to voice synthesis, but that looks like a lot of development time that I don't have at the moment.

My ISP is Alltel.net or it's successor Windstream.net. I do not use webmail, and all E-mail is downloaded to the PC. I use Thunderbird for E-mail, others use Outlook (express) with no problems. the server info from Thunderbird includes:
pop.alltel.net port 110
mail.alltel.net port 25 for outgoing

There is no security required. I have checked use TLS if available, but can send and receive with "NEVER" checked.

I didn't have to contact the ISP for a mail server address to set up E-mail first. It seems that it's something that I should have here that Windows and Linux handle automatically. Is that Thrilogi server address (above the check times) a number like 10.0.0.2, or  mail.alltel.net

The modem is connected to the PLC via port1 RS-232 and I have no problem getting the modem to dial and establish a connection, but not successful logon to the ISP. The sample program does not provide for a username, but that should not be an issue, once I am able to determine the protocol and log on successfully using a terminal program. The PC that can be connected to the PLC for programming has ability to dialup or DSL, but I would rather not have the PC and DSL powered up while on vacation.

I have a PLC that would like to login in to my ISP and send an E-mail if there is an alarm condition, like high water level of a sump pump. The PLC can be programmed and communicates via RS-232 to a dialup modem on a land line. With the PLC or a terminal software (Realterm) have no problem dialing, connecting and getting the ISP login message ending with "..User name:<sp>", but unable to get verified as a user, even though the username and password are correct. Long conversation with ISP (Windstream, used to be Alltel) India tech support didn't help, they know nothing of the login protocol and format.

Using a RS-232 Spy software (Free Serial Port Monitor) I am able to catch the Windows XP Dialer conversation which is able to logon successfully reliably. Several runs of logging on seems to indicated that the conversation is consistent with exactly the same strings of characters each time, ruling out noise. The following is the conversation after the "..User name:<sp>" and through my username and password being sent out. I have changed my username and password to protect the innocent. The password follows the 07h after the username (E-mail address).

1:Can someone explain what's happening with the conversation between the request and sending the user name?
2: Looks like some kind of encryption or protocol like TCP/IP or? Sending what info?
3: I would rather not program the PLC for all this garbage, is there a work around?

I have Wine installed, but don't have any applications installed yet. Was hoping that Trilogi would run native under Linux. Seems like it's got a chance, just have some bugs. When I get some timein the next day or to, will try Wine both with Trilogi and some other application.

Incidently my experience is goes back to day one of PC's, and 3 years ago got into the PLC as a management for a standby generator that runs gasoline, natural gas, or propane, switches automatically between them under load depending whats available. Do some Basic and C programming, very little assembly. Have designed and built PCBs including the signal conditioning for the PLC. Just a Newbie when it comes to Linux though, and it's been somewhat painful, too many things gon wrong, and takes a lot of research to fix with command line.

Was trying to install, and it;s web install conterpart:
Downloaded 1/19/08 the file jre-6u3-windows-i586-p-s.exe
and then tried

Trilogi disk: j2re-1_4_2_06-windows-i586-p.exe (this one had installed previously on same Windows ME install disk, computer changed from 386 to P4. P4 motherboard previously running XP PRO and Java and Trilogi are OK.

Which all failed.

Per suggestion tried version that I downloaded 11/15/2006 - jre-1_5_0_09-windows-i586-p-s.exe
Java control panel reports version 1.5.0_09-b03. It installed and current version of Trilogi appears to be working fine.

Thanks for the tip.

Can I run Trilogi under Linux (Gutsy Kubuntu). If so, how do I do it? I'm thinking Java is available on both Linux and Windows. Trilogi is installed on an Windows XP Pro machine that is networked to the Linux machine, so access to the Java applications is not an issue. Or can I run it under Wine as a windows application?

This machine is planned to be a backup, put away in a closet, unless the main machine crashes, and hopefully won't ever be needed.

What is the life of the light on the HD-HMI. I'm thinking that 2- years continuous on, is too long, and I need to switch it on and off as needed. Use one of the Function keys to turn on, and a PLC timer to turn it off utilizing one of the output terminals.

Also has anyone done a dimmer using a photo cell and one of DAC's, but I don't have an ADC available, they are all in use.
