Gentlemen,
Thanks for the help. Greg, IP setup was good. Same subnet. Good pings. MikeS, I was running version 3,7 of NetEdit3. I updated to 3,9,1,8 and got the option to enable the web interface. Also got the option to enable SMTP authentication both through NetEdit3 and the web interface.
I still have my initial problem which is that I can't send e-mails from the PLC. I tried three different SMTP servers with multiple ports and still no joy. With SMTP Viewer Tool I either get
Timeout during SMTP_HELLO_SENT (Error Code 12)
or
Internal error err == 0x0 p = 0x0 (Error Code 23 Invalid Data)
I tried increasing the Timeout to 300 sec. I can send e-mails from computers on my network using any one of the three SMTP servers/accounts. I've read through EMAILTheoryOfOperation.pdf and the online FAQ's but still haven't stumbled on a combination that will work. Any suggestions?
Again, thanks for the help.
