PLC coding question
- Thread starter x10
- Start date
if it does work and as long as RAM1 is greater then 500 it will keep sending email for ever.
Do you want it to reset if it goes below 500?
try this
RAM3 for email send only 1 time
start
set ram1 0
set ram2 1
set ram3 0
set var1 0
loop:
add t2 ram2 ram1
tstgt ram1 500
calsub send_em1
goto loop
end
send_em1:
tsteq ram3 0
email em1
set ram3 1
set var1 99
ret

If you can use browser login to the board, email should work and board should be fine. It most likely is the email configuration in the notification screen.
After you configured EMs in the NOTIFICATION screen, did you try to send test emails? If test emails not sending, please try to check your email and network configuration.
On the notification screen, we showed examples how to send email through Yahoo server. If your own email server having sending problem, please try to use Yahoo email server first. Please use your own Yahoo account information, not our example information, since we did not show the real Yahoo user ID and password on the example.

Sorry you feel that way. From emails back and forth, we identified the board is a perfect working board. We also offered you if you send it back, we will send you a new board as replacement.

From his email communication, we learnt that he was running setvar.cgi to VAR1 from a computer, at the mean time, he was trying to set VAR1 to another value in PLC. He insisted that the board is defective, because VAR1's value is not being set by PLC. We asked him to try another VAR, since he is running setvar.cgi on VAR1. He also claimed EM testing was working, but PLC failed send out email based on the example posted here referred to VAR1, he believed that was email hardware failure. We are sorry we could not help him to work, since VAR is a variable in RAM, if two processes trying to set it at the same time to different values, it will not work properly. But we really want him to use the board, once he figures out, I am sure he will like it. This forum provided a good learning environment for everyone to post question and concern, so that we can all learn.

Another board won't fix or change the underlying problem.
If you have multiple things trying to set a variable to conflicting values, one of them will always be wrong. That's not a problem with the board.
Similarly, if the test email sends, but the email isn't sending within your code, the chances are that the problem lies in your code, not the board!
I have multichannel temperature loggers in the field that have been running for several years, sending emails every 30 seconds that have never stopped.
The product works fine. I've got probably close to 50 of these boards in service in different places where people rely on them. I wouldn't if they were flaky!
