Siemens Comfort HMI: Send Multiple Emails

[woolie161]

Hi,
I have been successfully sending emails from a Siemens Comfort HMI (TP1200), configured with a "Gmail" address via VB Script.
The VB script was configured to send 2 emails at the same time, with the follow script, called from a TAG change event. and this has been working for about 2 weeks.

Sub VBFunction_1()
On Error Resume Next
If TAG = True Then
SendMail "[email protected]", "Subject", "Email Text", "[email protected]"
SendMail "[email protected]", "Subject", "Email Text", "[email protected]"
End If
End Sub.

If I add 2 more "SendEmail" commands, then no emails are sent!
All email Address are valid and to check spelling etc. the address were copied from my email address book.

Sub VBFunction_1()
On Error Resume Next
If TAG = True Then
SendMail "[email protected]", "Subject", "Email Text", "[email protected]"
SendMail "[email protected]", "Subject", "Email Text", "[email protected]"
SendMail "[email protected]", "Subject", "Email Text", "[email protected]"
SendMail "[email protected]", "Subject", "Email Text", "[email protected]"
End If
End Sub.

My question:
Is there a limit to the number of "SendEmail" commands in the single VB Script?
Is it good coding to send 2 emails, then at the end of that "If-Then" routine, repeat the "If-Then" with the next 2 email address'?
Can someone suggest a good alternative for sending multiple emails?

The Comfort Screen is used in a 24/7 production environment, so I want to limit the number of downloads whilst testing my code.
Thanks
Woolie

Wouldn't it be better to send only one email with multiple addresses in "send to"?

Thanks for replying m_turk,
I had tried separating the different email address' with a semi-colon ( like outlook does, but the Siemens Comfort screen would not accept that format.
It worked when sending 2 emails

Maybe the receiver can be a pool of addresses people rather than single email addresses.
The pool is managed on the receiver rather than by the panel Then you do not have to change the code on the panel if you want to modify the receivers.

Hi All,
Thanks for reading the post. I have solved the issue!
It had nothing to do with the VB Script in the Comfort Screen.
As a coincident, it was a security change by Gmail. They have tightened up the security for 3rd party apps accessing / sending emails.

Email is so much more complicated than it seems like it should be, because there are so many layers of spam protection built into the infrastructure. It's the worst, but also I'm glad it's there, I guess?



I hear horror stories of people who were trying to selfhost their own email server, and all the crazy hoops they had to go through to get other email platforms to accept their mail, for now, until they changed their mind and there are extra hoops.

It's always been like that: a couple of decades ago, I remember someone saying the O'Reilly guide for sendmail was the only one of the series that could stop a bullet.
