Configuration
Here is the Configuration in this tutorial. We are just using TwinCAT3 TF6350 to send an email from our Email account to another email account.
Function Block
I will only explain the Function Block that is used in this tutorial.
FB_SmtpV3
In this Tutorial, FB_SMTPV3 is used.
VAR_INPUT
| sNetId | T_AmsNetID | TwinCAT SMTP Server’s AmsNetID |
| sSmtpServer | T_MaxString | SMTP Server/IP |
| sUsername | T_MaxString | SMTP Server’s UserNameIn this case, it is your user name of the outlook account.e |
| sPassword | T_MaxString | SMTP Server’s PasswordIn this case, it is your password of the outlook account.e |
| nEncryption | UDINT | 0=NONE, 1=STARTTLS, 2=SSL |
| sFrom | T_MaxString | The Sender Email Address,In this case, it is your Outlook address. |
| sTo | T_MaxString | The Receiver Email Address,You need to configure at least one Receiver.. |
| sCc | T_MaxString | The CC Receiver Email Address |

VAR_OUTPUT
| bBusy | BOOL | True=Executing |
| bError | BOOL | True=Function Block Error |
| nErrId | UDINT | Error Information |
Implementation
Now we will start to make a simple program.
VAR
Variables used in our program are defined in the VAR area.
Message is the content of your email.
| PROGRAM MAIN VAR SmtpV3:FB_SmtpV3; Message:STRING; bSend:BOOL; END_VAR |
PROGRAM
Please set the nEncryption=1.It is because STARTTLS is used in the Outlook SMTP Setting.
For the sFrom parameter,you only need to enter your outlook address.and the Function Block will execute while bSend is True.
| Message:=’Hello! this is a test!’; SmtpV3( sSmtpServer:=’smtp.office365.com’ ,sUsername:=’YourOutlookAccount_Username’ ,sPassword:=’YourOutlookAccount_Password’ ,nEncryption:=1 ,sFrom:=’YourOutlook_Email’ ,sTo:=’The receiver’ ,sSubject:=’Test subject’ ,pMessage:=ADR(Message) ,cbMessage:=SIZEOF(Message) ,bExecute:=bSend ); IF bSend AND NOT SmtpV3.bBusy THEN bSend:=FALSE; END_IF |
Result
You can receive the email 🙂
Sample Code
Summary
Finally, when I was looking for information to send to Gmail or Outlook on the Internet, there are so many websites that are roughly similar. But these sites haven’t touched any settings on the Gmail side or the Outlook side. I felt a little irresponsible there. If it’s a memo blog, it’s still good, but if it’s obviously a tutorial-based site, It should be more detailed.
My goal is to make it easy for all readers.
