Productivity 1000 Series PLC Email and Text

Secure PLC Email messaging is now available in the latest version of the Productivity Programming suite. SMTP or Transport layer security (TLS) email with an attachment and/or latest data log files can be sent. To be able to use this feature you must have installed Productivity programming suite v3.4 or higher and then load the latest firmware to the Productivity CPU. We can set up 4 different accounts in our PLC project. Account templates are already installed for some of the more common email servers.
Productivity 1000 Series PLC Email and Text Communication
We will be sending an email using a Gmail account with authentication. This will also include attached logged data files, error and event files. Our message will also include a switch and register current values when sending our email. We will also discuss how the PLC can send a text (SMS) message. Let’s get started.

Note:
Google is removing “Less Secured Apps” in the mail app. (Gmail) If you are using this to send email from your controller, you must enable 2-step verification. This will then give you the option to generate an “App Password” for your controller or program.

Secure Email Requirements – Productivity Series PLC

Productivity Suite Software – V3.4 or higher
Productivity Firmware 1.2.7.37 or higher
Please see the following post for a review on how to update the firmware.
Productivity 1000 Series PLC Firmware UpdateVideo
We are currently working with the Productivity 1000 but this is also available for the Productivity 2000 and 3000 series of controllers.

The same Productivity Suite software will program the entire PLC series.
See the video below to watch our secure Email instruction in action with our Productivity 1000 PLC.

Hardware Configuration – Productivity Series PLC

Select Hardware Config under the Setup in Applications Tools or use the main menu | Setup | Hardware Config.
Productivity 1000 Series PLC Email and Text Communication
Double click on the CPU unit P1-540.
Select the Ethernet Port on the top tabs under the CPU Module.
Productivity 1000 Series PLC Email and Text Communication
Under the TCP/IP Settings
Use the following:
– IP Address – 192.168.1.16
– Subnet Mask – 255.255.255.0
– Default Gateway – 192.168.1.1
We will also set the DNS (Domain Name Server). If we specify a specific IP address such as 74.125.124.27 we do not need a DNS. However, if we specify aspmx.l.google.com then we need a DNS to look up the specific IP address.
In our example, we will be using the google DNS server address.
Preferred DNS address – 8.8.8.8
Alternate DNS address – 8.8.4.4
If this is not specified then the email server may not be found.
Select OK to close the P1-540 window and return to the hardware configuration window.
Our Ethernet port is now set up on the Productivity 1000 PLC.

Mail Accounts 

Select Mail Accounts on the tab menu of the Hardware Configuration window.
Productivity 1000 Series PLC Email and Text Communication
There are pre-programmed email accounts along the right side under Mail Account. We can program a maximum of 4 email accounts in this tab.
Select Google Account by double-clicking on it on the right.
Productivity 1000 Series PLC Email and Text Communication
Account Name – We will call this by the user name gclshortt@gmail.com
Service Name – smtp.gmail.com – This is the default address for Google mail. Since this is a name we have to set up the DNS listed above.
SMTP Server Response Timeout – We will leave this as the default 10 seconds.
Verify Mail Server Certificate – We will leave this as the Default CA Certificate.
Authentication – User Name – This is the user name for the Gmail account.
User Password – This is the Gmail password for the account.
Productivity 1000 Series PLC Email and Text Communication
This is the completed Gmail Properties window. Select OK to return to the hardware configuration window.
We can also set up a restricted Gmail server account in the PLC.

This is similar to our other PLC email posts with the BRX and Do-More programming.
Here’s is a quick way to send email text messages from the PLCVideo

Productivity 1000 Series PLC Email and Text Communication
We have now set up the Ethernet Port and Mail Accounts. The last part is to program email instruction.

Email Instruction – Productivity Series PLC

We will be modifying the program from the post Productivity 1000 Series PLC Data Logger.
P1000 P2000 P3000 Ladder Logic Sample Programming Code
Productivity 1000 Series PLC Email and Text Communication
Under Task Management we will add a new task called Email. This will be placed under the Run Every Scan section.
Productivity 1000 Series PLC Email and Text Communication
Select Send Email (EMAL) under the Communication in the Instructions.
Productivity 1000 Series PLC Email and Text Communication
Our mail account will be gclshortt@gmail.com that we previously set up. All of the accounts will be shown that are set so we can choose.
We will Use Structure named Email. This will set up a number of variables that we can use in our program.
Our From will be sent to gclshortt@gamil.com
Select Attach Error and Event File – This will send the current error and event file with our email.
Select Attach Log File – This will attach the latest log file recorded.
Destination Email Address – We can send to four different email addresses. In our case, we will only be sending it to gclshortt@gmail.com.
Productivity 1000 Series PLC Email and Text Communication
Here is the completed instruction. Select OK
Productivity 1000 Series PLC Email and Text Communication
We will use Switch 1 to send the email when on. The instruction will only trigger on the leading edge of the input signal. Switch 1 transition from off to on only.
Productivity 1000 Series PLC Email and Text Communication
Email Subject
Looking at the email subject we will set the subject string in our tag database to “ACC Automation Test P1000 Email”
Email Message
Our email message will start with “Productivity 1000 PLC Email”

We will be using the Pack String instruction to add to our email message. We will be adding the status of switch 2 and the value of the Avg Scan Interval to our email message. The first thing that we need to do is create control characters (CRLF) carriage return and line feed. This will allow us to space the information so it can easily be read.
P1000 P2000 P3000 Ladder Logic Sample Programming Code
The copy data instruction is used to copy 0x0d0a into a CRLF integer array. The 0x0d0a represents the ASCII characters for a line feed and carriage return.
We then use copy characters to copy CRLF IntArray into our CRLF string.
P1000 P2000 P3000 Ladder Logic Sample Programming Code
We can now use a Pack String instruction to create our email message.

Email to SMS (Text) message Gateways

Email to SMS Gateways can be used to forward your message in a text format. Here is a website that will show a List of Email to SMS Gateways.
Here are some that we use in Canada: Example: 613-451-0104 on Rogers network = 6134510104@sms.rogers.com
number@txt.bellmobility.ca
number@sms.wirefree.informe.ca
number@sms.fido.ca
number@msg.telus.com
number@sms.lynxmobility.com
number@text.mtsmobility.com
number@mobiletxt.ca
number@pcs.rogers.com
number@sms.sasktel.com
number@vmobile.ca
number@txt.windmobile.ca
number@sms.wirefree.informe.ca

Note:
When using Gmail accounts, sometimes you need to turn on the Less secure app access.
1 – Sign in to Gmail
2 – Click here to access Less Secure App Access in My Account.
3 – Next to “Allow less secure apps: OFF,” select the toggle switch to turn ON.

This setting may not be available for:
Accounts with 2-Step Verification enabled: Such accounts require an application-specific password for less secure apps access.
G Suite users: This setting is hidden if your administrator has locked less secure app account access.

Gmail Failed TLS handshake (-188)’ error

This is caused by an invalid certificate for Gmail. Go to the following thread on the AD forum. Download the gmailX.cer to your project folder. The certificate is valid until 2028.
