Titan – AN10: Sending SMSs, Emails, SNMP Traps from a Modbus-TCP Device

Looking for something else?

Introduction

The Titan routers include all the typical features of a 2G/3G/4G router. However, they also include a series of additional features that help make it one of the leading market routers based on the number of features it includes.

One of these additional features is the ability to execute AT commands via Modbus TCP. In other words, it is possible to configure the Titan router as a Modbus TCP Slave device, meaning that from a device configured to be a Modbus TCP Master, we can send AT commands via Modbus TCP. In this way, from the Modbus TCP Master device, we can read and receive SMS messages, send emails, send SNMP TRAPS, find out the current time/date, GSM network coverage, etc. All of this using the Titan router.

Description of the Example

We have a Modbus TCP Master device (PLC). We need to be able to send/receive SMS messages, and send SNMP TRAPS via Modbus TCP.

(Image: Sending/Receiving SMS messages; MODBUS TCP device (IP) with an Ethernet port)

Configuring the Modbus TCP Slave

The first thing to be done is to configure the Titan device so that is acts as a Modbus TCP Slave. To do this, we must go to the menu “Other > Modbus TCP Slave”, where we must select the option “Enabled” as well as the TCP port (which is, by default, TCP 502).

It is interesting to see the lower part of the screen where a summary of the Modbus TCP registers mapping is included.

Once the router is configured, we must reset the device so that the new configuration becomes active.

Sending SMS Messages via Modbus TCP

Now we must send an SMS message. As previously mentioned, this is possible from any device or Modbus TCP Master simulator.

We are going to send an SMS with the text “ALARMA” to the cell phone number 681319891. The AT command to send an SMS from the Titan router is as follows:

AT^MTXTUNNEL=SMS,681319891,ALARMA

In ASCII code, this would be:

100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115
A T ^ M T X T U N N E L = S M S
65 84 94 77 84 88 84 85 78 78 69 76 61 83 77 83
116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131
, 6 8 1 3 1 9 8 9 1 , A L A R M
44 54 56 49 51 49 57 56 57 49 44 65 76 65 82 77
132
A
65

Therefore, we will write this command (all 33 characters) in the Titan router from register 100 (inclusive). This is the “memory” where the AT command is stored ready for execution.

Once completed, we must execute the AT command. To do this, we must write in register 98 a value that is equal to the length of the AT command – in this case 33.

Once register 98 includes this value, the AT command will be executed and the SMS should be received seconds later. To check the response to the AT command, we can read register 99, which includes the length of the response. In this case, we read a value of 21. This means that we must read 21 registers from the position 500, which is where the response is stored. Reading, we see the following:

500 501 502 503 504 505 506 507 508 509
[Cr] [Lf] [Cr] [Lf] + C M G S :
13 10 13 10 43 67 77 71 83 58
510 511 512 513 514 515 516 517 518 519 520
9 4 [Cr] [Lf] [Cr] [Lf] O K [Cr] [Lf]
32 57 52 13 10 13 10 79 75 13 10

Here we must check for “OK” in order to check that the AT command was correctly executed.

Receiving SMS Messages via Modbus TCP

Receiving SMS messages via Modbus TCP is also a simple process. In this case the PLC that acts as a Modbus TCP Master must periodically carry out a polling process in register 1000. If this register contains a value of “1”, this indicates that there is an SMS waiting to be read.

The next step is to read register 1001, which indicates the length of the cell phone number that has sent the SMS. Usually, this will be contained from registers 1002 to 1019.

To read the body text, we must read register 1020, which contains the length of the message. The message will be located in registers 1021 to 1180.

Once the SMS is read, we must write a value of “0” in register 1000 so that if the register has a value of “1” in the future, we know that this is due to an unread message.

Sending a TRAP via Modbus TCP

The procedure for sending an SNMP TRAP is exactly the same as for sending SMS messages, except for the AT command. Instead of sending a command like the following:

AT^MTXTUNNEL=SMS,681319891,ALARMA

We would have execute a command as we did before (transforming it into ASCII code), but adapted, as follows:

AT^MTXTUNNEL=TRAP,.1.3.6.1.4.1.45711.1.1.11.1.1;myMessage;5

In other words, we must specify the OID (in this example “.1.3.6.1.4.1.45711.1.1.11.1.1”), as well as a field for the message of the text and another field for the severity (in this case, “5”).

100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115
A T ^ M T X T U N N E L = T R A
65 84 94 77 84 88 84 85 78 78 69 76 61 84 82 65
116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131
P , . 1 . 3 . 6 . 1 . 4 . 1 . 4
80 44 46 49 46 51 46 54 46 49 46 52 46 49 46 52
132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147

m y M e s s a g e ; 5
109 121 77 101 115 115 97 103 101 59 53

The response to the command is completed in the same way as for the SMS explained in this Application Note. Upon seeing the text “OK”, we can confirm that the command was correctly executed.

To which IP address is the TRAP sent? 
The TRAP is sent to the IP address:port which is specified in the configuration menu “External Devices > Modbus RTU/TCP”.

Sending an Email via Modbus TCP

The procedure for sending emails is exactly the same as for SMS or TRAPS, substituting the AT command for the following:

AT^MTXTUNNEL=EMAIL,jgallego@matrix.es,ALARMA

The current Firmware version of the Titan device (v3.07) only allows for emails to be sent by specifying the recipient’s email address and the subject of the email.

Remember that before sending any message, the Titan router must be configured with the appropriate parameters for the SMTP servers to be used, using the menu “Other > Email Configuration”.

CONFIGURATION OF THE WEBDYNRF GATEWAY

  • If the file is deleted from the directory after connecting the WebdynRF gateway, the problem is usually due to a file format error. The configuration and control files must follow the format described in the schema (XSD) files. To check schema consistency, open the XML file with the Notepad++ text editor and install the “XML Tool” add-on. Next, copy the corresponding XSD file to the XML file in the same directory, and select “Validate now” in XML Tool. Errors detected by the tool should be displayed.
  • If the file is not deleted from the server, the most common problem is that the file has not been located correctly. The file must be available on the server in the “INBOX” directory and in the sub-directory bearing the product UID name (e.g.: “/INBOX/0045CE/”).

GENERAL USE OF THE WEBDYNRF GATEWAY

The amount of data exchanged on the GPRS network varies depending on the configuration. However, the average consumption would be about 5MB / month.
The WebdynRF gateway consumes an average of about 250mA.

There are 2 firmware updating methods:
Local updating:
On the WebdynRF configuration interface, go to the “Actions” tab and select the updater in the “File upload” menu before clicking on the “Upload” button

Remote updating:
Upload the file containing the updater (file with extension “.bz2”) in the “BIN” directory to the FTP server . Next, place the update command in the INBOX directory corresponding to your gateway (“INBOX/”, with, the identifier of the gateway concerned)

The update command must follow the following format:

      updater.tar.bz2
      checksum_md5

updater.tar.bz2
checksum_md5

With:

  • updater.tar.bz2: Updater file name uploaded to the “BIN” directory
  • checksum_md5: Md5 code of the updater file

A lack of connection to the FTP server may be due to a network connection problem (Ethernet or GPRS), an FTP login problem or a failure to initiate the connection.

If you cannot connect to the network, check the following points:

  • Ethernet:
    • Modem set to “off” or “always off”
    • “Gateway” fields correctly entered
    • At least one DNS server must be configured
  • GPRS:
    • Modem set to “on”
    • APN, APN ID and APN password correctly entered
    • GPRS call number set to “*99***1#”

If you cannot log in, check the following points:

  • Incorrect FTP parameters
  • TCP port 21 closed at output
  • Domain name resolution problem: the DNS server is not specified

If the connection fails to initiate:

In this case, only the automatic connection does not work. The problem is probably caused by an incorrect schedule configuration. Please note, the schedule ID must be an integer.

 PARTICULAR APPLICATION OF THE WEBDYNRF WIRELESS M-BUS GATEWAY

For the WM-bus module data to be transmitted, you must:

  • Choose the mode corresponding to the modules used (S, T or N)
  • Define the modules or groups of modules to be processed

A module may be defined in a unique way by all the fields below:

  • Id
  • Manufacturer
  • Version
  • Medium

If a module’s data is encrypted, the encryption key for this module can be defined in the “Key” field.

To simplify the entry of the modules to be processed, a module group can be defined that conforms to the fields entered. The other fields will then be left empty (below is an example of a configuration for retrieving all Webdyn manufacturer (WDN) modules with the encryption key “00000000000000000000000000000000”.

  •   Id :
  •   Manufacturer : WDN
