Preliminary remarks:
The Ethernet‑based measurement and monitoring systems from the 100 / 500 / 500 DC model series and the PDUs can be equipped with a GSM modem or an LTE modem. To create a notification or alarm message via SMS, the following parameters must be specified in the corresponding menu:
| Parameter: | Description: | |
| Message: | Text of the SMS message | |
| Name: | Name / label of the element | |
| Phone number: | Phone number of the recipient (+4925019785880), up to 10 numbers For multiple phone numbers, separate them with a space, “;”, or “,” Example 1: +4925019785880 +4925019785881 +4925019785883 Example 2: +4925019785880,+4925019785881,+4925019785883 Example 3: +4925019785880;+4925019785881;+4925019785883 |
Important note from the editorial team:

Sending SMS messages via SMS Gate
If several Didactum monitoring systems are in the same network and at least one of them is equipped with an internal GSM modem / LTE modem, you can send SMS messages from Didactum monitoring systems that are not equipped with a modem.
To create an SMS dispatch via SMS Gate, you must specify the following parameters:
| Parameter: | Description: | |
| IP Address | IP address of the Didactum monitoring system with GSM modem | |
| Login | User login of the Didactum monitoring system with GSM modem | |

Important note from the editorial team: The user account on the monitoring system including the GSM modem must have the corresponding rights!
Sending SMS messages via an internet service (Web-to-SMS)
If the monitoring system has internet access, you can optionally send SMS messages via external services. The monitoring unit sends a request to such an (external) service, which in turn sends an SMS to the recipients depending on the API in the request.
You will find the required settings on the website of the Web‑to‑SMS service provider. Didactum supports a generic access mechanism suitable for most Web‑to‑SMS services.
To create a notification via “Web‑to‑SMS”, you must specify the following parameters:
| Parameter: | Description: | |
| Phone number: | Recipient phone number prepared according to the documentation of the Web‑to‑SMS service. | |
| Password: | Password for logging in to the Web‑to‑SMS service. | |
| Name: | Name of the element (e.g. Web to SMS service provider). | |
| Message: | Content of the message. | |
| Login: | User login to the Web‑to‑SMS service. | |
| API string: | API command line compiled according to the documentation of the Web‑to‑SMS service. |
The following macros can be used in the command line:
- $LOGIN$ – User login (field Login);
- $PASSWORD$ – User password in plain text (field Password);
- $PASSWORD_MD5$ – User password as MD5 hash;
- $PASSWORD_SHA1$ – User password as SHA‑1 hash;
- $PHONES$ – Recipient phone numbers (field Phone number);
- $MESSAGE$ – Message text (field Message text).
When creating the command, these macros are replaced with the corresponding values from the form fields and correctly encoded for sending the HTTP request. Parameters specified directly in the command must always be presented in encoded form (URL‑encoded).
