By using an SMS service and SMS channel, you can instruct ClearSCADA to perform actions remotely. This means that engineers and operators can use SMS compatible devices such as mobile telephones to trigger actions in ClearSCADA from any location that has suitable network coverage.
There are three ways of sending an SMS message to trigger an action:
- Use an alias and a Method Call
- Reference the Execute action of a Method Call
