How does it work?

The GRD family of products helps control and supervise any kind of equipment from distance, be it a control system or process system facilitating the implementation of the remote telemetry systems.

The GRD family of products helps control and supervise any kind of equipment from distance, be it a control system or process system facilitating the implementation of the remote telemetry systems. Additionally it includes the possibility to load a text script to perform internal logics.

 MODELS

Internal Logic Programming:

What is a Script? 
A Script is a file with orders that once loaded on to the GRD1300, or GRD3305, is interpreted and executed.
Operations performed by a Script: The Script describes what operations should be executed by the device, for example:

•  Math Operations
•  Binary Logic Operations
•  Date and Time Operations
•  Working with Timers
•  Read Analog variables
•  Records of Variables
•  Digital I/O Read/Write
•  Sending and receiving SMS
•  Interpretation of data from the serial port
