Login to SatSCADA here


The SCADALink SAT130 is a M2M  Communications platform with Wireless Connectivity via Cellular, Satellite, & Wi-Fi; Wired Connectivity via Ethernet, RS232, & RS485;  I/O via digital and analog (4-20ma) I/O ports. With a suite of integrated communications features the SAT130 is powerful gateway for fixed and mobile industrial asset monitoring applications.

The SAT130 with integral onboard web server,  Modbus Master and Slave RTU functions applications, and multiple LAN and WAN interfaces serves as a IoT Gateway for remote applications.

SAT130 Cell/Satellite WAN Connectivity

Cellular and Satellite WAN Connectivity allows connectivity worldwide.

SAT140 Cell/Satellite WAN Connectivity

All the great features of the SAT130, now with support for LTE networks.

Device Connectivity

Ethernet, RS232, and RS485 connections allows connections to PLC, RTU, DataLogger and Remote Printers. The SAT130 supports Modbus TCP and Modbus via TCP communications to itself and connected devices from SCADA hosts.



The SAT130 with connection via I/O, Modbus Master and Slave Communications via Serial and Ethernet enables the SAT130 to act as a Modbus Master and Slave RTU.

SAT130 Alarm Callout

SAT130 can be configured to generate callout messages on Alarm Conditions on configured tag points in the SAT130. Alarm Callout Feature of the SAT130 can be utilized to provide Alarm Callout function from a single alarm point connected to integrated SAT130 I/O to multiple Modbus registers polled from RTU/PLC at larger remote facilities.

When an Alarm Callout message is generated, all tag point data is updated along with the tag point that generated the alarm. Callout Messages are sent from SAT130 to the SatSCADA Server where customers can interface from their SCADA Host via the SatSCADA Client using modbus or monitored using the SatSCADA Notifier to generate email or SMS notifications. SAT130 works with SCADALink SatSCADA Server software to provide a complete end-to-end satellite networking solution, allowing SCADA Hosts to reach SAT130 terminals located anywhere in the world.
