Starnet HDLC and ESP Gateway
The Nexus StarNET HDLC and ESP Gateway is a custom and flexible solution for the upgrading of multiple legacy StartNET devices.
Data Migration for Legacy Systems
The Nexus StarNet Gateway is a rugged, industrial-grade embedded device that is designed for in-the-field operation and contains no mechanical or moving parts. This device can impersonate multiple StarNET Devices, allowing for flexible upgrade scenarios where whole controllers or multiple legacy StarNET devices are to be replaced using a single gateway.
Effortless and Efficient integration with Nexus Data Suite
The StarNET HDLC or ESP Gateway can be integrated with The Nexus Suite using one of the Ethernet connections and data is made available via a variety of standard industrial data protocols and/or interfaces such as PROFIBUS, PROFINET, and MODBUS TCP/RTU.
This exposes the diagnostic data through multiple interfaces simultaneously, sending alarms and logging data for historical purposes.
