The TOP Server IEC 60870-5-101 Serial Client OPC Driver provides a communication interface for RTUs, IEDs, controllers, and gateways supporting the IEC 60870-5-101 serial protocol for electrical substation automation and power utility SCADA applications.
Works in conjunction with TOP Server's OPC DA, OPC UA & AVEVA SuiteLink client interfaces to deliver connectivity with HMI, SCADA, MES, and Historian applications. Supports balanced and unbalanced communication modes, spontaneous data transmission (Class 1 and Class 2), general interrogation, time synchronization, and all standard ASDU types.
Proven benefits that help you deploy faster and operate more reliably
Supports both balanced and unbalanced IEC 60870-5-101 communication modes for diverse RTU and IED configurations
All standard ASDU types, spontaneous data, general interrogation, time synchronization, and command execution
Proven in thousands of power utility installations worldwide with extensive error handling for data integrity
Supports Ethernet-encapsulated serial for modern network infrastructure while communicating with legacy serial devices
"Outstanding reliability and performance. This driver has been running flawlessly in our substation automation environment for over a year."
