Overview

SCADALink DC100: Data Concentrator

The SCADALink DC100 Data Concentrator is a powerful and easy-to-configure device that can be used for I/O point-to-multipoint telemetry over radio systems such as SMX-900, data concentration or a combination of I/O telemetry and data concentration. It’s I/O bus interface enables connection of up to 8 SCADALink I/O modules and with built-in serial and ethernet ports, it can act as a submaster to a SCADA Host, collecting data from remote sites in a hard-wired system or PLC systems that cannot poll.

The DC100, with ability to communicate via Modbus Protocol via Serial (Modbus RTU) and Ethernet (Modbus TCP, Modbus over TCP) enable communication to via wireline, radio, cellular, satellite, and LAN/WAN makes a SCADA Systems integration tool in Oil and Gas, Pipeline, Water, and Power System Industries.

Modbus Master and Slave

With Ethernet and multiple serial port connectivity, the DC100 supports simultaneous Modbus Master and Modbus Slave functionality.

Standard and Enron Modbus

The DC100 supports both Standard and Enron Modbus protocol.

Flexible Data Format Support

Modbus Data formats supported include bit, packed 16 bit, 32 bit long registers, IEEE floating and Modbus Float format and inferred decimal registers enables the DC100 to interface non compatible devices.
