Imperious Technology provides OPC I/O servers, test sets, and protocol analyzers, primarily for industrial automation scenarios such as SCADA, RTU/PLC, and HMI/MMI. Its products include Smart Master/Slave I/O Server, Smart Protocol Analyzer, EZ-OPC scripting client, and OPC HTML tools, with a focus on the DNP3, Modbus, and OPC ecosystems.
Smart Master I/O Server supports DNP3, MODBUS RTU, MODBUS ASCII, and MODBUS TCP master protocols, with an emphasis on large-scale systems, low CPU usage, and redundancy. Smart Slave Server can define DNP3 and Modbus slave devices for protocol conversion, data gateways, simulation, testing, and training. Smart Protocol Analyzer can listen to communications over serial, TCP/IP, UDP/IP, and other links, decode industrial protocols into readable content, and simulate both master and slave devices. Its SmartPA SQL is a particularly distinctive feature, allowing users to quickly search large volumes of DNP/Modbus transactions using SQL-like statements based on conditions such as registers, values, status, and timestamps.
EZ-OPC supports VBScript, JScript, VB, and .NET, and provides ActiveX controls and an IDE. Client Toolkit is designed for VB and .NET development. I/O Server is compatible with OPC, DDE, FastDDE, and Suitelink, and can connect to HMI platforms such as WonderWare, Citect, Intellution, Iconics, and Rockwell RSView32. The materials also list integration experience with various field devices, relays, RTUs, and power meters, making it suitable for existing industrial sites.
Pricing is based on perpetual commercial licenses plus optional add-on modules. Smart Serial Analyzer costs $599, while Smart PA Remote Access Server costs $999. Modbus protocol modules are typically $500, DNP 3.0 modules are $1,000, and SmartPA SQL is $1,000. DNP3 Master/Slave servers are priced by device count, ranging from $599 to $6,899; deployments with more than 500 devices require contacting the company. Licensing requires a DONGLE hardware key, and includes 30 days of free support, with extended support available as a percentage of the list price.
Its strengths are deep industrial protocol support and a tightly integrated combination of analyzer, simulation, test set, and OPC server capabilities. It is well suited to power, water, oil and gas, system integrators, and field troubleshooting teams. The downsides are that the product format feels relatively traditional: the documentation mentions Windows 32bit and hardware dongles, while public pages lack modern API documentation, trial downloads, and clear information on release activity.
Information on access from mainland China, payment, and local support is not disclosed, so project-based confirmation with sales is required. Alternatives to evaluate include Kepware KEPServerEX, Matrikon OPC, Ignition, ICONICS, or Wireshark with industrial protocol dissector plugins.
