HD67166-A1 Industrial Modbus TCP master to SNMP agent converter – DIN, Type A housing

Industrial Modbus TCP master to SNMP agent converter, housing type A (slim), DIN rail mount.

The HD67166-A1 enables seamless communication between Modbus TCP Slave devices and an SNMP Manager network (such as a PC or supervisory system). This makes it possible to remotely monitor and control Modbus-compatible industrial equipment using SNMP-based network tools. The gateway acts as a real-time translator, ensuring minimal latency and reliable bidirectional data flow, which is essential for industrial automation and SCADA systems.

The device is particularly useful in mixed-protocol environments where legacy Modbus systems need to be integrated with modern network management solutions based on SNMP. It supports automatic Ethernet speed detection (10/100 Mbps) for flexible integration into various infrastructure setups. Thanks to its slim Type A housing (only 23 mm wide), it fits easily into compact electrical cabinets or control panels, making it ideal for both new installations and retrofit projects.

The converter is easily configurable using the free SW67166 software, which offers an intuitive graphical interface for setting up Modbus register mappings and SNMP OIDs. Its wide operating temperature range from -40°C to +85°C makes it suitable for harsh industrial environments, including outdoor control cabinets, substations, and manufacturing plants. The isolated power-to-Ethernet interface helps protect connected systems from voltage spikes and ensures high operational reliability in electromagnetically noisy environments.

Configuration:

Thanks to the SW67166 software on your PC you can:

• Define the parameters of SNMP line (version, IP, community strings)
• Define the parameters of Modbus TCP line (IP, port, timeout, retries)
• Define the Modbus variables to read/write from/to the Modbus slaves, including data types and addresses
• Define the SNMP OIDs and assign them to Modbus registers
• Create and export a MIB file compatible with standard SNMP management software
• Update the device firmware and configuration remotely via Ethernet

The software also includes a test mode for simulating communication and validating the configuration before deployment.
