Industrial I/O. Standard SNMP. — Bridge your OT field devices to your IT network management system.
Your IT department manages everything through SNMP — servers, switches, routers, printers. But your field devices — sensors, meters, actuators — speak Modbus. Getting OT data into your IT network management system usually means custom scripts, proprietary gateways, or unsupported hacks.
The BL193 solves this problem. It is an SNMP edge controller that collects Modbus data from your field devices and exposes it as standard SNMP OIDs. Your existing network management system queries the BL193 like any other SNMP device. No custom development. No unsupported workarounds.
Think of it as your OT-to-SNMP bridge — IT‑friendly, industrial‑grade, and ready to deploy.
The BL193 is a standard SNMP agent. Supports SNMP v1, v2c, and v3 with encrypted communication. Built‑in standard MIB libraries. Your existing NMS (Nagios, SolarWinds, PRTG, Zabbix, or any SNMP manager) discovers the BL193 and reads OIDs like any other network device. No special plugins. No custom drivers.
Collect data via Modbus RTU (RS485) or Modbus TCP. The BL193 automatically maps Modbus registers to SNMP OIDs. Your NMS sees clean, structured data. No scripting. No complex mappings. Just configure and go.
Choose 1, 2, or 3 Y Series I/O boards. Local I/O data is also exposed as SNMP OIDs alongside your Modbus device data. Digital, analog, temperature, pulse — all available through SNMP.
Enterprise‑grade security. SNMP v3 supports authentication and privacy (encryption). User policy management. Complies with corporate network security policies. Your IT security team will approve.
Two RJ45 ports with built‑in switch support line topology. Daisy‑chain multiple BL193 controllers without an external switch. Less hardware. Simpler cabling.
Wide‑temperature operation, electrical isolation, EMC/EMI protection, independent hardware watchdog. The BL193 survives in data center hot aisles, outdoor cabinets, and industrial control panels.
Remote firmware upgrades and parameter configuration are built in. Update devices in the field without sending a technician. Reduce downtime. Lower service costs.
Monitor temperature, humidity, power consumption, and access door status in your data center or server room. Existing Modbus sensors connect to BL193 via RS485. BL193 exposes data as SNMP OIDs to your data center NMS. Get alerts when temperature rises or doors open — through your existing IT monitoring system.
Remote base stations need environmental monitoring — temperature, humidity, power status, generator fuel level, door contacts. BL193 collects data from Modbus sensors and reports via SNMP to your central NMS. Wide temperature range ensures reliable operation in outdoor cabinets.
Your IT team manages the industrial network alongside the corporate network. They want SNMP from every device. BL193 gives you SNMP from your field I/O — conveyor status, tank levels, pump running states, alarm conditions. One monitoring system for everything.
Monitor HVAC status, lighting control, energy consumption, and security contacts across a campus. Existing Modbus devices connect to BL193. Facility IT team monitors everything through their existing SNMP-based NMS.
Your customers require SNMP monitoring for your equipment. Your machine uses Modbus internally. Add a BL193 to each machine — it collects internal Modbus data and exposes it via SNMP. Your customers get the monitoring they need. You keep your existing control architecture.
| Version | Security | Best For |
|---|---|---|
| SNMP v1 | Basic community string, no encryption | Legacy systems, internal trusted networks |
| SNMP v2c | Community string, GET/SET support | Most modern NMS, better performance than v1 |
| SNMP v3 | Authentication + encryption (AES-256), user policies | Enterprise networks, security‑conscious IT departments |
