Engineering Tools Hub

Lightweight, fast, and precise diagnostic utilities built by Valtoris. Designed specifically to help SCADA, IT, and OT professionals troubleshoot industrial networks faster.

Modbus Float Endianness Decoder

Instantly resolve IEEE 754 Endianness mismatches. Decode 32-bit Modbus hex payloads into floating-point decimals across all 4 byte orders simultaneously.

Launch Decoder

Modbus RTU CRC-16 Calculator

Professional debugging tool for Modbus RTU frame verification. Instantly calculate low/high byte checksums and analyze hex dumps without needing external software.

Launch Debugger

Modbus Payload Assembler

Construct complex Function Code 0x10 (Write Multiple Registers) frames with heterogeneous data types and custom CDAB byte swapping parameters.

Launch Assembler

RS485 Reliability Analyzer

Advanced signal integrity analysis based on TIA/EIA-485. Enter your baud rate, distance, and cable specs to instantly check for attenuation limits and signal reflection risks.

Start Analysis

SCADA Polling Collision Predictor

Stop guessing your SCADA timeout settings. Calculate the absolute minimum physical time required for a Modbus transaction to prevent buffer overflows and RS485 bus crashes.

Launch Predictor

Industrial PoE Power Budget Estimator

Calculate IEEE 802.3 voltage drop & exact PSE switch requirements. Prevent thermal failures for PTZ cameras and high-load edge devices.

Start Calculation

Faraday Cage RF Attenuation Evaluator

Calculate signal penetration loss (dBm) through industrial metal control cabinets. Evaluate Faraday cage effects for 4G LTE and Wi-Fi.

Evaluate Signal
In Development

OT Subnet & IP Calculator

Plan your industrial LAN architecture flawlessly. Determine CIDR notations, broadcast addresses, and usable host IP ranges for configuring Edge Routers and PLCs.

Why are these tools free?

At Valtoris, our support engineers use these exact same mathematical models every day to assist customers with complex industrial networking setups. Instead of keeping them internal, we decided to wrap them in a clean interface and give them to the community.

⚠️ ARCHITECTURAL INSIGHT: If your network failures stem from commercial-grade hardware—whether it’s an unmanaged switch dropping PoE cameras under thermal stress, or a transparent dongle causing Modbus collisions—no mathematical calculation will save your architecture. Upgrading to purpose-built Industrial Switches and Edge Gateways is the only permanent fix.
