OEE, Modbus, OPC UA, MQTT, PLC data types and network planning: free browser tools, technical articles and printable checklists for manufacturing, automation and IT/OT teams. In Turkish and English.
Free to use. No account needed. Tool data stays in your browser.
Each tool does much more in its full version. Try the core of three here; your values never leave the browser.
OEE is the product of availability, performance and quality. See how a small loss in each one compounds.
A 32-bit IEEE 754 number split across two 16-bit Modbus registers can arrive in four different orders depending on the device. Type a value and see the difference.
Which order a device uses is vendor-specific; check its documentation.
Enter an IPv4 address with CIDR and get the network, broadcast address and usable range instantly.
Start with a file, a shift or a connection. Get useful answers right in your browser.
View all toolsTurn shift data into availability, performance and quality insights.
Inspect CSV data for variation, trends and outliers.
Convert and scale CSV, JSON and Modbus register data.
Check byte order, numeric data types and engineering scales.
Convert pressure, temperature, flow and other process units in batches.
Plan IPv4 subnets, address ranges and available hosts.
Build RTU/TCP requests, inspect bytes and validate CRC checksums.
Generate multi-channel test data with noise, trends and anomalies.
Assess your starting point and build a prioritized action plan.
Estimate data volume from tag count, sampling and retention.
For each goal: a tool, an article and, where it helps, a PDF checklist. Work through them in order.
OEE calculations, shift data and measurable improvement steps.
Practical integration guidance for Modbus, OPC UA and MQTT.
Assess data quality, security and operational readiness.

Each question in the IT/OT readiness worksheet explained: why it matters, what “verified” looks like and which evidence to bring to the kickoff meeting.
· 4 min
How to structure MQTT topics with an ISA-95-style hierarchy, what belongs in the topic versus the payload, how retained messages and last will fit, and which anti-patterns to avoid.
