PLC-ANALYZER pro by AUTEM GmbH is a PC-based tool for real-time recording and analysis of PLC signals. It connects to controllers via standard communication interfaces, so you can capture digital and analog variables without adding measurement hardware or changing the PLC program. That makes it ideal for troubleshooting intermittent faults, accelerating commissioning, and documenting system behavior.
The software offers oscilloscope-style and logic-analyzer views, sequence-of-events lists with absolute timestamps, and powerful trigger options (edges, levels, sequences, and combinations) with pre- and post-trigger buffering. You can perform precise timing measurements with cursors and markers, analyze runtimes and delays, detect thresholds and edges, and generate statistics. For long-term observation, PLC-ANALYZER pro supports continuous logging with ring buffers and automated archiving, helping you catch sporadic issues reliably.
Data can be exported to common formats for further processing or reporting, and built-in documentation tools let you annotate signals and produce clear, shareable reports. The software supports a wide range of PLC platforms and fieldbus protocols through native drivers and is designed for safe, read-only access. It scales from single machines to plant-wide monitoring and supports remote acquisition over networks.
In short, PLC-ANALYZER pro gives engineers and technicians a non-invasive, cycle-precise way to visualize, analyze, and document PLC behavior—reducing downtime, speeding root-cause analysis, and improving process quality. more
