FAQ & terminology

RungTrace supports Allen-Bradley ControlLogix and CompactLogix controllers. Both families receive the same core features, including tag discovery, monitoring and writes, trending, Gantt timelines, logic viewing, Tag Trace, and backplane scanning.

No. You can connect directly by entering a PLC IP address or selecting a saved favorite. If RSLinx is installed, RungTrace can optionally use its driver list to discover existing PLC endpoints.

An L5X is a Studio 5000 project export. RungTrace uses it to graphically display ladder logic and Function Block Diagrams, show Structured Text, browse AOIs, cross-reference tags, and build Tag Trace results.

Ladder logic supports live monitoring, bit toggles, and supported value edits. Function Block Diagrams support live monitoring. Structured Text is currently view-only; live Structured Text values are planned for a later release.

Tag Trace finds the logic that writes to a selected tag and follows that chain through routines and Add-On Instructions. It helps isolate the bit preventing a system or sequence from enabling. A traditional cross-reference tool is also included.

No. It is the fastest selectable sample interval. Actual performance depends on tag count, network latency, PLC load, and display workload. A small number of tags on a clean local network can often achieve 50 ms; larger or remote workloads may sample more slowly.

A global Write Enable control allows writes to be disabled while monitoring and diagnosing a system.
