PLCscopePortable Allen‑Bradley PLC tag monitor
Plug in. Browse tags. Solve problems.
The portable toolkit for instant, safe PLC diagnostics—no laptop or Studio 5000 required. Preorders now open for the first production run.
Faster troubleshooting. Zero laptop. Total control.
PLCscope gives controls engineers and technicians instant visibility into Rockwell PLCs—browse tags, monitor live data, and log or export from a single handheld device. Designed for the field, built for safety.
Native Rockwell Connectivity
Connects directly to Allen‑Bradley / Rockwell Logix PLCs over Ethernet for fast, reliable communication—no laptop required.
Tag Browser & Live Data Table
Automatically discovers controller‑ and program‑scoped tags. View real‑time values, quality, and timestamps in a clean, sortable table.
Safe Writes & Logging
Adjust setpoints and booleans with confirmation, or use read‑only mode for safety. Capture snapshots or trends, export to CSV/JSON, and transfer via USB.
Built for the field. Ready for the future.
For controls engineers, maintenance teams, OEMs, and training labs. Think of it as the Fluke meter for Rockwell PLCs—simple, safe, portable, and ready for the field.
Profiles for Every Machine
Save and reload tag sets for different PLCs, machines, or projects. Instantly switch between jobs in the field.
On-Device Networking
Configure static IP or DHCP directly from the touchscreen. Always know where you’re connected—no laptop or IT needed.
Portable & Rugged
Runs on Seeed reTerminal (Raspberry Pi CM4, 5″ touchscreen), with optional battery pack for true field use.
Safe by Default
Read-only mode is default for safety. All writes require confirmation, so you never risk an accidental change.
Logging & Export
Capture snapshots or continuous trends, export to CSV/JSON, and transfer via USB for easy reporting.
Protocols (Roadmap)
Modbus TCP, Siemens S7, OPC UA, and BACnet/IP on the roadmap—broadening interoperability while keeping setup simple.
How to use
Three quick steps. Under a minute to first data.
Supported Devices
PLCscope communicates over Ethernet only. Serial, DH+, and other legacy fieldbuses are not supported.
