## What is PLC Tools Plus?

PLC Tools Plus turns your phone or tablet into a portable EtherNet/IP diagnostic tool for compatible PLC controllers. Discover controllers on your local network, explore their full tag database, and watch live values update in real time - all without opening a laptop or launching programming software.

Built for controls engineers, technicians, and integrators who need a fast way to check on a machine from the plant floor.

KEY FEATURES

- Controller Discovery: Scan your local network for EtherNet/IP controllers, or connect directly by IP address. Choose which network interface to scan from when your device has more than one.

- Full Tag Browser: Explore a controller's complete tag database, including nested structures, arrays, and user-defined types (UDTs). Drill down into individual members to find exactly the tag you need.

- Live Data Monitor: Add tags to a live monitoring view grouped by controller, watch values update in real time, and write new values to tags when you need to test or adjust a running process.

- Ethernet/IP IO Scanner: Connect to any IO device that supports Ethernet/IP such field IO and VFDs

- Ethernet/IP IO Device Simulator: Simulate IO devices and connect to it from a PLC. Simulate input data and read output data. 

- Demo PLC Mode: New to the app? Try a simulated "Demo PLC" controller loaded with sample tags, arrays, and UDTs - no real hardware required.

- Built for the Field: A clean, mobile-first interface designed for quick checks on the plant floor, not a scaled-down desktop tool.

REQUIREMENTS

- Your device must be on the same local network as the target PLC(s).
- Compatible with PLC controllers that support the EtherNet/IP (CIP) protocol using symbolic tag names.
