Rite Control PLC

PivotControlPLC gives irrigation operators direct monitoring and control of center-pivot systems from iPhone, iPad, and Mac. Connect to supported Siemens S7 and Allen-Bradley MicroLogix PLCs, view live pivot status, adjust operating settings, and manage multiple pivots from one purpose-built interface.

Monitor heading, speed, pressure, end gun status, barrier positions, water application settings, and runtime state from a clean dashboard designed for field use. The Map view shows multiple pivots at once with live gauge overlays, making it easier to scan farm-wide activity and spot issues quickly.

Pivot configurations are stored securely in iCloud using CloudKit, so your saved pivots and settings can sync across your devices. Built-in sharing lets an owner grant access to other iCloud users, while JSON export and import provide an additional backup path.

Key features:
- Direct PLC communication for supported Siemens and Allen-Bradley controllers
- Live pivot dashboard with heading, speed, pressure, and status gauges
- Multi-pivot Map view with last-known offline snapshots
- CloudKit sync for pivot configurations and settings backups
- Share pivot access with other iCloud users
- Restore saved settings to a PLC after hardware replacement
- JSON export and import for configuration backup
- iPhone, iPad, and Mac Catalyst support

PivotControlPLC is built for agricultural irrigation professionals who need reliable, focused access to pivot controls without a general-purpose HMI layer.
