From 4eed5d268793641f3623fa94b703d11d7d734cc9 Mon Sep 17 00:00:00 2001 From: Miguel Date: Thu, 28 Aug 2025 13:31:11 +0200 Subject: [PATCH] feat: Add CPU status retrieval and display in dashboard - Implemented `get_cpu_status` method in PLCClient to fetch current CPU state, cycle time, and additional CPU info. - Created a new API endpoint `/api/plc/status` to serve CPU status data. - Updated frontend to load and display CPU status in the Dashboard, including state and cycle time. - Added error handling for CPU status retrieval in the frontend. --- application_events.json | 2364
