Controller

The EPL-P-40 is a Sedona-based application controller and local field I/O platform. It combines physical I/O, control logic, service interfaces, application management and maintenance operations in a single device, and is positioned for projects where the field control algorithm, point engineering and the service lifecycle must live on the same product. SEDONA-BASED CONTROL Sedona is an open control environment in which component-based control applications are built graphically and downloaded to the device. On the EPL-P-40 the application logic is defined through blocks, point links, scheduling, limits, a logic decision tree and service behaviours. The device therefore keeps local I/O and control logic in one place, accepts application changes by reprogramming during a site visit, and runs schedule, alarm, control, math and integration blocks from the same application file. KEY CAPABILITIES • Sedona-based application model • 16 DI, 8 DO, 8 UI, 8 FIO channels • Point-based reading, writing and channel engineering • Configuration and service operations through the local web interface • Field commissioning and quick monitoring over BLE • OTA updates, application package management, backup and restore TYPICAL APPLICATIONS • AHU, pump, boiler and chiller sequence control • Energy management, alarming and status monitoring • Panel applications that require scheduling and field logic • Sensor acquisition and analogue/digital actuator driving • Controller stations commissioned through Niagara, SOX or the local service flow CHANNEL FAMILIES AND POINT MODEL DI — 16 channels: digital monitoring, counter/pulse on the first four (points 1–16) DO — 8 channels: direct or reverse digital output (points 17–24) UI — 8 channels: analogue measurement, digital contact, NTC/PT/NI/resistance sensor input (points 25–32) FIO — 8 channels: analogue output, digital output or digital input (points 33–40) Each point exposes present value, command value, mode, min, max, offset and fault fields.
