EPL-P-40
Programmable Controller
Sedona-based application controller. Control logic, field I/O and service interfaces in one device.

A building’s intelligence
begins in the field.
We design the controller, the gateway and the field module, write their firmware and manufacture their boards. The result: automation hardware that integrates vendor-independently and keeps running on its own in the field.

// 01 WHAT WE DO
Hardware, firmware and software under one roof
Where an automation product is split across three suppliers, responsibility is split too. We do all three ourselves — so when the field asks for something, we can change the board, the firmware or the tool.
01
Hardware design
Circuit design, board layout and mechanics: from the DIN-rail body to the terminal arrangement, designed to work inside a panel.
02
Firmware development
Multitasking firmware on an industrial 32-bit platform: watchdogs, fail-safe behaviour, OTA updates and local web services.
03
Engineering tools
EnergyPlus Workbench and our Niagara modules: our own toolset to build, deploy, back up and service the application in the field.
// 02 TECHNOLOGY
The foundations we build on
No closed protocols, no integration locked behind a licence. Our devices speak the industry’s common language.
// 03 SOLUTIONS
The problems we solve
Products matter as part of an application, not on their own. The six field scenarios we meet most often:
ASHRAE / ANSI 135
BACnet Vendor ID 1600
ASHRAE assigned our devices a globally unique vendor identifier. It means EnergyPlus hardware joins any BACnet building management system under its own identity — not as an “unknown device”.
// 04 PRODUCTS
Field hardware
From the controller to the sensor well — the layers an automation panel needs. Technical documents and purchasing are in the online store.
EPL-I/O-40
Remote I/O Module
A field interface with a fixed Modbus and BACnet surface. Integrates without programming.
View ↗EPL-MBC-100
Modbus TCP/RTU Gateway
Protocol conversion and diagnostics for up to 64 slave devices over two independent RS-485 ports.
View ↗EPL-GSM-100
Modbus GSM Gateway
Remote monitoring and control over SMS at sites without a fixed internet connection.
View ↗EPL-BAC-100
BACnet IP Router
Dual-Ethernet BACnet IP router connecting network segments to each other.
View ↗EPL-FCU4 / EPL-FCU4R
Fan-Coil Multiplexer Board
Four fan-coil units from a single thermostat — a direct cut in thermostat and cabling cost.

Where you feel the difference
The register map and BACnet object surface are fixed. A team that learns it once uses the same map at the next site; commissioning time shortens from project to project.
Our gateways track each slave’s response time and success rate separately and keep the latest faults with timestamps. Which device is breaking the line is written on the screen.
Control logic runs on the device through Sedona. If the server, the network or the head-end drops, sequences and schedules keep running locally and fail-safe defaults take over.
Every device has a local web interface and a BLE service. A technician pairs with a phone, tests the channel, changes a setting; updates arrive over OTA.
The team that designs the board, writes the firmware and manufactures it is the same. When a special terminal layout, a different channel structure or project-specific behaviour is needed, your counterpart does not change.
