Is Your Industrial IoT Gateway Holding Your Factory Back?
Here's what most factories are running — and what they're missing.
EM300 Modular Industrial Edge Controller - Built Around Real Industrial Pain Points
Solving Common Industrial Edge Integration Problem We've Heard.
Tired of adding external I/O modules just to fit one more project?
You start with a few meters and PLCs, then suddenly the project grows into multiple panels, mixed signal types, and extra RS485 devices. Before long, fixed-interface gateways either run out of ports — or leave half the channels sitting unused.
Add I/O Without Rebuilding the Control Cabinet
The modular blade-style architecture allows DI/DO and AI/AO expansion only where needed, making it easier to adapt to changing field requirements without redesigning the entire control cabinet. During maintenance, hot-swappable modules can be replaced in minutes without rewiring. Engineers simply replace the module body while keeping the field wiring terminal in place — significantly reducing downtime and on-site maintenance effort.
Is your MES integration getting harder as more devices are added?
A typical production line often includes Siemens, Mitsubishi, Omron PLCs, and legacy CNC machines, all speaking different industrial protocols, yet many factories still attempt to connect them directly to MES or ERP systems. As the system grows, direct device-to-MES integration quickly becomes difficult to maintain, unstable under load, and expensive to scale due to protocol fragmentation and increasing connection complexity.
Eliminate Protocol Fragmentation
EM300 acts as a local industrial protocol gateway and edge computing node, aggregating heterogeneous PLC and CNC data at the edge before converting it into standardized, structured data streams for upstream MES or ERP systems.
Is your energy system truly coordinated at the site — or just connected to the cloud?
Most energy sites connect Grid, PV, BESS, and EV chargers to separate systems, sending data to the cloud without real-time coordination between assets. As a result, energy flows are not optimized in real time, and peak demand charges continue to accumulate despite full system visibility.
Edge-Based Energy Dispatch and Control
EM300 is a modular industrial edge controller, it connects Grid meters, PV inverters, BESS, and EV chargers via Modbus RTU/TCP, IEC104, and DLT645. When PV output falls short, it triggers BESS discharge on-site. When transformer load approaches the limit, it throttles EV charger input. Dispatch logic runs locally via Node-RED — core control continues even when cloud connectivity is lost..
