Protocol coverage
Modbus, OPC UA, MQTT, BACnet/IP, EtherNet/IP, EtherCAT, PROFINET, IEC104, IEC61850 and SNMP are all available within one product range, so equipment running different standards can be brought into the same upstream system.
I/O combinations
One to three boards are combined from 56 X- and Y-series expansion boards. A single host therefore yields tens of thousands of I/O combinations, and you configure only the number of points you actually need.
Processing at the edge
EdgePLC models with an NPU run vision-inspection and anomaly-detection models on site. Decisions and control happen locally, without a round trip to the cloud.
Official BLIIoT distributor in Korea
ACUSYS handles supply and technical support in Korea.
Configuration review
Send us your equipment list and upstream system, and we work out the protocol configuration first. Model selection comes after that.
Evaluation support
We support evaluation samples and expansion-board combinations before you commit, and review the test results with you.
On-site support
We support commissioning, communication fault analysis and Node-RED application development.
