Which communication protocols are supported (TCP, Modbus, REST)?

We support both shop-floor and IT-level integration. Shop floor: custom TCP socket messages, Modbus TCP (configurable master or slave), discrete I/O handshaking and serial ports (RS232/RS485). System level: RESTful APIs with JSON, direct database access, shared-folder file exchange (CSV/XML) and WebSocket real-time push. If your line uses fieldbuses such as OPC UA or PROFINET, these can be connected through a gateway or middleware, and we provide interface documentation to assist. All interfaces are configuration-driven, so no separate software build is needed per protocol.
