What Is the Intelligent Integrated Node (IIN)?

Built around the Moxa ioPAC 6500 Series, the Intelligent Integrated Node (IIN) is a single, unified controller platform engineered for harsh, hazardous, and unmanned industrial sites.

Moving Beyond Fragmented Automation Architectures

Many industrial automation deployments still rely on a patchwork of device brands, standalone gateways, and disconnected configuration software, making routine system management and maintenance needlessly complicated.

The Moxa ioPAC 6500 modular controller cuts through that complexity. Powered by the IINxpress integrated software suite, it consolidates I/O, communication, and control functions onto one rugged industrial platform, shrinking infrastructure footprint and giving system integrators clearer visibility across remote automation sites.

CORE SOFTWARE ENGINE

The Backbone of Unified System Integration

IINxpress is a CODESYS-based, all-in-one engineering platform that brings system management, configuration, firmware updates, programming, protocol services, and diagnostics together into a single unified workspace.

#include <modbus.h> #include <dnp3.h> int init_protocol_stack() { int port_status = open_serial_port("/dev/ttyM0", 115200); if (port_status < 0) return -1; /* Mapping Modbus Address Map Manually */ uint16_t mb_mapping_reg[100]; for(int i=0; i<100; i++) { mb_mapping_reg[i] = read_raw_field_pin(i); if(mb_mapping_reg[i] == ERROR_TIMEOUT) { log_error("Register Mapping Failed at offset %d", i); } } /* DNP3 Outstation Polling Configuration Logic */ dnp3_context_t dnp3_ctx; dnp3_init_outstation(&dnp3_ctx, 20000, "TCP_ONLY"); dnp3_bind_interface(&dnp3_ctx, mb_mapping_reg); return 0; }

Simplify Industrial Protocol Integration

Built-in protocol services take the complexity out of protocol integration. IINxpress minimizes manual coding, freeing engineers to focus on building automation applications instead of writing low-level code.



Streamlined Mass Deployment

The IINxpress Mass Utility applies configuration files and firmware updates across multiple devices at once, streamlining large-scale rollout and ongoing maintenance.

*Mass deployment functionality is scheduled for release in late 2026.
