What is IIN?

Intelligent Integrated Node (IIN), powered by the ioPAC 6500 Series, is a unified controller platform built for demanding, hazardous, and uncrewed remote industrial environments.

From Complex Architectures to Unified Integration

Industrial automation projects often involve multiple device brands, separate gateways, and disconnected configuration tools, making system management and maintenance unnecessarily complex.

The ioPAC 6500 simplifies this architecture. IINxpress integrated services bring I/O, communications, and control together on a single rugged platform, reducing infrastructure complexity and improving visibility across remote automation applications.

CORE SOFTWARE PLATFORM

The Foundation of Unified Integration

IINxpress is an all-in-one, CODESYS-based engineering platform that streamlines system management, configuration, firmware updates, programming, protocol services, and diagnostics from a unified environment.

#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; }
