OMRON ITNC-EIS01-DRM – DeviceNet Open Network Controller | CS/CJ Series Platform
Engineering Background
The ITNC-EIS01-DRM is OMRON’s dedicated Open Network Controller designed to bridge Ethernet-based supervisory systems with DeviceNet field-level networks. It operates as a standalone gateway device, eliminating the need for a host PLC CPU while enabling direct I/O data exchange between DeviceNet slaves and upper-level SCADA, MES, or EtherNet/IP systems. This architecture is widely adopted in automotive assembly lines, semiconductor fabs, and process automation facilities where deterministic field-bus communication is critical.
Product Positioning
Targeted at control system engineers who require a compact, DIN-rail-mountable network bridge with robust DeviceNet master functionality, the ITNC-EIS01-DRM reduces panel footprint and wiring complexity compared to traditional PLC-based gateway solutions. It is fully compatible with OMRON’s CX-Integrator configuration software and supports standard EDS file management for rapid node commissioning.

- Semiconductor Fabrication: Cleanroom equipment interlocking where deterministic DeviceNet scan cycles are mandatory.
- Food & Beverage Processing: Hygienic line control integrating distributed I/O blocks without a dedicated PLC CPU in each panel.
- Pharmaceutical Batch Control: FDA 21 CFR Part 11-compliant systems requiring auditable network topology documentation.
- Building Automation: HVAC and access-control integration bridging legacy DeviceNet sensors to modern IP-based BMS platforms.
- Machine Tool & Robotics: Multi-axis servo coordination where the ITNC-EIS01-DRM acts as a network concentrator for DeviceNet-enabled drives.
Engineering Advantages
- CPU-less Gateway Architecture: Eliminates the cost and complexity of a full PLC CPU unit for pure network bridging tasks.
- Dual-Protocol Upper Layer: Simultaneous EtherNet/IP and FINS support allows integration with both OMRON and third-party Ethernet controllers.
- High Node Density: Supports up to 63 DeviceNet slaves per unit, covering large distributed I/O topologies in a single device.
- EDS-Based Configuration: Standard Electronic Data Sheet management via CX-Integrator accelerates commissioning and reduces human error.
- Compact DIN-Rail Form Factor: 35 mm width minimizes control panel real estate while maintaining full industrial-grade performance.
- Wide Temperature Range: 0–55 °C operating range suits demanding factory floor environments without additional cooling.
System Architecture & Signal Flow
The ITNC-EIS01-DRM operates as a DeviceNet Master on the field side and as an EtherNet/IP Adapter or FINS node on the supervisory side. Signal flow is as follows:
- DeviceNet Slaves (sensors, actuators, I/O blocks) → cyclic polled I/O via DeviceNet trunk/drop cable.
- ITNC-EIS01-DRM internal memory maps DeviceNet I/O data into FINS memory areas (CIO, DM).
- Ethernet upper layer exposes this memory to SCADA/MES via EtherNet/IP explicit messaging or FINS/TCP commands.
- Host controller (PC, OMRON PLC, or third-party system) reads/writes I/O data over standard Ethernet without any DeviceNet hardware.
This architecture decouples field-bus timing from supervisory polling intervals, ensuring deterministic DeviceNet scan cycles regardless of Ethernet network load.

Technical FAQ
Q: Can the ITNC-EIS01-DRM replace a CS1W-DRM21 DeviceNet master unit?
A: Functionally yes for pure I/O data exchange, but the ITNC-EIS01-DRM is a standalone controller, not a CS/CJ backplane unit. It connects to the host system via Ethernet rather than the PLC backplane.
Q: What is the maximum cable length for the DeviceNet network?
A: At 125 kbps, the trunk cable can extend up to 500 m. At 500 kbps, the maximum trunk length is 100 m, per DeviceNet specification.
Q: Is CX-Integrator required for initial setup?
A: Yes. CX-Integrator (Ver. 2.0+) is required to configure the DeviceNet scan list, assign node addresses, and map I/O data to FINS memory areas.
Q: Does this unit support explicit messaging to DeviceNet slaves?
A: Yes. In addition to polled I/O, the ITNC-EIS01-DRM supports explicit message commands for parameter read/write operations on DeviceNet devices.
Q: What happens if the Ethernet connection is lost?
A: The DeviceNet master scan continues uninterrupted. The unit maintains the last commanded output states until the Ethernet connection is restored or a watchdog timeout triggers a configurable fail-safe output state.
Q: Is the unit compatible with third-party EtherNet/IP scanners (e.g., Allen-Bradley)?
A: Yes. As a standard EtherNet/IP adapter, the ITNC-EIS01-DRM can be accessed by any EtherNet/IP scanner that supports the standard I/O connection model.
