Texas Instruments Launches Advanced Modules To Accelerate Connected Factory Automation

Modern manufacturing floors face persistent challenges with communication fragmentation, where field devices, programmable logic controllers, and robotic cells rely on disparate fieldbus and real-time Ethernet protocols. To address this interoperability barrier, Texas Instruments developed the TICS100MOD system-on-module and the TIOM2212 dual-channel IO-Link master, expanding the industrial communication portfolio to link physical sensors and actuators directly to enterprise-level networks through software-programmable hardware.

Engineering Challenges in Multi-Standard Industrial Communication
Industrial automation environments rarely standardize on a single communication architecture. Regional market demands and machine builder requirements typically force original equipment manufacturers to support multiple real-time Ethernet protocols, including EtherCAT, EtherNet/IP, and Profinet. Historically, machine designers had to develop and qualify distinct physical printed circuit board variants for each protocol, adding design verification cycles, complicating inventory management, and increasing engineering overhead across the digital supply chain.

At the field level, connecting intelligent sensors to higher-level industrial networks poses separate integration hurdles. Bridging point-to-point sensor communication with industrial Ethernet fabrics requires robust electrical protection, physical layer transceivers, and deterministic data handling to maintain predictable process data cycle times without overwhelming host processing resources.

Hardware Architecture of the TICS100MOD System-on-Module
The TICS100MOD system-on-module addresses higher-level networking by integrating the Texas Instruments AM2612 microcontroller and the DP83826AI Ethernet physical layer onto a single miniaturized board. The compute subsystem is powered by two Arm Cortex-R5F real-time processing cores paired with external memory, providing sufficient processing capacity to execute certified protocol stacks alongside local application code in a compact footprint.

A central architectural feature of the module is boot-time protocol switching. System designers can configure the module for EtherCAT, EtherNet/IP, or Profinet through firmware updates rather than hardware redesigns. The underlying microcontroller architecture utilizes a programmable real-time unit and industrial communication subsystem (PRU-ICSS), which executes time-critical industrial communication protocols deterministically. By isolating cyclic bus traffic and frame handling within dedicated real-time hardware, the general-purpose Arm CPU cores remain fully available for control algorithms and process execution.

Field-Level Sensor Bridging via the TIOM2212 Master
To connect the sensor and actuator tier to higher-level controllers, Texas Instruments engineered the TIOM2212 dual-channel IO-Link master. The device integrates analog front-end circuitry and built-in electrical protection to maintain signal integrity during industrial data exchange in electrically noisy production environments.

The master IC incorporates an integrated frame handler designed for direct compatibility with Sitara industrial networking system-on-chip devices and AM13Ex real-time microcontrollers. This hardware-level integration relieves the host processor of low-level IO-Link message framing tasks, cutting development complexity and bill-of-materials costs when aggregating sensor telemetry into the broader automotive data ecosystem and factory automation backbones.

Industrial Applications and Implementation Benefits
The integrated hardware and software approach targets robotics, factory automation lines, and process sensing systems where low latency and determinism are required. SICK, an industrial sensor manufacturer, uses these industrial Ethernet and IO-Link communication platforms in products such as the SIG300 sensor integration gateway to provide connectivity across automated machinery.

Transitioning to a unified hardware architecture offers specific operational advantages:

Protocol Flexibility: Firmware-driven switching allows equipment builders to ship identical hardware across global regions, adjusting communication stacks during device provisioning.

Deterministic Real-Time Performance: Offloading protocol execution to specialized processing blocks guarantees consistent cyclic data exchange, matching the timing requirements of motion control and high-speed inspection.

Direct Media Access Control: Full access to the media access control layer enables custom protocol customization across the stack.

Single-Vendor Hardware and Software Stacks: The module platform is accompanied by an industrial communication software development kit containing pre-certified protocol stacks, evaluation modules, and diagnostic tools to compress development timelines.

Additional Context
This section details technical specifications and competitive benchmarking not included in the original product announcement.

Industrial networking modules typically operate in compliance with IEC 61158 standards for fieldbus systems and IEC 61139 for functional safety protocols, alongside IEC 61131-9 governing single-drop digital communication interfaces for small sensors and actuators (IO-Link). In industrial automation architectures, multi-protocol solutions generally compete with established interface modules and discrete controllers from vendors such as Hilscher (netX series) and HMS Networks (Anybus CompactCom).

While modular communication devices like the Anybus CompactCom offer multi-network switching using dedicated network coprocessors, module implementations centered around programmable real-time units—such as the PRU-ICSS in the AM2612—allow engineers to achieve sub-microsecond internal latency without relying on proprietary external network ASICs. In comparison to discrete multi-chip implementations requiring a standalone microcontroller, external media access controller, and separate PHY transceivers, integrated system-on-modules reduce required PCB surface area by up to 60 percent, reducing thermal management and high-frequency trace routing challenges on compact industrial automation boards.
