Supported Industrial Protocols

Estimated reading time: 2 min

iGromi OS and our Edge nodes are vendor-agnostic. We natively support more than 40 industrial protocols at the physical and network layers.

Ethernet-based protocols (TCP/IP)

  • OPC-UA: (client and server). Supports X509 certificates and Basic256Sha256 encryption.
  • Modbus TCP: Polling of Coils, Discrete Inputs, Input Registers and Holding Registers.
  • S7 Communication: S7-300, S7-400, S7-1200 and S7-1500 (requires disabling PUT/GET protection in TIA Portal).
  • EtherNet/IP: Rockwell Automation / Allen-Bradley (MicroLogix, ControlLogix).
  • FINS/TCP: Omron.
  • MTConnect: For CNC machines.

Serial protocols (RS-485 / RS-232)

  • Modbus RTU
  • DF1: Omron legacy.
  • Custom ASCII: Lets you inject Python scripts at the edge to parse industrial scales or inkjet printers (Domino, Videojet).

IT and cloud protocols

  • MQTT / Sparkplug B: iGromi OS's native internal communication protocol.
  • REST API: Webhooks for integrations with SAP, Oracle or Microsoft Dynamics.
  • GraphQL: For bulk extraction of historical data into Business Intelligence tools.

Where to go next

Edge Hardware

Installing Production Sensors

How to wire 24V photoelectric, inductive or limit-switch sensors to the iGromi Bridge digital inputs to count production cycles and compute OEE automatically.

Computer Vision

Deploying iGromi Cam (AI Vision)

Mounting, focal distance and lighting for iGromi Cam to detect defects, colors or overlapping products on a conveyor with YOLO/OpenCV inference at the Edge.

Edge Hardware

Basic iGromi Bridge Installation

Installing the iGromi Bridge in a cabinet: 35 mm DIN rail, 24V DC supply, WiFi or Ethernet link and pairing the gateway with your iGromi OS account.

Interoperability

Connecting the Bridge to PLCs (Siemens, Allen-Bradley)

Read tags from Siemens S7 and Allen-Bradley CompactLogix PLCs with the iGromi Bridge over Ethernet or serial, without stopping the machine or editing the Ladder.

Is this for your plant?

This documentation describes how it is done. If you want to know what your particular installation would need, which equipment can be read today and which cannot, the conversation is shorter than reading the whole wiki.
