Riedel hiContact

Driver Maturity

Production

Recommended for normal production use.

Caution

Compatibility Note: This information is a general guide and may be incomplete, may not match a specific project implementation, and is subject to change as supported products and versions evolve. Confirm the exact implementation and requirements for each project with Riedel and the relevant equipment vendor, then validate the required functions end to end in the target environment before deployment.

The integration uses fixed TCP Ports on the hiContact.

Minimum hi Version: v1.1.0

Overview

Riedel hiContact connects physical GPIO signals to hi. By default, the integration creates 16 GPI Ports and 16 GPO Ports.

Information

hiContact Hardware Information in Hardware. Use the current Riedel product datasheet as the authoritative source for physical, electrical, and ordering specifications.

Network Requirements

Connection Model: hi opens both TCP connections; GPIO data flows in both directions across the pair.
Multicast / Unicast: Unicast only.
Bandwidth: GPIO control data only.
IP Version: IPv4.
Firewall: Allow the hi system to connect to the hiContact on TCP Ports 10001 and 10002.

Standards Conformance

Standard	Conformance	Notes
hi GPIO Protocol	GPI/GPO state monitoring and output control	Riedel vendor protocol.

Operator Workflow

Inventory > Nodes: On the Ports tab of the hiContact Node, view the live GPI and GPO state, enable test mode per Port, and force test states on outputs.
Functions > Rules: Use a GPI's active or inactive state as a trigger, and switch a GPO with Set GPO on, Set GPO off, GPO follows the Trigger, or Impulse.

Connection Details

Property	Value
Protocol	hi GPIO Protocol
Transport	TCP
Default Port	`10001` and `10002` on hiContact hi initiates both connections
Authentication	None
Encryption in Transit	None; both connections are plaintext TCP.
Connection Model	Two persistent connections initiated by hi
Required License	hiGlue
Traffic Flow	Bidirectional across the connection pair

Required Configuration

Parameter	Description	Default
Host / IP Address	Hostname or IP address of the hiContact	-
Input Count	Number of GPI Ports created in hi, in the Port Settings group. Set when you create the Node.	16
Output Count	Number of GPO Ports created in hi, in the Port Settings group. Set when you create the Node.	16

The TCP Ports are fixed and not configurable: hi connects to 10001 on hiContact for control/output traffic and to 10002 on hiContact for input/status traffic. Status returns over the second connection; it does not require hiContact to open a connection to a listener on hi.

Device-Side Setup

Follow Riedel hiContact Integration Configuration for the device-side and hi-side configuration steps.

Supported Features

Feature	Access	Exposed Operation and Scope
GPI State Monitoring	Read-only	Receive and display opto-isolated input state changes; the inputs share a common ground.
GPI Active/Inactive Triggers	Read-only input events	Trigger configured hi Rules when an input becomes active or inactive; the integration does not drive the inputs.
GPO Output State	Read/write	Set relay-contact output states and read their reported state.
GPO Actions	Write-only output actions	Set on, off, follow-trigger, or impulse behavior. With GPO follows the Trigger, hi sends the expected state again when the hiContact reports a different one.
Port Testing	Read/write test action	View live state and force test states on outputs on the Ports tab of the Node in Inventory > Nodes.

Device Coverage

The integration creates 16 GPI and 16 GPO Ports by default; both counts are configurable when you create the Node. hi identifies the hiContact Mark 1 (hi-IO1616) and hiContact Mark 3 (hi-IO1616B-PoE) automatically after it connects.

This integration supports the Riedel hiContact range.

Tested With identifies devices that have been tested with hi.

Supported Product Range

Riedel hiContact Mark 1 (hi-IO1616)
Riedel hiContact Mark 3 (hi-IO1616B-PoE)

Known Limitations

GPI and GPO are separate, fixed port types. Port direction cannot be changed at runtime.
Ports are numbered from 1, as GPI 1, GPI 2, and so on, and GPO 1, GPO 2, and so on.
The Impulse action switches the GPO for a fixed 1000 ms, then switches it back. The duration cannot be edited.
If hi receives no status data from the hiContact for more than 2 seconds, it closes both connections and reconnects.

What's Not Supported

Physical wiring, contact-closure electrical commissioning, firmware updates, and hardware diagnostics are outside this integration.
