FANUC FOCAS Ethernet Nodes

Read FANUC CNC controllers directly over FOCAS Ethernet, with no adapter: batch reads with per-address errors, and a one-call machine snapshot.

Operations

Read · Status

Writes

None: read-only

Errors

Per address, never a guessed value

Read FANUC CNC controllers from pipelines over FOCAS Ethernet. Each operation has its own node in the Pipeline Designer: FANUC FOCAS Ethernet Read and FANUC FOCAS Ethernet Status. Their results have the same shape as the FANUC FOCAS (adapter) connector's Read and Status nodes, so expressions written for one work for the other.

For connection setup, the address catalog and per-function fields, see the FANUC FOCAS Ethernet connection guide.

Configuration Quick Reference

Field	What you choose	Details
Parameters	Connection, Function, Function Parameters, Timeout Override	Select the FANUC FOCAS Ethernet connection profile, pick a function, bind parameters with expression support, and optionally override the timeout.
Settings	Description, Timeout (seconds), Retry on Timeout, Retry on Fail, On Error	Node description, maximum execution time, retry behaviour on timeout or failure, and error strategy. All execution settings default to pipeline-level values.

FANUC FOCAS Ethernet Read Node

Read a list of addresses, each with its value or its own error. Runs a fanuc_ethernet.read function.

Node Configuration

Parameter	Type	Required	Description
Connection	Selection	Yes	FANUC FOCAS Ethernet connection profile to use
Function	Selection	Yes	A fanuc_ethernet.read function from the selected connection
Function Parameters	Dynamic	Varies	Auto-populated from the function (addresses). See Read.
Timeout Override	Number (seconds)	No	Override the default function timeout

Output Structure

{
  "result": {
    "values": [
      { "address": "status.run", "value": "EXECUTING", "ts": "2026-11-03T10:00:00.120Z" },
      { "address": "macro.501", "value": null, "ts": "2026-11-03T10:00:00.125Z" },
      { "address": "axis.9.pos.abs", "error": { "code": "INVALID_ADDRESS", "message": "\"axis.9.pos.abs\": the controller has 3 axes" } }

  },
  "_metadata": { "success": true, "functionId": "<function-id>", "durationMs": 14, "timestamp": "2026-11-03T10:00:00Z" }
}

Field	Type	Description
result.values	array	One item per requested address, in order. A read item has address, value and ts (when it was read); value is null for an empty macro variable. A failed item has address and error (code, message) instead.

A read where some addresses fail still succeeds (marked partial); a broken connection fails the node.

FANUC FOCAS Ethernet Status Node

Read the controller identity and a machine snapshot in one call. Runs a fanuc_ethernet.status function.

Node Configuration

Parameter	Type	Required	Description
Connection	Selection	Yes	FANUC FOCAS Ethernet connection profile to use
Function	Selection	Yes	A fanuc_ethernet.status function from the selected connection
Timeout Override	Number (seconds)	No	Override the default function timeout

Output Structure

{
  "result": {
    "cncHost": "192.168.1.50",
    "cnc": { "series": "G431", "version": "0010", "cncType": "31", "mtType": "M", "axisCount": 3, "maxAxis": 32 },
    "snapshot": {
      "run": "EXECUTING", "mode": "MEM", "motion": true, "estop": false, "alarm": false,

  },
  "_metadata": { "success": true, "functionId": "<function-id>", "durationMs": 21, "timestamp": "2026-11-03T10:00:00Z" }
}

Field	Type	Description
result.cncHost	string	The CNC the snapshot came from
result.cnc	object	Controller identity: series, version, cncType, mtType, axisCount, maxAxis. Absent when the controller did not report it (then result.unavailable.cnc says why).
result.snapshot	object	run, mode, motion, estop, alarm; and runningProgram, mainProgram, feedRate, spindleSpeed when the controller answers them
result.unavailable	object	Present only when a snapshot field could not be read: each such field with its error (code, message)

{{ $node["FANUC FOCAS Ethernet Status"].result.snapshot.run }}
