Overview

Haas CNC control panel. Haas machines connect via MTConnect (Next Generation controls) or Haas Serial/DPRNT (Classic controls), providing real-time production data and machine status.

MachineMetrics connects to Haas machines using two primary methods depending on your control type:

Control Type	Connectivity Method	Port	Hardware Required
Next Generation (2017+)	MTConnect	8082	Ethernet only
Next Generation (2017+)	Haas Serial (MDC)	4001	Ethernet only
Classic Control (pre-2017)	Haas Serial (MDC)	4001	Moxa serial-to-Ethernet converter
Very Old (pre-2001)	Digital I/O	N/A	LabJack I/O module, sensors, wiring

Recommended Approach:

• Next Gen Controls: Use MTConnect (primary) + Haas Serial (secondary) for macro variables
• Classic Controls: Use Haas Serial with Moxa converter
• Pre-2001 Machines: Use Digital I/O (no Setting 143 available)

---

Determining Your Haas Control Type

Use these methods to identify which type of Haas control you have:

Visual Identification

Next Generation Control (2017+):

Haas Next Generation control with modern touchscreen interface. Features graphical menus, network settings, and MTConnect capability.

Classic Control (pre-2017) with MDC:

Haas Classic control with text-based interface. Uses Haas Serial (MDC) over RS-232 with Moxa converter.

Classic Control (showing I/O Settings):

Quick Identification Methods

Method 1: Visual Inspection

• Modern touchscreen with graphical interface = Next Generation Control (2017+)
• Text-based green/blue screen = Classic Control (pre-2017)
• Large touch display with icons = Next Generation Control

Method 2: Check Operator's Manual

• Cover states "Next Generation Control" → Use MTConnect
• No "Next Generation" label → Likely Classic control

Method 3: Check Network Settings

1. Press SETTINGS button
2. Navigate to NETWORK → WIRED CONNECTION
3. Modern network interface with Ethernet settings = Next Gen
4. No network section or basic interface = Classic

Method 4: Check Setting 143 (MACHINE DATA COLLECT)

1. Press SETTINGS button
2. Navigate to I/O or MISCELLANEOUS page
3. Find Setting 143 - MACHINE DATA COLLECT
   • Numerical value (e.g., 4001): Next Gen Control → Can use MTConnect or Ethernet Serial
   • ON/OFF toggle: Classic Control → Use RS-232 Serial with Moxa converter
   • Not present: Very old machine → Use Digital I/O instead

---

Method 1: MTConnect (Next Generation Controls)

Best option for Next Gen Haas machines. Provides comprehensive data with no additional hardware.

Prerequisites

• Haas machine with Next Generation control (2017+)
• Ethernet connection capability
• Network access between machine and Edge device
• MTConnect enabled on machine (usually enabled by default)

Configure Haas Next Gen Control

Step 1: Enable MTConnect

1. Press SETTINGS button

2. Navigate to NETWORK → WIRED CONNECTION

3. Configure network settings:

   • IP Address: Set static IP or note DHCP address

Available MTConnect Data Items

Next Gen Haas machines provide via MTConnect:

• Execution State (execution) - ACTIVE, READY, INTERRUPTED, etc.
• Controller Mode (mode) - AUTO, MANUAL, MDI, JOG, etc.
• Program Name (program)
• Tool Number (tool)
• Spindle Speed (Sspeed)
• Spindle Load (Sload)
• Axis Positions (Xabs, Yabs, Zabs, etc.)
• Feed Rate (Fovr, path_feedrate)
• Part Count (PartCountAct)
• Alarms (message)
• And many more...

---

Method 2: Haas Serial (Classic Controls)

Haas Serial uses the MDC (Machine Data Collection) protocol, also known as DPRNT, to communicate with Haas machines.

When to Use Haas Serial

Classic Controls (pre-2017):

• This is your PRIMARY and ONLY connection method
• Classic controls do not have MTConnect
• Uses RS-232 serial port with Moxa serial-to-Ethernet converter
• Provides execution state, program data, and system variables

Next Gen Controls (2017+):

• Use MTConnect as your PRIMARY connection (see Method 1)
• Only add Haas Serial as SECONDARY if you need specific macro/system variables not available via MTConnect
• Next Gen Haas Serial uses Ethernet directly (no Moxa needed)
• Most customers only need MTConnect for Next Gen machines

⚠️ Important: If you have a Next Gen control, start with MTConnect (Method 1). Only add Haas Serial if MTConnect doesn't provide the specific data you need.

---

Two Physical Connection Types

Connection Type	Control Type	Primary or Secondary	Physical Hardware	Port
RS-232 (via Moxa)	Classic (pre-2017)	Primary - your only option	RS-232 serial cable + Moxa NPort 5110 converter	4001 (on Moxa)
Ethernet Direct	Next Gen (2017+)	Secondary - only for macro/system variables	Ethernet cable only	4001

Both use the same Haas MDC protocol, just different physical connections.

Bold entries indicate commonly used variables for production monitoring.

Note: Variable addresses for older Haas controllers can be found in the "Legacy Variable" column. NGC (Next Generation Control) variables are shown in the first column.

Configure Macro Variables in Adapter

To read macro variables, add a macros section to your Haas Serial adapter configuration:

{
  "adapter": {
    "mdcEnabled": 1
  },
  "macros": {
    "opt-stop": 3033,
    "last-m-code": 4113,
    "part-timer": 3023,
    "spindle-rpm": 3027,
    "coolant-level": 13013,
    "g54-x-offset": 5221,
    "tool-1-life": 5701
  }
}

How to Configure:

1. In MachineMetrics, go to Assets → Machines
2. Select your Haas machine
3. Click on the Haas Serial adapter
4. Add the JSON configuration above in the adapter settings JSON field
5. Customize the macro names and variable numbers as needed
6. Save changes

Macro Configuration Format:

• Key (left side): Data item name that will appear in MachineMetrics (use lowercase with hyphens)
• Value (right side): Haas macro variable number

Common Useful Variables:

{
  "adapter": {
    "mdcEnabled": 1
  },
  "macros": {
    "opt-stop-enabled": 3033,
    "block-delete-enabled": 3032,
    "single-block-enabled": 3030,
    "m30-count": 3901,
    "part-timer-seconds": 3023,
    "last-part-timer-seconds": 3024,
    "current-tool": 3026,
    "spindle-rpm-actual": 3027,
    "power-on-hours": 3020,
    "cycle-start-timer": 3021,
    "feed-timer": 3022,
    "coolant-level-percent": 13013
  }
}

These macro variables will appear as data items in MachineMetrics alongside other machine data.

Tool Life Monitoring Example:

For tracking tool life counters and presets, use the tool life monitoring variables:

{
  "adapter": {
    "mdcEnabled": 1
  },
  "macros": {
    "TLM_1_COUNT": 5701,
    "TLM_1_PRESET": 5601,
    "TLM_2_COUNT": 5702,
    "TLM_2_PRESET": 5602,
    "TLM_3_COUNT": 5703,
    "TLM_3_PRESET": 5603,
    "TLM_4_COUNT": 5704,
    "TLM_4_PRESET": 5604,
    "TLM_5_COUNT": 5705,
    "TLM_5_PRESET": 5605
  }
}

Variable Explanation:

• #5601-#5699: Tool life monitor limit (preset/maximum)
• #5701-#5800: Tool life monitor counter (current usage)

Example:

• TLM_1_COUNT (Macro #5701) = Current count for Tool 1
• TLM_1_PRESET (Macro #5601) = Preset limit for Tool 1

If COUNT = 150 and PRESET = 500:

• Tool 1 is at 30% used (70% remaining)

Note: For detailed tool life monitoring setup and configuration, see the Tool Life Monitoring Guide.

Using Both MTConnect and Serial Together

For Next Gen Haas machines, the recommended setup is to use MTConnect as the primary adapter and Haas Serial as a secondary adapter to access macro variables.

Why Use Both?

• MTConnect provides comprehensive machine data (execution, program, speeds, positions, etc.)
• Haas Serial provides access to macro variables and system variables not exposed via MTConnect
• Combine to get the most complete data set

Setup Process

Step 1: Add MTConnect Adapter (Primary)

1. Go to Assets → Machines
2. Click Add Machine
3. Configure as MTConnect (see Method 1 above)
4. Connect to port 8082
5. Save and verify data collection

Step 2: Add Haas Serial Adapter (Secondary)

1. On the same machine, click Add Secondary Adapter
2. Select adapter type: Haas Serial
3. Enter connection details:
   • Connection address: [MACHINE-IP]:4001 (e.g., 10.26.5.142:4001)
     • Use same machine IP as MTConnect, but port 4001
4. Enable Setting 143 on machine (set to 4001)
5. Add macro variables configuration (JSON)
6. Save adapter

Step 3: Create Transform to Prevent Conflicts

The Haas Serial connection may provide a RunStatus data item that conflicts with MTConnect's execution data item. Use a transform adapter to filter it out.

Create Transform Adapter:

1. On the same machine, click Add Secondary Adapter
2. Select adapter type: Transform
3. Add this configuration:

version: 2

# Do NOT pass all data through automatically (use false to control what passes)
mtconnect-passthrough: false

# Deny the RunStatus from Haas Serial to prevent conflict with MTConnect execution
deny-keys:
  - RunStatus

# Pull data items from parent adapters (MTConnect and Haas Serial)
declare-keys:
  - execution  # From MTConnect (primary execution state)
  - program    # From MTConnect
  - tool       # From MTConnect
  - Sspeed     # From MTConnect (spindle speed)
  - opt-stop-enabled        # From Haas Serial (macro variable)
  - part-timer-seconds      # From Haas Serial (macro variable)
  - spindle-rpm-actual      # From Haas Serial (macro variable)
  - coolant-level-percent   # From Haas Serial (macro variable)

# Output all declared data items
data-items:
  - execution
  - program
  - tool
  - Sspeed
  - opt-stop-enabled
  - part-timer-seconds
  - spindle-rpm-actual
  - coolant-level-percent

Important:

• mtconnect-passthrough: false means only declared keys are passed through
• mtconnect-passthrough: true means all parent data passes through automatically (in addition to declared keys)
• Use false when you want explicit control over which data items are output

4. Save transform adapter

Result:

• MTConnect provides execution state (primary)
• Haas Serial provides macro variables
• RunStatus is blocked to prevent conflicts
• All data flows to MachineMetrics cleanly

Troubleshooting

MTConnect Issues

Problem: Cannot reach MTConnect on port 8082

Solutions:

• Verify machine has Next Gen control
• Check MTConnect is enabled in machine settings
• Verify IP address is correct
• Test from browser: http://[MACHINE-IP]:8082/current
• Check firewall allows port 8082
• Ensure machine and Edge are on same network or routable

Problem: MTConnect shows "UNAVAILABLE" for many data items

Solutions:

• Machine may be powered off or in alarm state
• Wait for machine to fully boot up
• Clear any active alarms on machine
• Cycle power on machine control

Problem: Part count not incrementing

Solutions:

• Check Setting 57 (parts counter reset) on machine
• Verify machine is actually counting parts on screen
• Part counter may need to be configured in machine M-code program
• See Haas manual for part counter setup

---

Haas Serial Issues

Problem: No data from Haas Serial connection

Solutions:

• Next Gen: Verify Setting 143 is set to 4001 (not ON/OFF)
• Classic: Verify Setting 143 is ON
• Check IP address and port 4001 are correct
• Test connection with telnet: telnet [IP] 4001
• Verify serial parameters match (38400, Even, 7, 1)
• Classic only: Check Moxa converter is powered and connected

Problem: Moxa converter not responding (Classic controls)

Solutions:

• Verify Moxa has power (LED should be lit)
• Check Ethernet cable connection to Moxa
• Use Moxa Device Search Utility to find Moxa IP
• Reset Moxa to factory defaults (hold reset button 10 seconds)
• Verify Moxa serial port settings match machine settings

Problem: Data comes through but looks garbled

Solutions:

• Serial parameters mismatch - verify all settings match exactly
• Check cable is not damaged
• Verify baud rate is 38400 on both machine and Moxa/adapter
• Ensure parity is EVEN (not NONE or ODD)
• Verify data bits are 7 (not 8)

Problem: Macro variables show "UNAVAILABLE"

Solutions:

• Check JSON configuration syntax is correct
• Verify macro variable numbers are valid (see reference)
• Some variables are read-only and may show UNAVAILABLE if condition not met
• Test with common variables like #3027 (spindle RPM) to verify connection

---

Connection Conflicts

Problem: Both MTConnect and Haas Serial show execution state but they conflict

Solution:

• Use transform adapter to deny RunStatus from Haas Serial
• Let MTConnect provide execution as primary state
• See "Using Both MTConnect and Serial Together" section above

Problem: Duplicate data items from MTConnect and Serial

Solution:

• Use transform adapter with deny-keys to block duplicates
• Decide which source is authoritative for each data item
• Keep MTConnect data for standard items, Serial only for macros
