Firmware Requirements

Minimum Firmware Versions

Before configuring your control for communication with MachineMetrics, the Mitsubishi NCU firmware on the machine must be at or above the minimum version listed in the table below. You must contact your Citizen machine vendor to arrange this update — do not attempt to update the firmware yourself.

The table below shows, for each family, the MINIMUM NC-MAIN version recommended on a control to avoid any compatibility issues:

Model	Minimum Recommended NC-MAIN
A32	AE
K16E	EM
L12	EP
L720	B5
L20E IX	EU
L20X	EM
L220	EQ
L32	EQ
M4xx	EU

⚠️ WARNING: Connecting the machine to MachineMetrics without the minimum recommended NC-MAIN firmware version may cause the machine to alarm.

How to Check Firmware Version

Step 1: Access Software List

Press the MAINT hardkey on the control panel.

Note: Hardkey buttons may vary depending on model of the machine.

Step 2: View Software List

Press the S/W LIST softkey.

Step 3: Verify NC-MAIN Version

Check the NC-MAIN firmware version (firmware P/N) on the screen.

Compare the version shown to the minimum recommended version in the table above.

If the firmware meets the minimum requirements: Proceed to Network Configuration.

If the firmware does NOT meet the minimum requirements, follow this escalation path to get the firmware updated:

1. Contact your Citizen machine vendor first. Reach out to the distributor or dealer who sold or services the machine and request a firmware upgrade to the minimum NC-MAIN version for your model. This is the standard path and should be your first call.

2. If your vendor is unable to help, contact Citizen directly. Many customers have successfully resolved firmware update issues by going directly to Citizen Machinery. This is a well-established path — Citizen has handled these requests before and can coordinate the update even when local vendors cannot.

   • Citizen Machinery Americas: www.citizenmachinery.com
   • Reference your machine model, serial number, and the minimum NC-MAIN version required.

Do Not Contact Mitsubishi

Although Citizen machines use a Mitsubishi NCU, firmware updates for Citizen machines are not supported by Mitsubishi directly. Contacting Mitsubishi will not result in a firmware update for your Citizen machine. Always go through Citizen or your Citizen vendor.

⚠️ WARNING: Connecting the machine to MachineMetrics without the minimum recommended NC-MAIN firmware version may cause the machine to alarm.

Part Counting Methods

Part counting on Citizen machines can use:

1. Work Counter (Preferred)

• Built-in Citizen work counter
• Most accurate method
• Configure in adapter settings

2. M-Code Trigger (M56)

• M56 is the standard Citizen part counter M-code
• Triggers part count increment when executed in the program
• Verify M56 is present in the machine's part program — consult the operator's manual for your specific machine to confirm

3. Barfeeder Signal

• Monitor bar advance signal
• Count on bar stock feed
• Useful for bar-fed operations

Method Selection

Use the following guidance to choose the right part count method:

• Work Counter — Use this as the default for M700-series machines. It is the most reliable method and requires no program changes.
• M-Code Trigger (M56) — Use this when the Work Counter is unavailable or when program-level control is preferred. M56 is the standard Citizen part counter M-code.
• Barfeeder Signal — Use this for bar-fed operations where bar advance is a reliable proxy for part completion.

If you are unsure which method to use, start with Work Counter and switch only if counts are not incrementing correctly.

Machine Setup

Per Citizen documentation, M56 is the part counter. The customer should verify this in their own machine documentation. Once confirmed, M56 is what drives the machine count.

Data Rules

Under data rules, the part counter source should be set to one of the part counters listed in the dropdown.

Configuration in MachineMetrics:

1. Go to Machine Settings → Data Rules
2. Select which part counter source you wish to use from the dropdown

M6 Fallback

If the count value is still not coming through after following the steps above, M6 can be used as a fallback. M6 is triggered during a bar load routine.

Add the following adapter script and map the resulting data item as a part count:

version: 2
declare-keys:
  - block
variables:
  m6-pulse:
    - source: block
    - expression: block == 'M6'
    - rising-edge
  mm-count:
    - source: m6-pulse
    - count
data-items:
  - mm-count

After implementing this script, the mm-count data item must be mapped as a part count. When mapping:

• Give it a name such as MM Count
• Ensure it is selected as a counter under data rules

Citizen M850 Control

Recent Citizen machines ship with the Mitsubishi M850 control. The M850 uses two independent counters:

• Internal HMI counter — the counter the operator sees on the machine screen
• External part-count signal — the signal MachineMetrics reads via the edge device

These counters are independent. If MachineMetrics shows 0 parts while the HMI counter increments, the external signal is not bound to an M-code present in the part program. This binding is configured via parameter #8001.

warning

If parameter #8001 is not set to the M-code used in the part program, MachineMetrics will show 0 parts even though the on-screen HMI counter increments correctly.

Configuring the Part Counter on M850 Controls

1. Press Home
2. Navigate to Parameter → System 1
3. Select Control
4. Select Process Param
5. Set #8001 to the M-code used to count parts in the part program (e.g., 56 for an M56)
6. Power cycle the control

Alternative: I/O Integration

When the native M700 adapter is not available or supplemental signal monitoring is required, Citizen and Miyano machines can be connected using I/O (Digital Input/Output) methods. These use the machine's electrical outputs — stack lights, auxiliary relays, or M-function signals — wired to a MachineMetrics I/O module.

Method 1: Stack Light (Running/In-Cycle Signal)

The most common I/O method taps the green stack light output on the PLC output terminal block.

Locating the output terminals:

Stack light outputs on Citizen machines are typically labeled PATGC / PATG (green — running) and PATRC / PATR (red — alarm) on the CNC8 terminal block inside the electrical cabinet.

Wiring diagram:

Result in MachineMetrics:

The green light voltage signal drops when the machine stops running, enabling automatic cycle time tracking via threshold detection.

---

Method 2: Current Transducer (Spindle Load)

A current transducer (CT) clipped around the spindle drive motor cable provides an analog voltage signal proportional to spindle load — useful for detecting cycle activity on machines without accessible digital outputs.

Result in MachineMetrics:

The CT signal produces a voltage waveform that peaks during cutting and drops to near-zero when idle.

---

Method 3: Bar-Feed Work Count Relay

Citizen machines equipped with bar feeders have a Bar-Feed Work Count Relay (BFWK) in the relay board. This relay pulses each time a new bar feed cycle completes, making it ideal for part counting.

Locating the relay:

The BFWK relay is found on the relay board inside the machine, typically at terminals 24-13 on the relay labeled B2.

---

Method 4: M-Function Relay (Spare M-Code Part Count)

For machines where a dedicated part-count M-code (e.g., M56) is programmed into the NC, the corresponding M-function relay and Mfin signal can be wired to the I/O module as a part-count trigger.

Wiring diagram:

Result in MachineMetrics:

Each M56 pulse is captured as a discrete part-count event.

For full I/O module wiring instructions, see the Digital I/O Connectivity Guide.
