Connect Brother CNC-D00 (SPEEDIO)
Brother's CNC-D00 lists OPC UA among its NC functions. Integrator documentation shows the server enabled by communication parameter 0235 "OPC UA server function" = Valid, with security set by 0236 and 0237 (0 = no user or password, 1 to 5 = RSA/AES levels with authentication). Brother does not state whether OPC UA is standard or an option.
At a glance
| Native protocol | OPC UA server (parameter 0235) |
|---|---|
| Other interfaces | Ethernet, USB, RS232C optional |
| Fieldbus | CC-Link, PROFIBUS DP, DeviceNet, PROFINET, EtherNet/IP slave |
| Endpoint | opc.tcp://<ip>:4840 in integrator example |

Data you can read
- Through OPC UA: node list not published
- Through the register protocol: program numbers, operation and power-on times, counters, state, mode, alarms, doors, overrides, G/M-code groups, coordinates up to 8 axes, feed, spindle, tools, logs, PLC devices
Setting it up
- Open the communication parametersDATABANK → 7. Communication parameter.
- Set the network0202 DHCP, 0203 IP address (12 digits, no dots, e.g. 172022003034), 0204 mask; 0004 Display slave command alarm = No; 0216 Restrict Ethernet access = No.
- Enable OPC UA0235 OPC UA server function = Valid; 0236 Security communication for client = 2: Type2; 0237 security level (0 = none, 1–5 = RSA/AES with authentication).
- CheckMONITR → 3. Communication monitor shows "Ethernet (OPC UA)".
Troubleshooting
| Symptom | Likely cause | Fix |
|---|---|---|
| Client cannot log in | Security level and credentials mismatch | Align 0237 with the client policy; level 0 means no authentication, use it only on an isolated network. |
Traps to avoid
- Security level 0 disables authentication.

Questions engineers ask
How do I enable OPC UA on a Brother D00?
Communication parameter 0235 = Valid, then set security in 0236 and 0237, and check the communication monitor.
