Getting help with EtherNet/IP Explorer
Frequently Asked Questions
I can't connect to my EtherNet/IP device.
Check that the device IP address and port are correct (default EtherNet/IP port is 44818 for TCP, 2222 for UDP). Ensure your Mac and the device are on the same network. If using a VPN or firewall, verify that these ports are not blocked. Try pinging the device IP from Terminal: ping 192.168.1.100
Device discovery doesn't find my device.
Make sure your device is powered on and connected to the same network. Some devices do not respond to broadcast discovery — try entering the IP address manually. Check that the device supports EtherNet/IP (CIP) and not just plain Ethernet.
My license key doesn't work.
Make sure you enter the full key including dashes (format: XXXX-XXXX-XXXX-XXXX). Check that you have an internet connection during first activation — the app needs to validate the key once. After activation, the app works offline. If you still have trouble, contact support below.
How do I read CIP attributes?
Connect to your device, then use the CIP Tag Browser to navigate to the desired class and instance. Select the attribute you want to read and click "Read". For explicit messaging, specify the class, instance, and attribute IDs directly.
How do I establish an implicit (I/O) connection?
Use the Connection Manager to set up a Forward Open request. Configure the T->O (Target to Originator) and O->T (Originator to Target) connection parameters, including assembly instance IDs and data sizes. Click "Forward Open" to establish the connection.
I bought from the Mac App Store. Do I need a license key?
No. The Mac App Store version is automatically licensed through your Apple ID. No license key needed. The paywall only appears in the direct-download (DMG) version.
I bought via Polar.sh but want to switch to the Mac App Store.
Purchases through Polar.sh and the Mac App Store are separate. We cannot transfer purchases between platforms. Both versions are identical in features.
The app crashes or freezes.
Make sure you're running macOS 13 (Ventura) or later. If the app freezes during a CIP operation, try disconnecting and reconnecting. If the issue persists, contact support with your macOS version, the app version, and what you were doing when it happened.
