Device discovery

Start a DCP search (compatible with PROFINET): all devices on the network show up in seconds, with their name, IP address, type and role.

DCPIO-DeviceIO-ControllerIO-Supervisor

Locate in the cabinet

Blink a device's LED to physically find it among the modules.

Station name

Rename a device with a name compliance check, in temporary or permanent memory.

IP address

Change address, mask and gateway with validation before sending, or enable DHCP.

Reachability test

Ping the device: the phone borrows a free address in its subnet for the duration of the test.

Reset

Reset communication (name and IP) or restore factory settings, with confirmation before every sensitive action.

Traffic analysis

Passive listening: protocol breakdown, real-time cyclic flows with their period, alarms, most active talkers.

Automatic diagnostics

Duplicate names or IP addresses, invalid mask, inconsistent subnet, stopped flow, broadcast storm.

CSV export

Share the device list and its issues with the app of your choice.

Problems stand out by themselves

Each device shows its status (online, last answer) and the detected issues, sorted by severity. Light or dark theme following your phone, interface in French and English.

Discovery in 3 steps

1

Plug in the adapter

Connect the USB-to-Ethernet adapter directly to the phone.

2

Plug in the network cable

Connect the adapter to the same physical network as the devices, not through a router.

3

Start the search

Tap "Search for devices". The devices are displayed as a list.

Changing the name or IP address of a device in production can interrupt its communication with the PLC. Arjy DCP is intended for networks you administer or are authorized to work on. The app is provided "as is", without warranty. The publisher cannot be held liable for any damage, production downtime or data loss resulting from its use: you remain solely responsible for the changes you make to your devices.

Compatibility

A Gigabit adapter draws more power than a simple cable: a current-limited USB port or a hub can make it drop out. ASIX and PROFINET are trademarks of their respective owners; Arjy DCP is not affiliated with or endorsed by these companies.
