PLC Connection

Electrical connection

Outputs that are not in use must remain unconnected. Any unused conductors in cable outputs must be properly insulated. Do not bend cables below their minimum permissible radius. Always switch off the system before making electrical connections to the product. Where necessary, use shielded cables to minimize electromagnetic interference (EMI).

M12 8-pin A-coded male connector: V+ (24 V) and V– (GND) provide the power supply. Pins A and B are used for RS485 data exchange. The sensor is connected using an 8-pin A-coded M12 cable. Additional pins are assigned to three switching outputs and the current loop, which are only available on certain sensor variants.

M12 4-pin d-coded female Profinet connector: The pins Tx+ and Tx- are used for transmitting data, while Rx+ and Rx- are used for receiving data.

Allocation of an IP address

To integrate the radar sensor into your network, one of the following options must be used:

1. Direct connection via predefined static IP (Option 1)
   The radar sensor is delivered with the predefined IP address 10.10.42.2 and the subnet mask 255.255.255.0.
   To establish a direct connection, configure the LAN port of the PC or laptop to the same subnet range (No DHCP!).

2. Connection via PLC (Option 2)
   When connected to a PLC, the PLC assigns an IP address to the radar sensor automatically.

Ensure that the selected IP address is unique within the network to avoid conflicts.

Connecting the web interface

Open the web interface by entering the sensor’s default IP address (10.10.42.2) or the IP address assigned by the PLC in a web browser. After completing the configuration, disconnect the laptop and connect the sensor to the PLC, unless it is already connected.

No manual saving required → all parameters are stored automatically. If you want to change sensor settings via the PLC, make sure to set the configuration source to PLC.
