Common Questions (FAQ)

What does this adapter actually do?

It acts as a bridge. It takes I/O data from old S908 coaxial cable Remote I/O racks and makes it available on a modern Ethernet network (EtherNet/IP or Modbus TCP).

Can I connect multiple 140CRA31908 adapters in one system?

Yes. You can connect them in a daisy-chain loop using the three Ethernet ports for flexible network layout.

What is the difference between the three Ethernet ports?

Typically, one is a service port for programming. The other two form the device network for the daisy-chain data flow. Refer to the manual for port configuration.

From experience, what is a key setup tip for this module?

Ensure the IP address and network parameters are correctly set before connecting the S908 bus. A mismatch here is a common cause of communication failure.

Does the module need special configuration software?

Yes. You will need Schneider Electric’s EcoStruxure Control Expert or similar engineering software to configure the module and map the I/O data.
