Product details description：

SEW DFP 21A Digital input module

The DFP 21A Module is a Communication Module that has an RS-232C serial interface and an Ethernet interface (100Base-TX or 10Base-T) mounted in it. Personal computers, HMI devices, and controllers manufactured by other companies can be connected to the DFP 21A Module via the PORT serial interface and 100Base-TX/10Base-T connectors.The Ethernet interface on the DFP 21A supports the Ethernet and CP-218 port types of the Communication Platform. The rest of this chapter describes the appearance, specifications, and switch settings of the DFP 21A Module.

Communication is not possible with remote devices that support only full-duplex communication. Set the remote device to half-duplex 10Base-T or half-duplex 100Base-TX. If the remote device supports auto-negotiation, then the communication type will be selected automatically. The DFP 21A will attempt to connect in the following order: Full-duplex 100Base-TX, half-duplex 100Base-TX, full-duplex 10Base-T, and then half-duplex 10Base-T.
