The VPC3+C handles the message and address identification, the data security sequences and the protocol processing for PROFIBUS-DP. In addition the acyclic communication and alarm messages, described in DPV1 extension, are supported. Furthermore the slave-to-slave communication Data eXchange Broadcast (DXB) and the Isochronous  Mode (IsoM), described in DPV2 extension, are also provided.

Automatic recognition and support of data transmission rates up to 12 Mbit/s, the integration of the complete PROFIBUS-DP protocol, 4 KByte communication RAM and the configurable processor interface are features to create high-performance PROFIBUS slave applications. The device can be operated with either 3.3V or 5V single supply voltage. For 3.3V operation the inputs are 5V tolerant.

VPC3+C is pin-compatible to VPC3+/3+B or also to industrial standard part SPC3 from SIEMENS. Therefore, VPC3+C can replace them in existing applications without any restrictions or SW-modifications.
