Configured for ControlNet network communication in PC-based industrial control systems, the Allen-Bradley 1784-PCC (1784PCC ControlNet Communication Card) provides direct physical data exchange through a PCMCIA Type II interface.

Model Identification

Hardware Specifications

ControlNet Network Interface Characteristics

The 1784-PCC provides ControlNet communication access from a compatible personal computer platform through a PCMCIA Type II hardware interface. The card transfers network data between the host computer and ControlNet infrastructure through the dedicated communication connector.

The Allen-Bradley ControlNet architecture uses scheduled and unscheduled communication mechanisms for deterministic industrial network data exchange. The 1784-PCC is designed for connection to ControlNet systems requiring PC-based configuration, monitoring, or communication access.

For Allen-Bradley industrial control platforms, firmware and software compatibility must be verified between the communication card revision, host operating system, and ControlNet configuration tools. Network addressing and communication parameters are managed through the connected ControlNet system configuration environment.
