Allen-Bradley 1784-PCC is a communication card used for connecting a personal computer (PC) to Allen-Bradley programmable logic controllers (PLCs). It is part of the Allen-Bradley Data Highway Plus (DH+) communication network. The 1784-PCC card allows the PC to communicate with and program the PLCs on the DH+ network.

The 1784-PCC card typically plugs into an available expansion slot on the PC, such as a PCI or ISA slot. It provides the necessary hardware and drivers to establish a communication link between the PC and the DH+ network.

Key features of the 1784-PCC card include:

1. DH+ network connectivity: It connects the PC to the DH+ network, allowing data exchange and remote programming of PLCs.

2. High-speed communication: It supports high-speed data transfer between the PC and the PLCs.

3. Configuration software: It includes configuration software that allows users to set up the communication parameters and establish connections with the PLCs.

4. Compatibility: It is compatible
