PACSystems RX7i CPUs are programmed and configured using dedicated programming software to perform real-time control of machines, processes, and material handling systems.

The CPU communicates with I/O and intelligent option modules via a rack-mounted backplane compliant with the VME64 standard. Communication with programming workstations and HMI devices is provided through embedded Ethernet interfaces or a serial port using the SNP Slave protocol.
