The RX7i CPUs are programmed and configured by the programming software to perform real time control of machines, processes, and material handling systems. The CPU communicates with I/O and smart option modules over a rack-mounted backplane using the VME64 Standard format. It communicates with the programmer and HMI devices via the embedded Ethernet ports or a serial port using SNP Slave protocol. CPE030: 600MHz Pentium-M microprocessor with 64 MB of user memory and 64 MB of user flash CPE040: 1800MHz Pentium-M microprocessor with 64 MB of user memory and 64 MB of user flash Features ▪ Contains 64 Mbytes each of battery-backed user memory and non-volatile flash user memory for user data (program, configuration, register data, and symbolic variable) storage. ▪ Access to bulk memory via reference table %W. ▪ Configurable data and program memory. ▪ Programming in Ladder Diagram, C, Structured Text, and Function Block Diagram. ▪ Auto-located Symbolic Variables that can use any amount of user memory. ▪ Support for Series 90-70 discrete and analog I/O, communications, and other modules. For a list of modules supported, refer to the PACSystems RX7i Installation Manual, GFK-2223. ▪ Support for all VME modules supported by Series 90-70. ▪ Rx7i data monitoring over the web.
