Chapter 1. Introduction12 PACSystems* RX7i, RX3i and RSTi-EP CPU Reference Manual GFK-2222AD1.5 RSTi-EP OverviewRSTi-EP CPUs make it possible to incorporate the entire PACSystems programming suite in stand-aloneapplications or as auxiliary control in larger process applications that use RX3i. They allow the User toleverage the power and flexibility of PACSystems in smaller applications.At a high level, CPE100/CPE115 supports real-time application status, remote diagnostics and:• Dual LAN interfaces with four Ethernet ports• Built-in RS-232 serial port• Support for a range of communications protocols, including PROFINET• CPE100/115 supports 1 MB /1.5MB of non-volatile user memory.All in just 1.5” (38.1mm) of DIN rail space.CPE100/CPE115 supports two independent 10/100 Ethernet LANs. LAN1 has only one port and isdedicated to highspeed Ethernet and whereas LAN2 is comprised of three switched ports (labelled as 2,3 & 4) configurable as either a second embedded Ethernet controller or an embedded PROFINETcontroller. All four ports are located on the front panel of the CPU.The Ethernet controller Interface of CPE100/CPE115 provides Transmission Control Protocol andInternet Protocol (TCP/IP) communications with other control systems, host computers running the HostCommunications Toolkit or programmer software, and computers running the TCP/IP version of theprogramming software. These communications use the Service Request Transport Protocol (SRTP),Modbus TCP, and Ethernet Global Data (EGD) protocols over a four-layer TCP/IP (Internet) stack.The RSTi-EP CPE100/CPE115 also embeds an industry standard PROFINET controller that allows it toconnect to any type of PROFINET I/O solutions either from GE or any third party. It offers enhancedproductivity, flexibility and performance advantages for virtually any type of control application in a rangeof industries. PROFINET supports a variety of I/O without compromising system performance and canoperate in high-noise environments.The RSTi-EP CPE100/CPE115 is secure by design, incorporating technologies such as Trusted PlatformModules (currently disabled) and verified boot. Centralized configuration allows encrypted firmwareupdates to be executed from a secure central location.
