RSTi-EP Overview
RSTi-EP CPUs make it possible to incorporate the entire PACSystems programming suite in stand-alone
applications or as auxiliary control in larger process applications that use RX3i. They allow the User to
leverage 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 is
dedicated 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 PROFINET
controller. All four ports are located on the front panel of the CPU.
The Ethernet controller Interface of CPE100/CPE115 provides Transmission Control Protocol and
Internet Protocol (TCP/IP) communications with other control systems, host computers running the Host
Communications Toolkit or programmer software, and computers running the TCP/IP version of the
programming 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 to
connect to any type of PROFINET I/O solutions either from GE or any third party. It offers enhanced
productivity, flexibility and performance advantages for virtually any type of control application in a range
of industries. PROFINET supports a variety of I/O without compromising system performance and can
operate in high-noise environments.
The RSTi-EP CPE100/CPE115 is secure by design, incorporating technologies such as Trusted Platform
Modules (currently disabled) and verified boot. Centralized configuration allows encrypted firmware
updates to be executed from a secure central location.
