Introduction 11
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.
1.5 Migrating Series 90 Applications to PACSystems
The PACSystems control system provides cost-effective expansion of existing systems.
Support for existing Series 90 modules, expansion racks and remote racks protects your
hardware investment. You can upgrade on your timetable without disturbing panel
wiring.
▪ The RX3i supports most Series 90-30 modules, expansion racks, and remote racks.
For a list of supported I/O, Communications, Motion, and Intelligent modules, see
the PACSystems RX3i System Manual, GFK-2314.
▪ The supports most existing Series 90-70 modules, expansion racks and Genius
networks. For a list of supported I/O, Communications, and Intelligent modules, see
the PACSystems Installation Manual, GFK-2223.
▪ Conversion of Series 90-70 and Series 90-30 programs preserves existing
development effort.
▪ Conversion of VersaPro and Logicmaster applications to Machine Edition allows
smooth transition to PACSystems.
