1 PACSystems™ RSTi-EP EPSCPE115 Standalone CPU Quick Start Guide GFK-3039C
User Features
The PACSystems RSTi-EP EPSCPE115 (or CPE115), is an enhanced performance
standalone 1GHz programmable controller equipped with 1.5 MB of user
memory and four Ethernet ports. It is designed to run real-time, deterministic
control applications and supports distributed I/O.
LAN1 is a dedicated high-speed Ethernet port. LAN2 is comprised of 3 switched
ports configurable as either an embedded Ethernet controller or an embedded
PROFINET controller supporting PROFINET simplex mode. All four ports are
located on the front panel, as shown in Figure 1.
The CPE115 is programmed and configured over Ethernet via PAC Machine
Edition (PME) software. It can control/process up to 2K I/O points.
Features include:
• A built-in PACSystems RSTi-EP PLC CPU
o User may program in Ladder Diagram, Structured Text, or Function
Block Diagram.
o Contains 1.5Mbytes of configurable data and program memory.
o Supports auto-located Symbolic Variables that can use any amount of
user memory.
o Reference table sizes include 2k bits for discrete %I and %Q and up to 32k
words each for analog %AI and %AQ. Bulk memory (%W) also supported
for data exchanges.
o Supports up to 512 program blocks. Maximum block size is 128KB.
• The embedded communications interface has dedicated processing
capability, which permits the CPU to independently support LAN1 and LAN2
with:
o Up to 16 combined SRTP Server and Modbus TCP Server connections out
of which Modbus TCP cannot exceed more than 8 connections (or) up to
