• 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 16 simultaneous SRTP
Server connections (or) up to 8 simultaneous Modbus TCP Server connections.
o 8 Clients are permitted; each may be SRTP or Modbus TCP or a Combination of both.
o up to 8 simultaneous Class 1 Ethernet Global Data (EGD) exchanges.
o When used in combination for optimal performance, user must not exceed 4 Channels
for Server (Modbus/SRTP) & 4 Channels for client (Modbus/SRTP), 8 PROFINET nodes and
8 EGD data exchanges.
• Ability to display serial number and date code in PME Device Information Details.
• Operating temperature range -40C to 70C (-40F to 158F).
GFK-2958E
Standalone controller for RSTi-EP
The PACSystems* RSTi-EP EPSCPE100, is an enhanced performance
standalone 1GHz programmable controller equipped with 1MB of
user memory and four Ethernet ports to run real time deterministic
control applications. LAN1 is dedicated to highspeed Ethernet and
LAN2 comprised of 3 switched ports configurable as either an
embedded Ethernet controller or an embedded PROFINET controller,
which provides the PROFINET functionality and supports only simplex
mode of operation. It is a standalone PLC that supports distributed
I/O. From now on in rest of the document this controller will be
referred to as CPE100.
Highlights include:
• A built-in PACSystems RSTi-EP PLC CPU
• User may program in Ladder Diagram, Structured Text, Function
Block Diagram.
• Contains 1Mbytes of configurable data and program memory.
• Supports auto-located Symbolic Variables that can use any
amount of user memory.
• Reference table sizes include 2k bits for discrete %I and %Q and
up to 2k words each for analog %AI and %AQ. Bulk memory (%W)
also supported for data exchanges.
• Supports up to 512 program blocks. Maximum block size is 128KB
• Supports two independent 10/100 Ethernet LANs. LAN1 has only
one port and is dedicated to highspeed Ethernet and whereas LAN2
comprises of 3 switched ports configurable as either an embedded
Ethernet controller or an embedded PROFINET controller. All four
ports are located on the front panel, as shown aside.
