Highlights include:

 A built-in PACSystems RSTi-EP PLC CPU

o User may program in Ladder Diagram, Structured Text, Function Block Diagram.

o Contains 1Mbytes 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 2k 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.

 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 in Figure 1.

 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).
