COMPATIBILITY OVERVIEW

The CTI 2500 Series® Processor is designed to be compatible with customer applications 

that use the Simatic® 545 and 555 controllers. While the CTI 2500 matches or exceeds

the capabilities of these processors in most aspects, there are a few areas in which the

CTI 2500 operates differently.

Relay Ladder Logic

The RLL used in the controller provides equivalent instructions for all Simatic® 555

instructions except the XSUB instruction. External subroutines are not supported.

If you download a program containing the XSUB instruction, it will be ignored.

In many cases XSUB is used for communications with Siemens® Profibus HMI panels.

For these installations we have a CTI program free on our website which replaces the XSUB.

For XSUB uses other than Siemens® HMI panels, CTI and our partners can develop XSUB

replacement software using SF programming. Please contact us.

DESCRIPTION

The 2500 Series® Controllers bring exciting new features and a new level of process

performance to Simatic® 505® Control Systems.

The C100 and C200 models easily handle medium to large discrete control applications,

as well as basic process applications. The C300 and C400 models are equipped to handle large

process applications with many PID loops and alarms and special mathematical functions.

The 2500 Series® Controllers are designed to seamlessly replace all Simatic® 545 and 555

controllers while providing much higher performance at lower cost. The controllers are

supported by a complete range of digital, analog, and specialized I/O modules, power

supplies, and I/O bases, all available from CTI.

The 2500S family of Slice I/O modules expands the capability of 2500 Series® Systems

to include small drops of I/O connected over Ethernet.

Slice I/O modules communicate to 2500 Series® Processors using CAMP protocol

and read/write directly to the PLC memory or I/O image table. This allows transparent

integration into the 2500 Series® system without the requirement for any complicated

configuration step.  Ethernet connection to the CPU can be accomplished using the

on-board port on 2500-Cxxx Processors, using a 2572 / 2572-A Ethernet module,

or using the 2500P-ECC1 Ethernet Communications Coprocessor. 

Note that when using 2572 or 2572-A modules, Slice I/O can be connected even to

legacy Siemens® and Texas Instruments PLCs.

Several models of Slice I/O are available with different mixes of I/O and with additional

communications options including RS232/485 and 900MHz radio.

Slice I/O modules feature Universal Analog Inputs which allow connection of 0-5V, 

0-20mA, thermocouple, and RTD sensors.

All Slice I/O modules can also be configured to communicate over Ethernet using Modbus-TCP.

The 2500 Series® Slice I/O System is designed for use in a broad range of applications,

including those that require discrete and analog control. It is compatible the the 2500

Series® System, and offers modularity down to a single module, without the need for an

I/O base and RBC.  Slice I/O 23-xxxx modules operate from 24VDC power,

while 26/27-xxxx models operate on 12VDC power (design for solar cell applications).

All Slice I/O modules communicate with a remote 2500 Series® CPU using Ethernet to

read/write directly to the PLC memory or I/O image table.

This allows transparent integration into the 2500 Series® system without the requirement

for any complicated configuration step.  Ethernet connection to the CPU can be accomplished

using the on-board port on 2500-Cxxx Processors, or using a 2572 / 2572-A Ethernet module.

Note that when using 2572 or 2572-A modules, Slice I/O can be connected even to legacy

Siemens® and Texas Instruments PLCs.

Several models of Slice I/O are available with different mixes of I/O and with additional

communications options including RS232/485 and 900MHz radio.

• Compatible with the 2500 Series® System

• Single-module modularity without the need for an I/O base and RBC

• Can be connected to legacy Siemens/TI PLCs with CTI communications card
