CTI 2589-A 8/16/32-Point Universal Discrete Input Module

Special Function Programs

The controller compiles all SF programs and subroutines. 

They are compiled in the following situations:

• When a user program is downloaded to the PLC, if the SF Program or subroutine is enabled,

• When the SF program or subroutine is enabled, if the SF program has been modified,

• During a Power Up start (following the application of power).

Programs that contain errors will not be enabled. During a program download,

Workshop will display a message indicating the error. Once you acknowledge the message,

the download will continue, leaving the program disabled. You must correct the programming

error before the program or subroutine can be enabled. User Programs originally written

for the Simatic® 505 PLC may contain undetected errors, if the programs were not originally

compiled. This can occur because the SF interpreter never attempts to execute the instruction

due to the branching logic. A common problem is that additional ENDIF statements are included

or the correct number of ENDIF statements is not present.

Unlike the Simatic® 555. there are no restrictions regarding the instructions that can be used

in a compiled program.

The 2500-PADP is a Power Supply Adapter that enables the use of CTI 2500

Series® power supplies within legacy Texas Instruments Series 500 I/O bases.

This adapter offers a seamless upgrade path, allowing you to modernize your

Series 500 system without a complete system replacement.

You can immediately replace failed Series 500 power supplies with reliable

and compatible CTI 2500 Series® replacements. Subsequently, when budget

and/or time permits, you can then transition to a full CTI 2500 Series® system

without losing your initial investment in the replaced power supplies.

The 2500C-8-AO is designed for CTI’s 2500 Series® Compact I/O System.

The module provides 8 outputs that can be configured for voltage or current

signals on a channel by channel basis.

The Ethernet ports are connected to an Ethernet switch incorporated into the

2500P-ECC1 module. This switch is also connected to the Ethernet controller

on the ECC1 microprocessor. This arrangement allows devices connected to

either port to communicate with the microprocessor and allows

communications between ports. The switch also provides hardware protection

against excessive broadcast/multicast traffic.

The 2500P-ECC1 Ethernet Communications Coprocessor provides state-of-the-art

features and performance for Ethernet communication when using CTI 2500

Series® Processors. It uses a dynamic memory cache to give extremely quick

response to queries from HMI systems, with no dependence on CPU scan time.

It also provides a fully configurable interface for setting up Modbus-TCP, and

CAMP client/server communications. Most importantly, it features a completely

new facility which provides peer-peer network communications between PLCs

using a new "report on change" protocol - Network Data Exchange.
