CTI 2590-EF / 2591-EF 16-Point Isolated Discrete Output Modules

DESCRIPTION

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

process performance to CTI’s 2500 Series® Control Systems. The Compact Controller

easily handles small to large discrete and process applications.

Compact processors have the same features and performance as our Classic processors,

and include PID loops, alarms and special mathematical functions to make them perfect

for process applications.

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.

FEATURES

• Executes the same application programs that were developed for the CTI 2500

Series® or Simatic® 545 / 555 CPUs

• Built-in Ethernet and USB ports for programming

• Built-in micro-SD Flash card for firmware update from flash

• Built-in Profibus and RS485 Remote I/O on C200 and C300 models

• Up to 512K bytes memory, 8192 I/O points, 512 PID loops & 512 alarms,

depending on model

• Programmable using Workshop or FTsolution for APT® Compact

• Also supports programming serially using TISoft, and APT

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.

User Configuration

The following differences in the user configuration should be noted:

1. Allocation of CS memory is not supported. The CTI 2500 Series® controller uses high

speed DRAM to store and execute compiled SF programs and subroutines.

Consequently, CS memory is not required.

2. User allocation of User Subroutine memory is not supported. 

The CTI 2500 controller does not support user subroutines (XSUB).

See XSUB description above.

3. A time slice for Report by Exception (RBE) is not supported.

Some alternative solutions exist. Please consult us with your exact configuration.

4. A new time slice, Network Communications, has been added to support the local Ethernet port.
