CTI 2500-CPU-27APR2023 Programmable Controllers
CTI 2500-CPU-27APR2023 Programmable Controllers
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.

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.
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).
