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.

IMPORTANT NOTE: This product includes a lithium battery for backing up the user program, retentive variables, and  system diagnostics. For safety in transportation, the battery is installed but disabled. Prior to putting this product into  service, you MUST move dipswitch SW1 to the CLOSED position to enable the battery. 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. 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. User Configuration The following differences in the user configuration should be noted: 1. Allocation of CS memory is not supported. The CTI 2500 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. I/O Support The following are not presently supported. This is subject to change. • Interrupt I/O Support of Special Function Modules Most CTI and Siemens special function modules are supported. A complete list showing the compatibility status by module part number is maintained in the Technical
