The 2500P-ACP1 Application Coprocessor module is a general-purpose auxiliary controller that enhances

the capabilities of all Siemens Series 505® and CTI 2500 Series® PLC systems. This Advanced Function

Module (AFM) includes high-speed processing and multi-protocol communications support to

provide existing systems with a significant increase in performance and functionality.

The 2500P-ACP1 generally runs as a PLC coprocessor performing complex logic/math functions,

data logging, and communications with external devices. Although the 2500P-ACP1 can operate

as a stand-alone controller, the application generally requires data transfer between a host PLC

and the module.

The 2500P-ACP1 supports Ethernet communications through two 10/100Mb Ethernet ports and

RS-232/RS-422 connections through the serial port.

Embedded client and server protocols can be used for data transfer with other controllers and

devices. All message processing for client operation (request triggering, packet send/receive,

message validation, data insertion/extraction, and error handling/retries) is done in the module

with no PLC logic required.
