2500P-ACP1 Application Coprocessor

The 2500P-ACP1 module is a general-purpose auxiliary controller that enhances the capabilities of all CTI 2500 Series® and SIMATIC® 505 PLC systems. This Advanced Function Module includes high-speed processing and multi-protocol communications support to provide existing systems with a significant increase in performance, features, and functionality.

NOTE: 2500P-ACP1 works with Simatic®/TI 545/555 CPUs using 2572, 2572-A, or 505-CP2572 Ethernet modules, or using a high-density word interface over the backplane (with performance restrictions).  However, for best performance we recommend CTI 2500 Series® Processors when using 2500P-ACP1.
