Therefore, the controller supports modular I\/O density scaling with up to 16 connected I\/O modules distributed across three I\/O banks.\u003c\/p\u003e\n\u003cp\u003eThe controller provides two RS232 serial communication ports. Channel 0 supports full electrical isolation, while Channel 1 provides a non-isolated serial interface. In addition, the module supports DH485, DF1, and ASCII communication protocols for serial device integration.\u003c\/p\u003e\n\u003cp\u003eThe CompactLogix architecture uses firmware-controlled processor functions to coordinate application execution, I\/O scanning, and serial communication tasks.
