The AC 800M controller automatically detects the module via the CEX-bus. Engineers configure the specific port parameters (baud rate, parity, stop bits) using ABB Control Builder M software. For distances exceeding the standard RS-232 limit of 15 meters, we recommend using fiber optic converters to maintain signal integrity and prevent ground loop interference.\u003c\/p\u003e\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between the built-in COM3 port and the CI853A?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe CI853A provides two additional isolated ports, allowing for expanded connectivity and protocol diversity that the single built-in COM3 port cannot accommodate alone.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the CI853A support MODBUS RTU Slave mode?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The CI853A hardware specifically supports MODBUS RTU in Master mode only.
