Serial Communication and Controller Configuration
The two RS-232 ports support serial communication using DH-485, DF1, and ASCII protocols. The isolation difference between Channel 0 and Channel 1 matters when selecting connection points and evaluating electrical interfaces. Confirm the required protocol, cable, and port configuration before connecting the controller to external equipment.
I/O Expansion
The 1769-L31 supports up to 16 I/O modules distributed across a maximum of three I/O banks. This capacity defines the stated module-count limits, but the final configuration must also satisfy the applicable power supply, interconnection, and system layout requirements.
