Furthermore, the embedded I\/O architecture features sixteen 24 VDC discrete inputs, sixteen 24 VDC discrete outputs, four analog inputs, two analog outputs, and four high-speed counters, thereby optimizing local panel space while scaling control loops efficiently. Additionally, the backplane communication velocity handles up to two physical 1769 expansion modules seamlessly, ensuring deterministic response times across the entire rack configuration.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the 1769-L23E-QBFC1B controller support hot-swapping of expansion modules?\u003c\/p\u003e\n\u003cp\u003eA: No. Power must be removed from the system and external power supplies before installing or removing any 1769 I\/O expansion modules to prevent electrical arcing and memory corruption.\u003c\/p\u003e\n\u003cp\u003eQ: What is the maximum number of local expansion modules supported by this controller?\u003c\/p\u003e\n\u003cp\u003eA: This packaged controller supports a maximum of two (2) physical 1769 I\/O expansion modules connected directly to the right side of the CPU base.\u003c\/p\u003e\n\u003cp\u003eQ: Can the embedded serial port be configured for user-defined ASCII communication?\u003c\/p\u003e\n\u003cp\u003eA: Yes.
