It retrieves auxiliary process variables and calibration data by modulating high-frequency digital signals directly onto the analog loop without affecting the primary variable measurement. This digital overlay enables real-time instrument diagnostics and loop monitoring inside the CENTUM control network. Internal filter circuitry suppresses potential line noise to prevent attenuation of the frequency-shift keying (FSK) digital transmission.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does the module support online maintenance inside the Field Control Station rack?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Yes, the module supports hot-swapping under powered conditions.
