Product Introduction
The ABB Bailey IMCKN02 clock network module is a critical time synchronization component in the Bailey INFI 90 distributed control system (DCS) . Designed to manage and distribute a consistent and synchronized time reference across multiple controllers and processors, it ensures precise coordination between various automation functions in complex industrial environments.
The IMCKN02 plays a central role in aligning time-stamped events, recording the order of events, and enabling real-time control operations. By maintaining unified clock data throughout the system, it improves process diagnostics, increases reporting accuracy, and supports deterministic control behavior, especially in large-scale or safety-critical applications.

Frequently Asked Questions (FAQ)
-
Q: What is the core function of the IMCKN02 Clock Network Module?
A: It synchronizes internal clocks across all INFI 90 controllers and processors to ensure consistent time-stamping and coordinated operations. -
Q: Does the module support external time references like GPS?
A: While the IMCKN02 primarily uses its internal oscillator, it can be interfaced with an external sync source through system configuration. -
Q: What happens if the external time signal is lost?
A: The module switches to its internal oscillator, maintaining basic clock functions without halting the system. -
Q: How is the IMCKN02 installed?
A: It is mounted in a standard ABB Bailey INFI 90 rack and connects via the system backplane. -
Q: Can the module synchronize across multiple remote stations?
A: Yes, when combined with INFI-NET communication, it supports wide-area time sync across remote nodes. -
Q: Is the IMCKN02 hot-swappable?
A: No, power should be removed before installation or replacement to avoid damage. -
Q: How do you know the time sync is working correctly?
A: LED indicators on the module show sync status, and system logs confirm time alignment. -
Q: Can this module be used in safety instrumented systems?
A: It is suitable for use in support systems where accurate time coordination is required, but safety classification depends on system integration. -
Q: What is the sync accuracy of the internal oscillator?
A: It typically maintains an accuracy within ±1 millisecond, sufficient for most industrial applications. -
Q: Is periodic calibration required for the IMCKN02?
A: Generally, no calibration is needed unless specified by site-specific reliability protocols or in the presence of significant drift over time.
