System Architecture & Signal Flow
The LSZ-44-S2 operates as a central processing unit within a MELSEC modular rack or standalone configuration. The CPU module communicates with I/O expansion modules via the MELSEC backplane bus, enabling deterministic data exchange at each scan cycle. Field signals (digital inputs/outputs, analog signals) are routed through dedicated I/O modules, while the CPU executes the user ladder/structured text program and updates output states accordingly. Communication to SCADA, HMI, or upper-level systems is handled via the integrated serial or network interface port.
Refer to the MELSEC system configuration manual for detailed rack layout, power budget calculations, and bus cycle timing specifications.
