Siemens 6ES74603AA010AB0

Technical Parameters

Multi-Segment Optical Isolation

Enables fiber-optic communication between central and expansion racks via PCF cables (6XV7 875-5A** series), achieving 50Mbit/s bandwidth with ≤0.1dB/km attenuation tolerance at 650nm wavelength.

Dynamic Address Assignment

Automatically allocates expansion rack addresses (1-21) through optical ID coding, requiring matched IM 461-3 receiver modules with ±5ns clock synchronization accuracy.

Optical Power Budget

Supports link distances up to 100m using 200/230µm HCS fiber, with integrated RX/TX power monitors triggering SF alerts at <-18dBm receiver sensitivity thresholds.

Frame Synchronization

Hardware-based jitter reduction circuit limits cycle time deviations to ±25ns across 4 cascaded expansion racks, compatible with synchronous OB61 interrupt processing.
