What this slice does on the PROFINET line
The 6ES7144-6KD50-0AB0 is a distributed analog input slice sized 60 mm wide, 49 mm deep and 175 mm tall, intended to mount in the field close to the sensors. It reads resistive temperature sensors and standard thermocouples on the same channels, so one module covers both probe families on a single BOM line.
What governs the field-side wiring
Shielded cable runs are rated to a 30 m maximum, which is the distance ceiling between the slice and the sensor head — anything longer needs a head-mount transmitter or a different routing plan. That figure, not the PROFINET cable length, is the constraint that decides where the field box can physically live. Integration time is parameterizable in four steps — 1×, 4×, 16× and 64× the base cycle time — letting the controls integrator dial noise rejection against update rate per channel.

Lifecycle and sourcing posture
Lifecycle stage for the seed MPN is recorded as current, so the part is on the manufacturer's active line and is the correct order code for a new BOM. No L* successor is recorded on the ledger, so the 6ES7144-6KD50-0AB0 is not flagged for cross-reference to a newer variant — specify it as written.
