The Siemens 6ES7141-6BG00-0BB0 is a PROFINET IO module with one byte of digital input (DI) plus one byte for quality information (QI). It connects via two M12, 4-pin, D-coded ports carrying a 100 Mbit/s full-duplex PROFINET interface.
What the key specs mean for fit
IRT is configurable from 250 µs to 4 ms in 125 µs steps, with a maximum jitter of 10 µs — this buys deterministic I/O update for high-speed lines or motion camming where a standard RT update isn't tight enough. Wire-break detection is active per channel when input current drops below 0.3 mA, letting a PLC flag a cut sensor cable before the line stops. Temperature rating spans -40 to 60 °C, so the module goes into an uninsulated pendant station or a cabinet sitting in a bake oven without a heat exchanger. It supports shared device with two EtherNet/IP scanners and runs on redundant controller configurations.
The module measures 45 × 200 × 48 mm (W × H × D) and uses two M12, 4-pin, D-coded ports.
