Specification summary for sourcing
The Siemens 6ES7141-6BH00-0BB0 is a PROFINET IO module for the ET 200SP family. It provides digital inputs over two M12 D-coded ports, with IRT (Isochronous Real-Time) communication. The IRT cycle time is adjustable from 250 µs to 4 ms in 125 µs increments, and the jitter is bounded at 10 µs. This makes the module suitable for applications requiring deterministic update timing, such as high-speed machine control or precisely coordinated motion sequences. The module also supports MRP for media redundancy, LLDP for topology discovery, and SNMP for network monitoring.
Environmental and electrical ratings
Signal thresholds are defined: for signal '0', -30 to +5 V; for signal '1', +11 to +30 V. The module accepts 2-wire sensors and provides 2 bytes of digital input data plus 2 bytes for quality information (QI). Counter function is not available on this variant.
