IO-Link Master for Hygienic Zones
The 6ES7148-7JH00-0BB0 is a SIMATIC ET 200clean IO-Link master with 8 ports in 8x M12 connectors, split 4x Class A and 4x Class B for sensor/actuator flexibility. Four onboard digital inputs (DIQ 24 V DC) handle valve feedback or proximity without an extra slice. Multi-fieldbus support—PROFINET IO, Ethernet/IP, Modbus TCP—lets the module drop into any control architecture common in hygienic zones without a gateway.
Fieldbus and Redundancy
Shared device capability allows the module to serve two controllers simultaneously, reducing hardware count in redundant CPU schemes. MRP (Media Redundancy Protocol) and S2 system redundancy keep communication intact during line or device faults. Channel diagnostics report fault location at the I/O level. I&M0…4 consistently identifies the module in the TIA Portal or other engineering tools.
