Features:
- Thirty-two 24 V DC inputs are organized as two groups of sixteen.
- The TB 16SC connection adds the Smart Connect extension path.
- PROFIBUS-DP transfers input states and module diagnostic information.
Field voltage crosses a channel threshold before the corresponding process bit is updated.
Load groups keep their supply and common paths tied to the documented terminal organization.
ON, BF, group-error, and individual channel LEDs identify different parts of the signal path.
The Siemens 6ES7131-1BL11-0XB0 ET 200L-SC Digital Input Electronic Block may remain available for quotation and support beyond End-Of-Life (EOL) by the manufacturer (OEM).

Relating terminal groups to the process image
- Channels 1 to 16: The first group shares its assigned load and common terminals.
- Channels 17 to 32: The second group follows its separate documented group path.
- Signal thresholds: Input voltage determines whether the PLC reads a zero or one.
- Channel LEDs: Each green indicator follows the state of its individual input.
Extending the station from the TB 16SC interface
- Cable set: The short Smart Connect lead links the electronics block to the extension terminal block.
- Added modules: Configured digital or analog modules occupy the Smart Connect address area.
- Open interface: The SC cover closes an unused interface before operation.
- Project match: The hardware order and PROFIBUS configuration describe the same extension layout.
Moving field states from the input electronics to the controller
- Bus address: The station address identifies the block on PROFIBUS-DP.
- Transfer rate: The selected rate follows the segment configuration.
- Isolation: The channel section is galvanically separated from the bus interface.
- Cable length: Shielding and baud rate are checked against the documented segment limits.
Separating signal state from supply and bus conditions
- Channel status: Green LEDs report the individual input states.
- ON indicator: The electronics-supply LED shows the internal power condition.
- BF indicator: The red bus-fault LED identifies disrupted PROFIBUS communication.
- Group error: The red group indication signals a module-level diagnostic condition.
