Description
Additional information

The Siemens SIMATIC ET 200B is a compact, distributed I/O module belonging to the ET 200 product family, designed for use with the SIMATIC S5 and S7 programmable logic controller systems. The part number 6ES7133-0BL00-0XB0 identifies a digital output module within the ET 200B series, intended for decentralized peripheral applications in automation environments. It communicates with the central PLC via the PROFIBUS-DP fieldbus protocol, enabling efficient data exchange over longer distances.

The ET 200B series modules are characterized by their compact, flat housing design, which integrates the terminal block and electronics into a single unit for simplified installation. The 6ES7133-0BL00-0XB0 is a digital output module providing 16 digital outputs with 24 V DC signal levels, suitable for direct connection to actuators and solenoid valves. The module connects to the PROFIBUS-DP network through a dedicated bus connector and supports standard diagnostic functions for fault detection and reporting. Its design allows for tool-free wiring and straightforward replacement in the field.

The SIMATIC ET 200B modules are widely deployed in manufacturing automation, conveyor systems, packaging machinery, and process automation where distributed I/O is required to reduce wiring complexity. The decentralized architecture allows I/O points to be located close to the field devices, minimizing cable runs and improving system response times. This module is particularly suited for applications in automotive production, food and beverage processing, and general factory automation where reliable digital output control is essential.

Common Diagnostic Codes

BF (Bus Fault): PROFIBUS-DP communication failure detected; the module cannot communicate with the DP master.
Check PROFIBUS cable connections, termination resistors, and bus address settings. Verify the DP master configuration matches the module address.
SF (System Fault): Internal module fault or configuration error detected by the ET 200B station.
Check module configuration in the DP master. Replace the module if the fault persists after re-parameterization.
Output Short Circuit: A short circuit or overload condition has been detected on one or more digital outputs.
Disconnect the load on the affected output channel, identify and resolve the short circuit, then re-enable the output.
Parameter Assignment Error: The module has received incorrect or incompatible parameter data from the DP master during startup.
Verify the GSD file and hardware configuration in the engineering tool. Re-download the configuration to the DP master.
Supply Voltage Fault: The 24 V DC supply voltage to the module is absent or out of tolerance.
Measure the 24 V DC supply at the module terminals. Check the power supply unit and wiring for faults.
Watchdog Timeout: The DP master has not communicated with the module within the configured watchdog time, causing the module to enter a safe state.
Check PROFIBUS network integrity and master CPU status. Restart the DP master and verify bus cycle time settings.

Frequently Asked Questions

What communication protocol does the 6ES7133-0BL00-0XB0 use?

The module communicates via PROFIBUS-DP, connecting to a DP master such as a Siemens S7 or S5 PLC CPU or a CP communication processor.

How many digital outputs does this module provide?

The 6ES7133-0BL00-0XB0 provides 16 digital outputs at 24 V DC with a maximum current of 0.5 A per channel.

Is this module compatible with the SIMATIC S7-300 PLC?

Yes, the ET 200B modules can be used as distributed I/O with SIMATIC S7-300 and S7-400 systems when configured via a PROFIBUS-DP master interface.

What is the supply voltage required for this module?

The module requires a 24 V DC supply voltage for both its electronics and the output load circuit.

Can the module be replaced without special tools?

Yes, the ET 200B series is designed for tool-free wiring and straightforward field replacement, as the terminal block and electronics are integrated into a single compact housing.

Troubleshooting

BF LED is lit and module does not communicate with the PLC

Check the PROFIBUS-DP cable connections at both ends of the segment, verify bus termination is active only at the two physical ends of the bus, and confirm the module's PROFIBUS address matches the configuration in the DP master.

Correct any wiring faults, ensure proper bus termination, and re-download the hardware configuration from the engineering software (e.g., STEP 7 or TIA Portal) to the DP master.

Outputs do not switch despite correct PLC program

Verify the 24 V DC load supply is present at the module terminals. Check whether the SF or output fault LED is active, indicating a short circuit or overload on an output channel.

Restore the 24 V DC supply if absent. Identify and remove any short-circuited load. Reset the module by cycling power after resolving the fault condition.

Module not recognized by DP master after replacement

The replacement module may have a different PROFIBUS node address set, or the GSD file used in the hardware configuration may not match the module variant.

Set the correct PROFIBUS address on the replacement module using the address switches. Verify the GSD file in the engineering project matches the 6ES7133-0BL00-0XB0 module type and re-download the configuration.

Intermittent communication faults on PROFIBUS segment

Measure the bus signal quality using a PROFIBUS diagnostic tool. Check cable shielding, connector quality, and whether the segment length exceeds the maximum allowed for the configured baud rate.

Replace damaged cables or connectors, ensure proper shield grounding at one end, and reduce the segment length or lower the baud rate if the cable run is too long.

Module outputs remain in safe state after PLC restart

The DP master watchdog may have triggered, placing outputs in their parameterized safe state. Check the CPU status and PROFIBUS network for errors that occurred during the restart sequence.

Confirm the PLC CPU is in RUN mode and the PROFIBUS network is fully operational. Re-establish communication by cycling the DP master or performing a warm restart of the CPU.
