Bus Architecture and Network Integration

This module serves as the central bus connection for ET 200M stations. It interfaces with the PROFIBUS DP network via RS-485. The 9-pin D-sub connector ensures secure and reliable termination. This architecture supports high-speed data exchange with DP masters.

I/O Module Support and Slot Capacity

The bus module accommodates up to 8 I/O modules in its slots. Users can mix digital, analog, and function modules freely. This flexibility supports various application requirements within one station. The station grows easily by adding modules as needed.

Diagnostics and Fault Indication

Onboard diagnostics monitor bus communication and module status. The module reports faults to the DP master for alarm generation. Users receive immediate notification of station or module issues. This diagnostic capability simplifies troubleshooting significantly.

Power and Energy Consumption

The bus module draws only 0.3 W from the station power supply. This low consumption supports efficient station operation. The module passes power to connected I/O modules through the backplane. No internal batteries or storage devices exist.

Mechanical Construction and Physical Attributes

This module measures 125 mm wide and weighs 0.35 kg. The standard ET 200M form factor fits system racks perfectly. A bus connector provides external network access. DIN rail mounting ensures secure installation.

Status Indication and Visual Feedback

A green power LED confirms supply voltage to the module. A red bus fault LED indicates communication issues. Operators can quickly assess station status from the front panel. This feedback assists during system startup and operation.

Certifications and Safety Standards

The 6ES7195-7HD80-0XA0 holds CE, UL, cULus, and FM certifications. These approvals confirm compliance with international industrial standards. Each module undergoes quality testing before shipment. This commitment ensures reliable bus communication.
