FOUNDATION Fieldbus Diagnostics Module

FOUNDATION Fieldbus Diagnostics Module

FOUNDATION Fieldbus network diagnostics has never been so open and easy. The ComBricks Diagnostic Module is able to permanently check the condition of the H1 physical layer. By means of a web server the signal quality of the connected devices can be inspected and emails inform the user about critical events. Notifications and remote access assure an optimal network uptime and reduced maintenance costs.

Request offer


The ComBricks FOUNDATION Fieldbus Diagnostics Module is not an active device and therefor does not require an address. It passively measures the network condition and can be wired parallel or series to/in an existing H1 segment.

FF modules can be combined with PROFIBUS DP and PA diagnostics modules to offer a complete installation overview to the user.
