FOXBORO FBM223 Communication Interface Module

The FBM223 PROFIBUS-DP™ Communication Interface Module provides an interface between PROFIBUS-DP slave devices and the I/A Series® system.

Key features of the FBM223 module are:

Conforms to PROFIBUS-DP Fieldbus

specifications：

Provides full support for all device variables and diagnostic messages.

Integrates PROFIBUS slave device data into an I/A Series control database.

The FBM223 and its associated termination assembly (TA) are suitable for installation in Class 1, Division 2 and Zone 2 locations.

OVERVIEW：

The PROFIBUS-DP Communication Interface Module (FBM223) provides an interface between PROFIBUS-DP slave devices — such as motor drives, I/O modules, and field I/O devices — and the I/A Series system.

PROFIBUS is a vendor-independent, open fieldbus standard for a wide range of applications in process and manufacturing. Vendor independence and openness are guaranteed by the PROFIBUS Fieldbus standard EN 50170, which specifies the functional, electrical, and mechanical characteristics for a serial transmission bus. 

Without the use of repeaters (non-expanded bus configuration) up to 31 slave stations can exist on a PROFIBUS-DP bus. Depending on the selected data transfer rate, cabling distances up to 1200 m (3960 ft) are possible without the use of repeaters.

The use of repeaters provides for expansion of the bus, allowing a greater number of slave devices per FBM223 port, up to 91.

For a given system, with the use of repeaters the maximum number of slave devices supported on an FBM223 port is dependent on the amount of I/O that is configured per device for access by the FBM223.
