11. F376-OPC Field-Bus InterBus-S Card (Profile F-IBS/03)
11.1 Characteristics
The F376-OPC card enables the welding I/O functions towards the field to be managed, as
an alternative to the IOE field cards. This data communication occurs by optical fiber
transmission through a serial bus, compatible with the InterBus-S protocol.
InterBus-S is one of the most common communication standards in the field of automation.
The F376-OPC card enables exchange of up to 12 words. The actual amount of exchanged
data depends on the communication Profile defined for any specific application. The word
“Profile” identifies a particular configuration of the exchanged data. The F376-OPC card is
associated to the F-IBS/03 Profile type.
From the functional standpoint, the card is divided into two separate parts:
the first part comprises the interface electronics towards the control device
and is powered by the internal bus; the second part comprises an optical
interface circuit towards the field powered by an external 24Vdc through the
P25 connector.
Thus the InterBus-S serial communication, as it is autonomously
powered, is not interrupted when the power to the control device is OFF.
The InterBus-S interface is achieved through the IBS SUPI 3 OPC (

security and an independent diagnostics capability in the quality and level
of the optical fiber based signal.
11.2 Optical connectors InterBus-S
The connectors used for the optical fibers are of the F-SMA type, in
accordance with the
InterBus-S DIN 19258
