F376-OPC Field-Bus InterBus-S Card

Identification code (ID Code)

The welding control devices are considered by the InterBus-S net as digital devices

belonging to the Profile-conforming digital devices with I/O addresses (PROFILE DIO). This

functional category corresponds to the

decimal identification code

(ID code)

47 (2f

hexadecimal)

11.5

Error conditions with the control device shut down

During InterBus-S line working, the communication protocol recognizes two shut-down

conditions of the control device:

1 – When the control device is still OFF and the F376-OPC card is powered (24V on P25),

by starting the communication on the InterBus-S line, the F376 card generates the

ID38

hex

“µP_Not_Ready” identification code on the bus to tell the Bus Master that the

device has not been initialized.

2 – Under normal operating conditions of the InterBus-S Bus, if the control device is

switched OFF, the F376-OPC card generates a “Module error” type error and sends a

“Peripheral error indication” signal to the Bus Master.

11.6

Optical power regulation

The SUPI 3 OPC expands the data transmission functionality thanks to the help of the

optical transmission techniques. This device is able to autonomously regulate the optical

power transmitted by the optical fiber cables (FOC), thus compensating the thermal effects

and the component aging.

The automatic regulation is only possible in the case of a communication occurring through

a device with this same functionality. In other cases the optical intensity is kept to a

standard level, which is settled by the JP23-JP24-JP25-JP26-JP27 bridge configuration, and

is determined through a particular procedure carried out while producing the card.

WARNING

It is in any case forbidden to change the JP23

JP27 bridge configuration during the card

setup and/or replacement.
