PCI Slot / IRQ
Shows in which logical PCI slot the card was detected and which IRQ is assigned to it. The IRQ is unused.
Search...
Searches for all connected FC750x channels. Select those required. In the case of an FC7502 both
channels A and B appear. These behave in logical terms like two FC7501 cards.
PCI-Cfg...
In which the address of the FC750x is set in the lower memory area (below 1 MB) of the PC.
Scan the bus...
The Sercos ring is scanned here, and all devices found are added to the device. In the case of Beckhoff
boxes the configuration is read precisely.
Data rate
The Sercos baud rate is set here. 2 Mbit/s, 4 Mbit/s, 8 Mbit/s and 16 Mbit/s can be selected.
Transmission power
The power of the transmitter is set here, depending on the length of optical fiber being used.
Operation mode
The FC750x can be operated as a Sercos master and as a Sercos slave. In either of these operating modes,
the card can be operated as the synchronous master (the PC and other synchronous devices receive their
clock from the sync master) or as a sync slave (the card, or the card channel, receives the synchronization
signal from the other channel or from another card over the sync cable [} 10]). There can only be one
synchronous master within one PC. If both channels of a FC7502 are used, then only the A-channel (the
channel closest to the motherboard) can be used as the sync master.
