PCI bus slot (base address) and optical fiber ring
Logical number of the PCI bus slot (or base address in the memory area) allocated to the Lightbus card in the PC.
For Lightbus card FC2002, the optical fiber ring (-A or -B) used by this device entry is appended to the number of the PCI bus slot.
Search
Searches the computer for existing Lightbus cards and sets the logical number of the PCI bus slot or the address accordingly.
PCI Cfg
In the delivery state, the base address of the Lightbus card is in the range above 1 MB (32-bit address). The PCI configuration dialog can be used to place the base address of the Lightbus card in the range below 1 MB (DOS address). Only use this option if absolutely required by your PC.
Check number of boxes
If this option is selected, during card initialization the number of boxes that are physically present (Bus Couplers, modules) is compared with the number that was entered under this card in the System Manager. If the numbers do not match, an error message is generated.
System Start Despite Optical Fiber Error:
If this option is selected, system start-up is not aborted if a Lightbus error occurs during TwinCAT start-up. Instead, a warning is issued.
K-bus update with broadcast telegram (0xB0)
If this option is selected, the K-bus update via broadcast telegram is carried out simultaneously for all Bus Couplers, instead individually for each Bus Coupler.
Reserved CDLs
Each fieldbus channel has eight priority channels (CDLs), which can also freely be used by the TwinCAT System Manager. If individual CDLs are to be reserved for special applications, they should be marked here. They are then no longer available for the TwinCAT System Manager.
Firmware
Indicates the firmware version of the Lightbus card. For older Lightbus cards (e.g. C1220) only Found is displayed.
