Link View - 32Mbit Flex - IBA ibaFOB-D Manual

8.1.6 Link view – 32Mbit Flex
Figure 19: Link information at 32Mbit Flex
The screenshot above shows the information you see when the link is in 32Mbit Flex
mode. Up to 15 devices can be connected in a ring topology per link. In the signal tree
on the left side, the links 1 – 15 below the ibaFOB-D board correspond to the address
set by the rotary switch at the connected device.
Additional items, which are specific to 32Mbit Flex:
"Link" area
 Time between telegrams
Time between two telegrams measured by the ibaFOB-D board. It should be equal
to the configured frame time.
 Mode
Status of the connection mode
Ring: one or more devices (cascade) are bidirectionally connected and the FO ring
is closed.
Open chain: Only the fiber optic input is connected to a device. The output is not
connected or the FO ring is interrupted.
 Mirror mode
Indicates whether morror mode is disabled or enabled. If mirror mode is enabled,
the display shows whether the board is configured as master or slave system. De-
scription of mirror mode see chapter 8.1.6.1.
 Roundtrip delay
Telegram cycle in the closed FO ring. The time depends on the number of the con-
nected devices in the ring (approx. 2 µs per device).
Due to the roundtrip delay the data of the connected devices might be captured
asynchronously (up to one telegram cycle).
