It will take several minutes for all the data to be gathered to complete
this window. This is primarily a list of the Function Blocks that are in
the attached Fieldbus devices. Until all the data is complete, you will
see the “working” hour glass.
Wait until the software is finished gathering data. It will be finished
when the working icon disappears. Although, you see nothing going
on, there is a lot of Fieldbus communication going on.
If you see:
– yellow circles with an “!” exclamation mark in them, that
indicates that the FFCT configuration software doesn’t
understand that device. This is a caution and needs to be
addressed.
– UNK to the right of a the name of a Function Block, that means
again that the FFCT doesn’t recognize that Function Block.
These indicate that the DD’s for those devices were not loaded,
or did not match the data that the FFCT read from the device.
ATTENTION
!
You can’t use a Function Block with a UNK note.
The UNK is a show stopper. You need to get a
more current DD from the device manufacturer.
If you are using both ports on
a single CN2FF, you must:
1. Check both ports, now.
2. Configure both Fieldbus
networks.
3. Perform two downloads.
The reason you must do both
Fieldbus networks at the same
time is that when you restart
this Add Links function, you
delete the data from the first
download.
