Parameters
Data type Description
Interconnection
F-KEYS
Word
Reserved
RNG_BUSY
Bool
This output passes the state of the
effective range.
0 = effective range free,
1 = effective range in use
You can detect if the
effective range is free or in
use with this output.
You use this output, for
example, to control a light
that indicates the allocation
of the effective range in the
plant.
DIAG
Word
This output indicates which of the HMI
devices with permission to log on in the
effective range are actually logged on.
Bit 0: 1st panel logged on
Bit 1: 2nd panel logged on
Bit 2: 3rd panel logged on
Bit 3: 4th panel logged on
With F_FB_RNG_16:
Bit 4: 5th panel logged on
...
Bit 14: 15th panel logged on
Bit 15: 16th panel logged on
You can evaluate the DIAG
output in your user program.
Enable inputs EN and ENO
When you call a fail-safe block, the enable input EN and enable output ENO appear
automatically.
Please observe the following:
● Do not connect these I/Os.
● Do not set "0" for these I/Os.
● Do not evaluate these I/Os.
Validity
This description applies to the following F FB:
● F_FB_RNG_4, version 1.0
● F_FB_RNG_16, version 1.0
When the term "F_FB_RNG_n" is used, the information applies to both F-FB.
Note
Insert the FC 176: F_BO_W and FC 177: F_W_BO blocks into your safety program since
these blocks are called by F_FB_RNG_n. You can find these blocks in the Distributed Safety
F library in the F Application Blocks block container.
