Starts with 2 bytes offset
(the 2nd and 3rd UINT (class168 / instance 2 and 3)
= 1st UDINT (class173 / instance 1) etc.)

Specific
Get/Set
BK_FBINP_
VAR_CNT
UINT
Defines the number of bytes from the
PLC-fieldbus-variables (inputs) which
will be added to the assembly object
(this count will be added to the consu-
med path – assembly instances 1..3)
101 (0x65)
Specific
Get/Set
BK_FBOUT
_VAR_CNT
UINT
Defines the number of bytes from the
PLC-fieldbus-variables (outputs)
which will be added to the assembly
object (this count will be added to the
produced path – assembly instances
4..9)
Example:
The example comes from the DeviceNet Coupler point of view:
-> Configuration Coupler:
input process image 12 byte,
output process image 10 byte
-> BK_FBINP_VAR_CNT = 0; BK_FBOUT_VAR_CNT = 0
poll connection: -> 12 byte produced
-> 10 byte consumed
-> BK_FBINP_VAR_CNT = 4; BK_FBOUT_VAR_CNT = 3
poll connection:
-> 15 byte produced
(12 byte input process image + 3 byte PLC output fieldbus variables)
-> 14 byte consumed
(10 byte output process image + 4 byte PLC input fieldbus variables)
