specific
get/set
BK_FBC_CFG UINT
Contains configuration settings
Bit 0: =1 turns off displaying
current diagnostic messages via
MS LED. The diagnostic
messages, however, are still
transmitted via the fieldbus. Any
change to this setting is only
applied after a power-on cycle.
Bit 1..15: reserved
100 (0x64) specific
get/set
BK_FBINP_
VAR_CNT
UINT
Defines the number of bytes for
the PFC fieldbus variables
(inputs) to be added to the
assembly object (this number is
added to the consumption path –
Assembly Instances 1 … 3)
101 (0x65) specific
get/set
BK_FBOUT_
VAR_CNT
UINT
Defines the number of bytes for
the PFC fieldbus variables
(outputs) to be added to the
assembly object (this number is
added to the production path –
Assembly Instances 4 … 9)
(For PFC with software version SW 01.06 or higher):
102 (0x66) specific
get/set
BK_FBINP_
PLCONLY_VA
R_CNT
UINT
Defines the number of bytes for
the PFC fieldbus variables
(inputs) assigned to the assembly
object "Instance 11"
103 (0x67) specific
get/set
BK_FBINP_
START_PLC_V
AR_CNT
UINT
Defines the offset from the first
PFC input variables (the number
specified in Attribute 102 is
transmitted to PFC input variables
from this variable)
104 (0x66) specific
get/set
BK_FBOUT_
PLCONLY_VA
R_CNT
UINT
Defines the number of bytes for
the PFC fieldbus variables
(outputs) assigned to the assembly
object “Instance 10”
105 (0x67) specific
get/set
BK_FBINP_
START_
PLC_VAR
_CNT
UINT
Defines the offset from the first
PFC output variables (the number
specified in Attribute 104 is
transmitted to PFC output
variables from this variable)
Example:
This example is described from the perspective of the DeviceNet
TM
fieldbus
controller (750-806):
Configuration of the fieldbus controller:
Input process image 12 bytes,
Output process image 10 bytes
BK_FBINP_VAR_CNT = 0; BK_FBOUT_VAR_CNT = 0
