(For PFC with software version SW 01.06 or lower):
PFC Output (I/O Assembly Instance 10):
Only the PFC output variables are transmitted via the corresponding input/output
communication link. The file length corresponds to the value in Class 100 /
Instance 1 / Attribute 101 (BK_FBOUT_ VAR_CNT).
PFC Input (I/O Assembly Instance 11):
Only the PFC input variables are transmitted via the corresponding input/output
communication link. The file length corresponds to the value in Class 100 /
Instance 1 / Attribute 100 (BK_FBIN_ VAR_CNT).
(For PFC software version SW 01.06 or higher):
PFC Output (I/O Assembly Instance 10):
Only the PFC output variables are transmitted via the corresponding input/output
communication link. The file length corresponds to the value in Class 100 /
Instance 1 / Attribute 104 (BK_FBOUT_ PLCONLY_VAR_CNT).
The first PFC byte to be transmitted is defined with the value in Class 100 /
Instance 1 / Attribute 105 (BK_FBOUT_STARTPLC_VAR_CNT).
PFC Input (I/O Assembly Instance 11):
Only the PFC input variables are transmitted via the corresponding input/output
communication link. The file length corresponds to the value in Class 100 /
Instance 1 / Attribute 102 (BK_FBINP_PLCONLY_ VAR_CNT).
The first PFC byte to be transmitted is defined with the value in Class 100 /
Instance 1 / Attribute 103 (BK_FBIN_STARTPLC_VAR_CNT).
