Block variables and data types for FB501
Block variable Data type Comment
ADR_IN HW_IO Hardware ID of the module from which the data is to be read. The
hardware ID can be found in the properties of the module in the
device view or system constants (
PLC tags
→
Default tag table
→
System constants ).

DP-V0: Hardware ID of the module must be provided and
DPV_Mode flag should be False in FB500 block.

DP-V1 (or PROFINET): Hardware ID or 0 and DPV_Mode
flag must be True in FB500 block.
ADR_OUT HW_IO Hardware ID of the module to which the data is to be written. The
hardware ID can be found in the properties of the module in the
device view or system constants (
PLC tags
→
Default tag table
→
System constants ).

DP-V0: Hardware ID of the module must be provided and
DPV_Mode flag should be False in FB500 block.

DP-V1 (or PROFINET): Hardware ID or 0 and DPV_Mode
flag must be True in FB500 block
READ BOOL Read the parameter value 0
→ 1 (executed on positive edge).
WRITE BOOL Write the parameter value 0
→ 1 (executed on positive edge).
PARAM_NUM DINT Read/written parameter: 3 numbers = group, 2 numbers =
Index. For example, Par 20.06 = 2006.
VALUE_IN DINT Parameter value to be written.
DRIVE DB_ANY Instance Data Block. The drive variable is used for identifying to
which drive FB501
ACS_DRIVE_PARA belongs. The Instance
Data Block of FB500 ABB_DRIVE_CONTROL_FB must
correspond to the variable FB501 ACS_DRIVE_PARA.
THIS_BLOCK_DB DB_ANY Instance data block of FB501.
Note: POKE (FC1) and POKE_BLK (FC2) are used in FB501 block
logic to exchange data between FB500 and FB501.
DONE BOOL FALSE=Block execution not finished, TRUE=Block execution
finished.
ERR BOOL FALSE=No error, TRUE=Error occurred during block execution.
ERNO WORD Error code when ERR=TRUE.
BUSY BOOL FALSE=No operation active, TRUE=Operation active.
PARAM_NUM_OUT DINT Handled parameter number: 3 numbers = group, 2 numbers =
index; for example, Par 20.06 = 2006.
VALUE_OUT DINT Read parameter value.
