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.
