I/O Variables Description

This table describes the input variables:

Inputs	Type	Comment
EXPERT_REF_IN	EXPERT_REF	Reference to the EXPERT function block. Must not be changed during block execution.
Execute	BOOL	On rising edge, starts the function block execution. On falling edge, resets the outputs of the function block when its execution terminates.

Inputs

Type

Comment

EXPERT_REF_IN

Reference to the EXPERT function block.

Must not be changed during block execution.

Execute

BOOL

On rising edge, starts the function block execution.

On falling edge, resets the outputs of the function block when its execution terminates.

This table describes the output variables:

Outputs	Type	Comment
EXPERT_REF_OUT	EXPERT_REF	Reference to the EXPERT function block.
Done	BOOL	TRUE = indicates that HSCDiag is valid. Function block execution is finished.
Busy	BOOL	TRUE = indicates that the function block execution is in progress.
Error	BOOL	TRUE = indicates that an error was detected. Function block execution is finished.
ErrID	EXPERT_ERR_TYPE	When Error is TRUE: type of the detected error.
EXPERTDiag	DWORD	When Done is TRUE: diagnostic value is valid, refer to the table below.

NOTE: For more information about Done, Busy and Execution pins, refer to General Information on Function Block Management.

This table indicates the diagnostic values:

Bit	HSC	Standard Encoder
0	Error detected on physical inputs
1	–	Error detected on physical outputs
2	–	–
3	–	–
4	–	Encoder power distribution feedback
5⁽¹⁾	–	Error detected on the transmission of the absolute SSI encoder frame
6⁽¹⁾	–	Indicates a parity error detected of the absolute SSI encoder frame
7	Invalid configuration detected
8	Invalid adjustment parameters detected
9	–	Encoder configuration in progress
10	–	–
11⁽¹⁾	–	Absolute SSI encoder status bit 0. Refer to your encoder user guide.
12⁽¹⁾	–	Absolute SSI encoder status bit 1. Refer to your encoder user guide.
13⁽¹⁾	–	Absolute SSI encoder status bit 2. Refer to your encoder user guide.
14⁽¹⁾	–	Absolute SSI encoder status bit 3. Refer to your encoder user guide.
15⁽¹⁾	–	–
(1) In case of a detected SSI error set the Enable condition to 0 to acknowledge the error condition.
