3.2.9 ENCODER (SMC_Encoder)
The control configuration serves to implement and configure encoders into an axis group.
The created data structure of SMC_Encoder_REF type must be processed by an instance of
the SMC_ENCODER POU. This outputs an AXIS_REF data structure which can serve as input
for all other function blocks (e.g. MC_CamIn, MC_GearIn, MC_TouchProbe) as soon as the
bValid output confirms the validity of the data.
Inputs/outputs (VAR_IN_OUT)
encref: SMC_Encoder_REF: VAR_IN_OUT
Pointer to the operating data of the encoder.
Inputs (VAR_INPUT)
dwEncoderValue: DWORD
Actual value of the encoder
bSet: BOOL
Set the value at the EncoderValue input to the SetValue input.
fSetValue: DWORD
Position value to be accepted.
Outputs (VAR_OUTPUT)
bValid: BOOL
TRUE indicates that the data is valid.
bError : BOOL
TRUE indicates that an error has occurred in the function block.
nErrorID: INT
Error number
Axis : AXIS_REF
The POU writes the correspondingly scaled position data of the encoder axis into this axis
data structure.
