AUTOMATE_ENCODER( )
Automate_Encoder() allows processing of low bandwidth Sin/Cos signals for use in VCL. is
function runs in the 4 ms queue.
Syntax:
Automate_Encoder(ENC#, @ChannelA, @ChannelB, V_
Min_A, V_Max_A, V_Min_B, V_Max_B, Encoder_Type)
Parameters:
ENC# ENC1 or ENC2 (Holds the ID of the desired encoder block).
@ChannelA Pointer to source variable 1 (–32767 – 32767).
@ChannelB Pointer to source variable 2 (–32767 – 32767).
V_Min_A Minimum Voltage of encoder channel A (–32767 – 32767).
V_Max_A Maximum Voltage of encoder channel A (–32767 – 32767).
V_Min_B Minimum Voltage of encoder channel B (–32767 – 32767).
V_Max_B Maximum Voltage of encoder channel B (–32767 – 32767).
Encoder_Type Only Sin/Cos encoders are supported, this should be set to 0.
Returns:
0 Function did not successfully execute.
1 Function successfully executed.
Error Codes:
BAD_ID
ENC# out of Range.
PT_RANGE
Invalid source or destination parameter.
The outputs of these functions are as follows:
ENC1_rev_output – ENC1’s output in revolutions
(–32767 – 32767)
ENC1_Angle – ENC1’s output angle in degrees (0 – 4096 = 0 –
360 degrees)
ENC2_rev_output – ENC2’s output in revolutions
(–32767 – 32767)
ENC2_Angle – ENC2’s output angle in degrees (0 – 4096 = 0 –
360 degrees)
Example:
Return = Automate_Encoder(ENC#, @ChannelA, @
ChannelB, V_Min_A, V_Max_A, V_Min_B, V_Max_B,
Encoder_Type)
