■Setting and link of the encoder for which Input Data Type is set to Pure binary or BCD
When data is input from the encoder for which Input Data Type is set to Pure binary or BCD, an error of 2 bits or more is
generated depending on the timing of reading data. Because of this, when data is input from the encoder for which Input Data
Type is set to Pure binary or BCD, specifying the read timing using a trigger signal for transfer timing is recommended.
To specify the read timing, follow the instructions below.
• Set "Data Length" to 11 bits or less.
• Link the terminal outputting the transfer timing signal to the "PRESET" terminal of the counter timer block.
Output
The following table shows the output of the parallel encoder block.

Variable name Data type Linkable block Output value Description
Output Word Multi function counter 0 to 4095 Inputs the value from the parallel encoder to the
"Absolute Encoder" terminal to use the value as a
preset value of the multi function counter.
