13.6.2 Table high speed comparison mode (M8130)
This section explains the table high speed comparison mode (high speed pattern output) of the DHSZ
instruction.
When two or more outputs should be activated at one time, use the HSCT instruction which can change up to
16 outputs.
1. Set data
Explanation of function and operation
1. 32-bit operation (DHSZ)
When the special auxiliary relay M8130 for declaring the table high speed comparison mode is specified as
in the DHSZ instruction, the special function shown below is provided.
Comparison table
1) Specify the head device number for the comparison table as .
Because one line in the comparison table uses four devices, × 4 devices are occupied from .
2) Specify the number of lines in the comparison table as .
The created table starts from the head register , and has the number of lines specified in .
3) Comparison data
Make sure that the comparison data is 32 bits.
Operand Type Description Data Type
Head word device number storing the data table (only data register D) 32-bit binary
Number of lines in the table (only K or H) … K1 to K128 or H1 to H80 32-bit binary
Device number of a high speed counter [C235 to C255] 32-bit binary
