7 APPLICATION INSTRUCTION
7.15 Drum sequence
Relative method
INCD
This instruction creates many output patterns using a pair of counters.
Setting data

Descriptions, ranges, and data types
■
Applicable devices
*1
Only C can be used.
*2
T, ST, C cannot be used.
Processing details
• The current value of a counter is compared with the data table having "n" lines starting from (s1) (which occupies "n" lines
1 device). When the value is equivalent to the table data, the current output is reset, and the next output is controlled. In this
way, the ON/OFF status of specified outputs is controlled in turn.
■
Operation example
• The following ladder example shows the operation. (s2) occupies two points. In the following timing chart, C0 and C1
correspond to the two points.
• Suppose that the following data is written in advance by a transfer instruction:
