Function
Multi-segment comparison is performed for cam control. The data table and counters used by comparison
are congured in incremental mode. This instruction is executed during the scan process of the main
program. The comparison result is affected by scan delay.
The complete ag M8029 is set to ON after comparison of n data entries is completed.
Example:
X10
〔INCD D100 C20 M0 K5 〕
S1 S2 D n
〔C20 K400〕
M8013
Assume that related variables are assigned values as follows. When X10 = ON, the execution result is
shown in the following gure.

Usage:
• Before the INCD instruction is executed, use the MOV instruction to assign values to variables of the related table.
• The comparison result is affected by the scan delay of the user program. The HSZ instruction for high-speed
comparison can be used for applications that require timely response.
