HIGH-SPEED COUNTER INSTRUCTION
14.1
High-speed Processing Instruction
Setting 32-bit data comparison
DHSCS
This instruction compares the value counted by a high-speed counter with a specified value, and immediately sets a bit device
if the two values are equivalent to each other. The high-speed pulse input/output module is not supported.
*1 When the interrupt pointer (I) is specified in operand (d) by ST language and the FBD/LD language, use the DHSCS_I instruction.
Setting data
■
Descriptions, ranges, and data types
*1 In the case of the ST language and the FBD/LD language, d displays as Pn.
■
Applicable devices
*1 Enable the FX3 compatible function, and specify a device between LC35 and 55 that is designated as an FX3 compatible high-speed
counter. For FX3 compatible function, refer to
MELSEC iQ-F FX5 User's Manual (Application).
*2 I16 to I23 can be used.
