Delta DVP-SS2 User Manual

3. Instruction Set
3-127
A. Normally, PLC only refreshes pulse output when the pulse instruction is executed. You can
use output pulse to check the pulse number but if the program is big, it may cause a bigger
different result in such a long scan.
B. When executing REF instruction with M1672-M1675, it can refresh the pulse output
immediately. And when REF instruction works with M1672-M1675 flags, it is only used to
refresh the pulse number not to refresh the actual inputs and outputs.
C. Refer to program example 5 for reference.
8. The function to update pulse number immediately is available for EC5: V1.00 and later.

REF X0 K8
Program Example 2:
When X0 = ON, the 4 output signals on Y0 ~ Y3 will be sent to output terminals immediately before
the program proceeds to END instruction.
