reference,when the value it continues to count is equal to PV,it will execute “CV=PV”
interrupt.For example,if it sets 3 PV values,such as 10,1000 and 1000,and the current counting
value is 100 before HSC starts,then when the counting value reaches 110,1110 and 2110,it will
execute corresponding“CV=PV” interrupt.

“CV=PV”interrupt cyclic execution
“CV=PV”interrupt cyclic execution is only valid when PV is set as relative value.
If SM141.0 is 0,it means “CV=PV” interrupt only executes once.When all interrupts finish
execution,then it will stop.If it needs to execute again, it must modify the related registers and
execute HSC instruction again.
If SM141.0 is 1,it means “CV=PV” interrupt is cyclic execution.When the last PV interrupt
finishes execution,PLC will take the current counting value as reference to calculate new value
for PV interrupt,then it will start to compare the counting value and execute “CV=PV”
interrupt and so forth.This process will execute cyclically.
For example,it sets 3 PV values,such as 10,1000 and 1000.And the current counting value is
100 before HSC starts,then the value for every interrupt is as following table.
Current
counting value Interrupt times First value Second value Third value
100 1st time 110 1110 2110
2110 2nd time 2120 3120 4120
4120 3rd time 4130 5130 6130

3.2.3.4 “CV=PV” Envent No.
When it uses single PV mode, the HSC will be fully compatible with K5 (Include “CP=PV”
event No.).
When it uses multiple PV mode, the HSC will assign a new event No. for 32 PV, as shown in
following table.
