PULSE Counter, without counter logic

Ganeshan

Hi Friends,

I have a challenge in increamenting a integer variable,

MW10 MW20 PULSE MW20

------------------------------------------------------------------------------------------------

0 0 1 1

0 1 1 2

0 2 1 3

100 100 1 101

100 101 1 102

200 200 1 201

200 201 1 202

AND SO ON......

it means, MW20 should be startt count from the MW10's last valuve

for this, we made a counter, which is having a limitation of "999" as preset value, now we changed into addition logic, please find the existing and new proposed logic in the attachment.

how can we resolve this, any ideas?

yes william, you got my point,

there is two way

1. i need a counter like S_CU with maximum count of 3000 or something, S, PV

(I seen a counter SFB0, which can count upto 32767, but, this doen't have a 'S', Set, so that i can force the value)

2. as you said, we need to know the bit, when the MW30 value change event, when value change, then, we can force the value into some other location (lets say MW32). we can start count from MW32.

the reason is, FC is forcing the value continuously, so we can not move further to increament.
