Give a couple of screen shots showing
What you tried

Joe Hardane · Jan 25, 2013

well,

i have downloaded a sample for support.siemens, with a pdf file explaining the configuration.

here are the steps i did:
1- configure the counter in the HW config
2- downloaded SFB47 (count), loaded it is a FB, and got lost with the input output parameters:S

if i kind find a much simpler example or PDF file maybe, explainnig the parameter of the block more clearly.

thank you for ur help

What address did you put in LADDR?

If your HW is 768
A 16#300 goes in LADDR and If your wiring is correct - you should see a countval

the LADDR is correct, an i belve my wiring too.. i have 3 pulse encoder wired to chanel 0

i have tried to configure like the pic u sent( i just putted the LADDR and the rest of the parameter are not assigned) still, the countval is L#0

i even assigned 0 to the chanel input on the block, still same result

and how is the channel counter configured

These parameters?

Joe Hardane · Jan 25, 2013

it worked .

my problem was that iwas changing the output ( sw_gate) to true, not the input..didnt pay attention to that...

thank you for your help...
