Re: [foxboro] Running Hours Counter

Gentlemen,
I want to thank all the people who supported me and helped me to build this 
running hours counter. I would like to share with you the techniques I learned.

I hope this will help others in the future:

Moore Method,
He proposed to use ACCUM block to be the counter with the following 
configuration:
PERIOD: 2 ; this is equivalent to 1 sec BPC
Adjust the time and use the built in RESET and SET functions

Martens Method,
The same proposal but with the following configuration:
PERIOD= 2 ; this is equivalent to 1 sec PBC
MEAS= Running Status (1,0)
MTRFAC= 0.0166666667 ; equivalent to 1/60 which means the value will change 
every one minute (60 sec)
PCNTOP= 2 ; Pulse rate per minute.
INITCL= 0 ;

Tarek Method,
Tarek proposed to use CALC block to build the counter as the following:
PERIOD= 2 ; this is equivalent to 1 sec BPC
BI01: MOTORRUN.CIN
BI02: RESET.CIN

CST
IN BI01
BIF 10
ADD RO01 1
OUT RO01
EXIT
10: IN BI02
11 BIT 13
12 EXIT
13CLR RO01
14EXIT

In addition to the other methods that use PI for the same propose.

Regards,
