Does this do it ?


RI01 =3D CPLBUG_STA:STATION.DAY
RI01 =3D CPLBUG_STA:STATION.HOUR
RI01 =3D CPLBUG_STA:STATION.MINUTE

BO01 is the 1 minute pulse output
BO02 is the toggle output to the switch


STEP10 IN  RI01  ; DAY
STEP11 ADD RI02  ; DAY + HOUR
STEP12 ADD RI03  ; DAY + HOUR + MINUTE
STEP13 DEC       ; SUBTRACT 1
STEP14 BIT 22    ; BR IF <> 0 ; NOT OUR MINUTE

STEP15 IN  BO01  ; PULSE OUTPUT
STEP16 BIT 23    ; BR IF ALREADY SET
STEP17 SET BO01  ; ELSE, SET IT
STEP18 IN  BO02  ; LAST SWITCH TOGGLE
STEP19 NOT       ; TOGGLE SWITCH
STEP20 OUT BO02  ; SEND IT TO SWITCH
STEP21 GTO 23    ; AND EXIT

STEP22 CLR BO01  ; CLEAR PULSE WHEN NOT OUR MINUTE
STEP23 EXIT      ; ALL DONE, BYE

Subject: [foxboro] Calca Block Logic Help

Hi list,


I need some help with some calc block logic.....I think I'm having a
brain fart as I cannot get this.

What I want to do is use a calc block to set a bit (BO01) to 1 for one
minute at midnight on the first day of every month.  I've set RI01 =3D3D
Station.day, RI02 to Station.hour and RI03 to Station.Minute.  Then I
want to use this bit to toggle a SWCH block and hold it toggle for 1
month until the next 1st day at midnight comes and toggle the other way.
Here is what I have so far but I cannot get it to remember the toggle
bit so as to keep the SWCH Block Toggled

(1)In RI01
(2)SUB M01  (which is 1.0)
(3)MIN=3D20
(4)In RI02
(5)In RI03
(6)Add 3
(7)BIZ 9 (Set the Bit)
(8)GTO 11 (Clr the Bit)
(9)SET BO01
(10)EXIT
(11)CLR BO01

Then I was using a Flip Flop to remember this BO01 but I don't know how
to reset it when the next month comes around so that it will change the
toggle on the SWCH Block.  Any help would be much appreciated!
