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!
