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!
