MICROLOGIX 1400'S
FTSE 8.2
I need to set a bit or change the value of a word so that I can read the tag in FTSE and cause the screen to change to the display that pertains to the alarm or event. I have this working now by having 16 rungs each with a NO contact, ONS and an OTE is series then 16 corresponding NO contacts in parallel to a bit that FTSE reads and makes the screen change. So to read one word B3:1 I have 35 rungs.
I would like to find a better way and have been trying by using B3:1 NEQ to 0 to trigger FTSE and also moving the value of it to another word and using that as a memory of B3:1 last value with a NEQ or GRT so I can also re-trigger the screen change on a second followup alarm or event if the first one has not restored yet. That part has not been working. If I use the NEQ then I get screen changes when alarms restore to normal also. If I use GRT the memory bit can be holding a higher value and not trigger at all if the next event/bit is a lower value than the previous alarm.
