I am using Allen-Bradley plc with RSLogix 500 as ladder logic software. For forcing any Digital XIC/XIO (i.e, DI/DO) on any rung to ON/OFF, i have to use 'FORCE ON or FORCE OFF' function.
but when i check the Data table, i am able to change the state of that DI/DO by using 'TOGGLE BIT' functions also,as i do for forcing any 'BIT (eg-B9:0/1)'ON/OFF. if i FORCE ON any D/O and then change it's binary state by using TOGGLE BIT,what will be the effect on my actual output.
can some one clear me about what's the difference in using 'TOGGLE BIT' and 'FORCE ON/OFF'function.
