Moving an interger into Control R6

[vanilla_gorilla 0]

If I move an integer (in this case #1) into R6:0.POS does it increment the count in .POS or does it jusr mov a 1 in each time and R6:0.POS stays at 1 ?? BST XIC R6:0/DN NXB XIO I:1.0/9 BND XIC I:1.0/11 MOV 1 R6:0.POS

There is no problem in moving an integer into R6:0.pos. I do it often with sequencers. HOWEVER, many instructions that use the R data files only work operate on false->true rung transtiions. For example, if the R6:0 structure is a control structure for a sequencer and you move a 3 into R6:0.pos the sequencer output word will not be automatically updated - you need to manually update it.

Just curious what is R6.0.LEN in your application. Your program will move 1 into R6.0.pos for each I:1.0/9 while I:1.0/11 is true and when R6.0/DN is true.

R6.LEN is 9 referenced in SQC BST XIC I:1.0/11 NXB XIC I:1.0/13 BND XIO B3:0/10 BST SQC #N7:0 N7:20 I:1.0 R6:0 9 1 NXB CTU C5:5 9 3 BND

To answer your original question the rung you posted. BST XIC R6:0/DN NXB XIO I:1.0/9 BND XIC I:1.0/11 MOV 1 R6:0.POS Does the following: 1. Check if the R6.0 control register pos pointer has reached position 9 {is done}. 2. Check to see if input I:1.0/9 is off. {probably a sequence reset signal} 3. Check to see if input I;1.0/11 is on. {probably a use sequencer signal flag}. 4. If {condition 1 or condition 2} and condition 3 is true tne load a 1 into the R6.0.pos register. It does not increment R6.0.pos.
