Place additional rungs here to transfer more blocks at a time. You can have
up to 16 rungs total when using a PLC-5/15 or PLC-5/25 processor. You
can have up to 64 rungs total when using a PLC-5/20, -5/30, -5/40, -5/60,
or -5/80 processor. The number of rungs you have here must equal the
number of rung pairs you have in file 10.
Rung 9:5
THE USER WILL ADD MANY SIMILIAR RUNGS THAT MOVE DATA IN N33 TO THE PROPER
ADDRESS IN MEMORY.THE DATA IN N33:25 CAME FROM THE PRIMARY PROCESSOR WORD
N34:25. IN THE PRIMARY PROCESSOR’S PRIMARY SUBROUTINE THERE IS A SIMILIAR RUNG
THAT MOVES C5:0.ACC TO N34:25. RUNGS LIKE THESE SHOULD BE ADDED FOR ALL DATA
TABLE VALUES THAT NEED TO BE SENT.
