Software Setup

In order to properly setup the digital outputs an initialization PLC must be written scanning through once
on power-up/reset, then disabling itself:

OPEN PLC1 CLEAR
M32=$FF

;BITS 0-8 are assigned as output

M34=$0

;BITS 9-16 are assigned as input

M40=$FF00

;Define inputs and outputs voltages

M42=$FFFF

;All lines are I/O type

DIS PLC1

;Disable PLC1 (scanning through once on

;power-up/reset)
CLOSE

Note:

After loading this program, set I5=2 or 3 and ENABLE PLC 1.
