PMAC2A-PC/104 Software Setup
26
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=$0
;BITS 9-16 are assigned as input
M40=$FFFF
;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 you must set I5=2 or 3 and ENABLE PLC 1
Thumbwheel Port Digital Inputs and Outputs
The inputs and outputs on the thumbwheel multiplexer port of either the ACC-1P or ACC-2P boards may
be used as discrete, non-multiplexed I/O. In this case these I/O lines can be accessed through M-variables
that are defined according to the setup of the address selection jumpers. Jumper E6 on the ACC-1P or E5
on the ACC-2P determine which set of the following M-variables are used:
ACC-1P with Jumper E6 in Position 1-2
