1769-OW8I Configuration File
The read/writable configuration data file allows the setup of the hold last state and
user-defined safe state conditions.
The manipulation of the bits from this file is normally done with programming
software (e.g. RSLogix 500, RSNetworx for DeviceNet, etc.) during initial
configuration of the system. In that case, graphical screens are provided via the
programmer to simplify configuration. However, some systems (e.g. 1769-ADN
DeviceNet Adapter) also allow the bits to be altered as part of the control program
using communication rungs. In that case, it is necessary to understand the bit
arrangment.
Program State Word
Word 1, the program state word, selects the hold
last state or user-defined safe state condition for
each individual output on a system transition
from Run to Program.
Program Value Word
The program value word, word 2, is used to
program the user-defined safe state value (0=Off,
1=On). Each output is individually configurable
for on or off.
Fault State Word
Word 3, the fault state word, selects the hold last
state or user-defined safe state condition for each
individual output on a system transition from Run
to Fault.
