1769-OW8 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.
