Configuration Files
The following configuration information applies to these modules:
The read/writable configuration data file allows the setup of the hold
last state and user-defined 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 arrangement.

Program State Word (word 1) selects the hold last state or user-defined safe state condition on a
system transition from Run to Program. User-Defined Safe State = Bit Setting 0 and Hold Last State
= Bit Setting 1
2
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.
3
Fault State Word (word 3) selects the hold last state or user-defined safe state condition on a
system transition from Run to Fault. User-Defined Safe State = Bit Setting 0 and Hold Last State
= Bit Setting 1
4
Fault Value Word (word 4) is used to program the fault state value (0 = Off, 1 = On). Each output is
individually configurable for on or off. Off = Bit Setting 0 and On = Bit Setting 1
