Placing and Configuring Local I/O 3-9

disconnected from the system bus while under power. All outputs turn off

when the system bus or any module faults.

RSLogix 5000 software creates tags for modules when you add them to the

I/O configuration. The 1769 module tags define configuration (C) data type

members which may include attributes for alternate outputs.

DriveLogix5730 does not enable local modules to use the alternate outputs.

Do not configure the attributes listed below:

Any 1769 Compact I/O modules used as remote I/O modules in a

DriveLogix5730 system do support the Hold Last State and User-Defined

Safe State features.

Inhibiting I/O Module Operation

In some situations, such as when initially commissioning a system, it is

useful to disable portions of a control system and enable them as you wire

up the control system. The controller lets you inhibit individual modules or

groups of modules, which prevents the controller from trying to

communicate with these modules. Inhibiting a module shuts down the

connection from the controller to that module.

When you create an I/O module, it defaults to being not inhibited. You can

change an individual module’s properties to inhibit a module.

For digital output modules: For analog output modules:

• ProgToFaultEn

• ProgMode

• ProgValue

• FaultMode

• FaultValue

• CHxProgToFaultEn

• CHxProgMode

• CHxFaultMode

• where CHx = the channel number

ATTENTION: Inhibiting a module causes the connection to the

module to be broken and prevents communication of I/O data.

The controller and other I/O modules continue to operate based

on old data from that module. To avoid potential injury and

damage to machinery, make sure this does not create unsafe

operation.
