Preface 6

• Do not leave spaces in the I/O. Instead, install all POINT I/O

modules adjacent to each other.

• Populate every position on the DIN rail.

• Do not add new I/O modules to the end of the POINT I/O

system while the system is under power.

• Use both labels with the I/O modules and removable terminal

blocks (RTBs).

• Do not separate I/O modules and RTBs with the same number.

• Do not move I/O modules to different locations on the DIN rail

after they have been installed and configured. You should

always place modules with the matching RTB.

• If adjacent modules (i.e., 2 or more) are removed, replace all of

them to operate the POINT I/O system. Input data will hold last

state until all previously-removed modules are replaced.

• Use Allen-Bradley terminal markers to identify your POINT I/O

modules. The cards are easily ordered from your Rockwell

Automation representative under the Bulletin 1492 number.

For more information on the Allen-Bradley terminal marking

kits, see the documents list on page

Preface-5.

Conventions Used In

This Manual

The following conventions are used throughout this manual:

• bullet lists (such as this one) provide information, not

procedural steps

• number lists provide sequential steps

• text written like this identify screen, menu, toolbar names, field

names, buttons, and check boxes on screens

• a menu item in this format File>Save identifies the submenu item

after the caret (>) accessed from the main menu (name before

the caret)

• pictures of symbols and/or screens represent the actual symbols

you see or the screens you use

IMPORTANT

If you must leave an I/O space open temporarily,

you must change the keying position on the

mounting base (1734-MB) to #5. This position will

prevent you from installing the wrong I/O module

on the base.
