6-4 Troubleshooting the 1734-ADN(X) Adapter

Guidelines for Using

Your Adapter

Remember the following operational guidelines when using your

1734-ADN(X) adapter.

• 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 marker cards to identify your POINT I/O

modules. The cards are easily ordered from your Rockwell

Automation representative under the Bulletin 1492 number.

• Properly terminate the 1734-ADNX Subnet.

• Correctly set the Max Backplane MAC ID (1734-ADNX only).

Chapter Summary and

What’s Next

In this chapter you learned how to troubleshoot your adapter. Move

to Appendix A to see specifications for your adapter.

IMPORTANT

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

make sure you 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.
