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.
