Troubleshoot the ArmorPoint DeviceNet Adapter 6-3

Guidelines for Using

Your Adapter

Remember the following operational guidelines when using your

ArmorPoint DeviceNet adapter.

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

I/O modules adjacent to each other.

• Populate every position on the mounting base.

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

system while the system is under power.

• Use labels with the I/O modules.

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

mounting base after they have been installed and configured.

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

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

last state until all previously removed modules are replaced.

• Use Allen-Bradley marker cards to identify your ArmorPoint I/O

modules. The cards are easily ordered from your Rockwell

Automation representative under the Bulletin 1492 number.

• Properly terminate the 1738-ADNX Subnet at the ends of the

Subnet trunk line.

• Correctly set the Max Backplane MACID (1738-ADNX only).
