Compact 5000 I/O Serial Module Operation
5069-ARM Address
Reserve Module
Every Compact 5000 I/O module has a unique node address in a system. As
modules are installed, the node addresses increment. The Logix Designer
application project includes modules in the I/O Configuration that correspond
to the physical modules.
If a module is not available during initial system installation and operation, you
can use a 5069-ARM address reserve module to reserve the slot in the system.
That is, you install the 5069-ARM address reserve module to reserve the node
address. The address reserve module remains installed until the I/O module is
available.
When you install the address reserve module, you also make sure that the
subsequently-installed modules are at the correct node address.
You use the corresponding entry in the Logix Designer application project to
reserve the node address. That is, when you add modules to the I/O
Configuration tree in the project, you add an address reserve module at the node
address that matches the physical module location.
