5069-ARM and 5069-FPD
Modules The following Compact 5000 I/O modules are available for unique purposes.
• 5069-ARM Address Reserve Module
• 5069-FPD Field Potential Distributor
5069-ARM Address Reserve Module
The 5069-ARM address reserve module reserves a node address in a
Compact 5000 I/O system. The module remains installed until you insert
another Compact 5000 I/O module into the same location.
For example, your application can require the use of a 5069-SERIAL module
in a specific node location. The module is typically installed when you install
the Compact 5000 I/O system. In this case, however, the required
5069-SERIAL module is not available for insertion.
To install Compact 5000 I/O modules, you attach them to left-most device in
the system. The node addresses increment as each module is installed. To make
sure that the 5069-SERIAL module is installed in the correct location later,
you install a 5069-ARM during initial system installation.
When the required Compact 5000 I/O module is available, you remove the
5069-ARM address reserve module and replace it with the 5069-SERIAL
module. Thus, you insert the module in the correct node address location.
Figure 4 shows a Compact 5000 I/O system that uses a 5069-ARM address
reserve module to reserve a node address.
