Chapter 3
Auto-addressing with a
1734-PDN Adapter and
POINT Guard I/O Modules
Sequential auto-addressing is where the leftmost node address is configured and a
parameter is set in that module that automatically addresses nodes to the right of
the module. The leftmost node can be a POINT Guard I/O module or a
standard POINT I/O module.
Follow these steps to use the auto-address feature.
1. Reset any modules that you are not sure are out-of-box.
2.
Attach the first module to the 1734-PDN adapter.
3. Use the node commissioning tool to set the node address of this module.
4.
Attach the additional nodes to the right of the module used in
steps
2 and 3 .
5.
Perform the auto-address feature on the module used in steps 2 and 3 .
A. Set the address of the leftmost I/O module.
B. When you configure the leftmost module, set Sequential
AutoAddress to ‘Sequential Address’.
The module sequences the rest
of the modules to its right in
the group.
