c. From the Connection pull-down menu, choose the appropriate
connection for the 1734 Ethernet adapter.
d. From the Chassis Size pull-down menu, choose the number of
POINT I/O modules that will be attached to the 1734 Ethernet
adapter plus 1 for the 1734 Ethernet adapter.

Add and Configure Safety
Digital Input Modules To include a safety digital input module in the project, you add the module under
the I/O chassis in the I/O Configuration tree, configure the module’s general
properties, configure the digital inputs, and then configure test outputs as
described in the following sections.
Add the Safety Digital Input Module
Follow these steps to add the POINT Guard I/O safety digital input module.
Choose Description
Listen Only Read or verify standard digital I/O data only, but does not control the modules.
(When you have multiple controllers, one controller is used to control and the other
controllers are used to monitor.)
None The adapter makes a direct connection to each of the module’s listed under the
1734-AENT adapter in the I/O Configuration tree.
Rack
Optimization Standard digital I/O data is collected into a single rack image.
POINT specialty, analog, or safety (POINT Guard I/O) modules do not use
rack optimization.
TIP If there are no standard digital I/O modules in your POINT I/O
system, choose None.
IMPORTANT Do not count terminal bases. Enter only the number of physical modules
installed, plus 1 for the adapter. This number must match exactly. You cannot
enter a higher number anticipating future expansion.
Each POINT Guard module you configure may consume up to 2 connections of
the 20 connection limit within the 1734-AENT or 1734-AENTR modules. Be
sure you are aware of and design your POINT system with these limits in mind.
