Configure the Controller Application Chapter 1
3. Type the Ethernet address for the module in the chassis.
4. Click OK.
5. Repeat step 1 through step 4 to configure each network adapter in the local chassis of the target controller.
Configure I/O Modules
Follow these steps to configure local analog and digital I/O modules with a Requested Packet Interval (RPI) and module
definition, if applicable. The RPI is the amount of elapsed time for an exchange of data between the controller
and module.
1. In the Controller Organizer, double-click the I/O module to be configured.
2. On the Module Properties dialog box, click the Connection tab.
3. Set the RPI and click OK.
For certain device types, there can be additional configuration required. For example, when using a HART module,
you have to change the module definition to collect HART data.
4. Follow these steps to modify the module definition:
a. On the New Module dialog box, click Change in the Module Definition area.
b. From the Input Data pull-down menu, choose from the list.
For example, Analog and HART by Channel.
c. Click OK.
d. Click Yes if a warning message appears that you are changing the module definition.
IMPORTANT An RPI that is set too fast can affect controller performance. We suggest that you specify an RPI that is two times faster
than task execution or based on inherent properties of the signal being measured. For example, a 250 ms task requires a
125 ms time, but temperature measurements can be set slower as they are unlikely to change that quickly.
