Connection View

Use Connection to define controller-to-device behavior:
  • Set the RPI rate. For more information, see Requested Packet Interval.
  • Select Unicast or Multicast connection to use on the EtherNet/IP network. For more information, see Unicast or Multicast Connection.
  • View the reason of Connection Fault.
    TIP: If there is a connection fault, Connection Fault area displays the error code with description that helps you to troubleshoot the module. For more information, see Troubleshoot Your Module.
  • Inhibit the module. For more information, see Module Inhibiting.
  • Configure fault response for connection failure while the controller is in Run Mode.
  • Enable or disable the Automatic Diagnostics.
    ATTENTION: If you do not enable Automatic Diagnostics, the device does not publish diagnostics to FactoryTalk Alarms and Events.

Recommended Minimum RPI Values for Notch Filters

In the following table, each Notch Filter setting has two recommended minimum module RPI values that allow the required time to collect samples from each channel. One setting provides faster sample speed and the other provides slightly better resolution at slower sample speeds.

Minimum RPI Calculation When Using Different Notch Filter Selections

When input channels on the same module use different Notch Filter selections, you must consider the sample time for each channel. This helps you to find the recommended RPI that provides enough time for sampling all channels.
The eight input channels on the module are grouped into two groups. Channels 00…03 are grouped, and channels 04…07 are grouped. When you determine the recommended minimum module RPI value, remember:
  • The recommended minimum module RPI value when channels use different Notch Filter selections is determined by group.
    The recommended minimum RPI rates for all enabled channels added together. If any channel in the other group is enabled, the recommended minimum RPI rate for each enabled channel is increased by 0.2 ms.
  • If the groups have different recommended minimum RPI values, use the higher RPI value when you configure the module.
