Chapter 4 Configure the Adapter for Direct Connection in RSLogix 5000 Software
5. Choose the Connection tab to set the RPI value.
RPI is selectable since it is a direct connection.
Note that the RPI is selectable on the screen and has a default value.
Because we are making a direct connection to each I/O module, we must
specify an RPI to determine how often the data is exchanged with the
1734-AENTR adapter for each module.
6. Enter 50 for requested packet interval (RPI) to set how often you exchange
data with the I/O adapters.
7. Click OK to save the configuration.
The relay output module appears under Ethernet.
IMPORTANT
To avoid overloading the I/O adapters, we recommend that RPI be no
less than 10 ms for rack connections and 50 ms for direct
connections.
