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 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 1738-AENT/B
adapter for each module.
6. Enter 20 ms as the RPI for the 1738-IB4M12 module.
7. Click OK to save the configuration.
The digital input module appears in the I/O configuration folder indented
under Ethernet.
IMPORTANT To avoid overloading the 1738-AENT/B adapter, it is recommended
that the RPI be no less than 20 ms.
