Configure the Adapter for Direct Connection, Rack Optimization, and Enhanced Rack Optimization in RSLogix 5000 or Logix Designer Software Chapter 5
Access Module Data
Use the following information to use the I/O adapter data in the ladder logic
program:
• POINT_IO_Adapter — the name you gave to your EtherNet adapter
• # — slot number of POINT I/O module
• C — configuration, I = input, O = output
Use the controller tags in your ladder program to read input data or write output
data.
• For ControlLogix controller information, refer to ControlLogix System
User Manual, publication 1756-UM001
.
• Slot Status Bits: The Slot Status bits display the connection status for each
of the POINT I/O modules that use a rack-optimization connection.
– Bit 0 is reserved for the adapter and always reports a value of 1.
– Each of the other bits (1 to 63) correspond to a POINT I/O module
that you install in the POINT I/O backplane.
– In this example, we configured the 1734-AENT adapter for both rack-
optimization and direct connections.
The slot status bits indicate that we installed the module in slot 2 with it
operating correctly:
0 = module participating with no errors and
1 = module not participating or connection error (typically, module
removed/missing)
Chapter Summary
This chapter provided instructions on configuring an AENT Adapter for Direct
Connection, Rack-Optimization, and Enhanced Rack-Optimization in
RSLogix 5000 Software. It included information about hardware setup;
configuring the I/O Modules; adding an I/O adapter to the I/O configuration;
configuring for rack-optimization connections; configuring for direct
connections; and accessing module data.
