Access Module Data Via The 1734-Aent Adapter - Allen-Bradley Rockwell Automation 1734-AENT User Manua

5-16 Configure the 1734-AENT for Direct Connection and Rack Optimization in RSLogix 5000
Access Module Data via
the 1734-AENT Adapter
Publication 1734-UM011A-EN-P - February 2004
Use the following information to use the 1734 POINT I/O Ethernet adapter
module 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 RSLogix 5000 programming instructions, refer to RSLogix 5000
Getting Results, publication no. 9399-RLD300GR.
• For ControlLogix controller information, refer to ControlLogix System
User Manual, publication no. 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 optimized connection.
Bit 0 is reserved for the adapter and always reports a value of 1. Each of
the other bits (1-63) correspond to a POINT I/O module that may be
installed in the POINT I/O backplane. Note that in this example, the
1734-AENT is configured for both rack optimized and direct
connections. The slot status bits indicate that the module in slot 2 is
installed and operating correctly (0=module participating with no errors
and 1=module not participating or connection error (typically, module
removed/missing)).
This value indicates that slot 2 is
the only module participating in
the rack optimized connection
with no errors.
