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, publicat
.
•
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 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-AENTR adapter for both
rack-optimized 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)
