Publication 1769-UM008A-EN-P - November 2001
Configuration Using the 1769-IF4XOF2 Combination Analog Module with a CompactLogix System C-9
Accessing the Input and
Output Tags Thin Profile
The analog input data file may be accessed by clicking the plus sign
to the left of the input tag, Local:1:I. Fault and status information for
the module can be found in this input tag. Refer to Chapter 5
concerning the 32-bit Fault value (Local:1:I.Fault). 4, pages 4-3
through 4-6 describe each value in the input file for the 1769-IF4XOF2
module.
The actual analog input data for this module can be found in the
following tags under Local:1:I.
•
Local:1:I.Ch0Data Data for input Channel 0
•
Local:1:I.Ch1Data Data for input Channel 1
•
Local:1:I.Ch2Data Data for input Channel 2
•
Local:1:I.Ch3Data Data for input Channel 3
The analog output data for the two analog output channels must be
written to the following tags under Local:1:O :
•
Local:1:O.Ch0Data Data for output Channel 0
•
Local:1:O.Ch1DataData for output Channel 1
