Chapter 3 I/O Memory Mapping
Module Configuration Word
Word 6 of the configuration data file contains the Enable/Disable Cyclic
Calibration bit as shown in the table below.
1769-IT6
The following I/O memory mapping lets you configure the 1769-IT6 module.
Input Data File
The input data file contains the analog values of the inputs.
The bits are defined as follows:
• Sx = General status bit for channels 0…5 and CJC sensors (S6 and S7).
This bit is set (1) when an error (over-range, under-range, open-circuit, or
input data not valid) exists for that channel. An ‘input data not valid’
condition is determined by the user program. This condition occurs when
the first analog-to-digital conversion is still in progress, and after a new
configuration has been sent to the module. Refer to the Compact I/O
Thermocouple/mV Input Module User Manual, publication 1769-
UM004 for additional details.
