Chapter 3 I/O Memory Mapping
Program to Fault Enable Bit (PFE)
Word 0, bit 0, allows the selection of which data value, the program or fault value,
to apply to the output if a system in Program mode undergoes a system fault,
resulting a change to Fault mode.
Module Default Condition
The modules default condition is all zeros, programming the conditions shown
below.
1769-IR6
The following I/O memory mapping lets you configure the 1769-IR6 module.
Input Data File
The first six words (0…5) of the input data file contain the analog RTD or
resistance values of the inputs. Words 6 and 7 provide sensor/channel status
feedback for use in your control program as shown below.
