CompactLogix Analog Output Module 19

Rockwell Automation Publication 1769-IN089A-EN-P - March 2011

• PF = Analog power fail.

• S = General status (over-range, under-range, or open-circuit).

• D = Open-circuit diagnostics.

• H = Output held bit.

• U = Under-range (or low-clamp exceeded) alarm.

• O = Over-range (or high-clamp exceeded) alarm

Configuration Data File

The manipulation of the bits from this file is normally done with programming

software, such as RSLogix 500, RSNetWorx for DeviceNet software, during

initial configuration of the system. In that case, graphical screens are provided by

the programmer to simplify configuration. However, some devices, like the

1769-ADN DeviceNet adapter, also allow the bits to be altered as part of the

control program, using communication rungs. In that case, it is necessary to

understand the bit arrangement. The channel configuration words, the first two

words of each eight word group, are described on page 21

. Refer to the

CompactLogix I/O Analog Modules User Manual, publication 1769-UM002,

for additional details.

IMPORTANT

The output module’s input data file reflects the analog output data echo

of the module, not necessarily the electrical state of the output terminals.

It does not reflect shorted or open outputs.
