•
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, publicat
,
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.
