The bits are defined as follows:
•
SGN = Sign bit in 2’s complement format.
•
Nu = Not Used. Bit set to 0.
•
S x = General Status bit for input channels 0…15.
•
O x = Over range flag bits for input channels 0…15.
•
U x = Under range flag bits for input channels 0…15.
•
H x = High Alarm flag bits for input channels 0…15.
•
L x = Low Alarm flag bits for input channels 0…15.
Configuration Data File
The manipulation of bits from this file is normally done with programming software
(for example, RSLogix 5000, RSLogix 500, or RSNetWorx for DeviceNet software)
during initial configuration of the system. In that case, graphical screens provided
by the programming software simplify configuration.
Some systems, like the 1769-ADN DeviceNet adapter system, 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.
