What gets mapped
I/O Data
APACS IOBUS discrete inputs and outputs are mapped to the input data on ControlLogix
connections from 0 upwards, as required. Discrete input and output data points consist of
a byte of data and are mapped to SINT data in the ControlLogix. The low bit in each
SINT corresponds to the value of the point (0 or 1, False or True).
APACS IOBUS analog inputs and outputs are mapped to the input data on ControlLogix
connections from 8 downward, as required. Analog inputs and outputs are mapped to
REAL data in the ControlLogix.
In addition, each discrete output, analog input and analog output has an associated status
byte. These are also mapped to SINT input data in the ControlLogix, in connections 0
and up.
Diagnostic Counters
QTS-CLX-APACS diagnostic counters are integers are mapped to ControlLogix input
data of type INT on connection 9.
Alias Name Offset Description
StatRxGood 0 Good packets received from the network
StatAbortErr 1 Bad packets, abort errors
