Module-defined Data Types (1771-ACN15 and 1771-ACNR15 Adapters)
This table lists and describes module-defined data types for the 1771-ACN15 and 1771-ACNR15 Adapters. These tables include information for input as indicated by an "I" and output as indicated by an "O".
TIP:
The <input size 2*n+8> in this data type is the number of integers specified as the Input Size on the
General
Tab. For example, a setting of 8 results in a data type that is 24 bytes as shown in the AB:1771_ACN15_24Bytes:I:0 data type in the Controller Organizer
.Module-defined Data Type: AB:1771_ACN15_<input size 2*n+8>Bytes:I:0
<input size> is the number of integers specified as the Input Size on the General Tab
Name | Data Type | Default

RackStatus | DINT
DINT An atomic data type consisting of a DWORD used to store a 32-bit signed integer value (-2,147,483,648 to +2,147,483,647). | Binary | 0 = Good data 1 = Bad data |
InputGroupsValid | DINT | Binary | Bits 0-31 represent I/O groups 0-31. Bit value of 1 = discrete input module present in that I/O group. |
Data | INT[<input size>] | Binary | One 16-bit INT per I/O Group under the adapter for input data points. |
TIP:
The <output size 2*n+4> in this data type is the number of integers specified as the Output Size on the
General
Tab. For example, a setting of 8 results in a data type that is 20 bytes as shown in the AB:1771_ACN15_20Bytes:O:0 data type in the Controller Organizer
.Module-defined Data Type: AB:1771_ACN15_<output size 2*n+4>Bytes:O:0
<output size> is the number of integers specified as the Output Size on the General Tab
Name | Data Type | Default
Display Style | Definition |
Data | INT[<output size>] | Binary | One 16-bit INT per I/O Group under the adapter for output data points. |
