A.5 Control Request Return Codes
When processing a disable communications output request, the DCA may not be able to execute
the request. If this occurs, the DCA will set the status code returned with the request to the
appropriate error code, and negatively acknowledge (NACK) the control request. This section
describes the possible status codes returned.
Control Already Active (0x0002)
The control point is already in the requested state. Refer to the Allen-Bradley ANSI X3.28 DCA
Functional Specification for more information on whether controls latch on or off, or toggle.
Illegal Point Number (0x0003)
There is no function associated with this output point. Refer to the Allen-Bradley ANSI X3.28
DCA Functional Specification for more information on the number of digital output points
required by the DCA and each point's associated functionality.
Command Transmission Failed (0x0080)
The DCA was unable to successfully transmit the command to the associated controller due to
poor communications.
Invalid Control Type (0x0081)
The control point selected does not support the requested control type.
Value Out of Range (0x0082)
For setpoints, the requested setpoint value is outside the allowable range.
For R/L controls, the multiplier is too large.
Point Off-Line (0x0083)
The control was not attempted because the selected control point is currently off-line.
