APPENDIX C C.3 POINT LISTS

C.3.3 BINARY OUTPUT, CONTROL RELAY OUTPUT BLOCK
The LPS-D uses the following rules when parsing requests for control of Binary Output points using Object 12.
1. The Count field is checked first. If it is zero, the command will be accepted but no action will be taken. If
this field is non-zero, the command will be executed once.
2. The Control Code field of Object 12 is then checked:
• The Queue and Clear sub-field are ignored.
• For all points, the only valid control is “Close – Pulse On” (0x41). This is used to initiate the function
associated with the point.
• Any value in the Control Code field not specified above is invalid and will be rejected.
3. The On Time and Off Time fields are ignored. A “Pulse On” control takes effect immediately when received.
Thus, the timing is irrelevant.
4. The Status field in the response will reflect the success or failure of the control attempt as below:
• A Status of “Request Accepted” (0) will be returned if the command was accepted.
• A Status of “Request Not Accepted due to Formatting Errors” (3) will be returned if the Control Code
field was incorrectly formatted or an invalid code was present in the command.
• A Status of “Control Operation not Supported for this Point” (4) will be returned if an attempt was
made to operate the point and the device, owing to its configuration, does not allow the point to per-
form its function.
