| ManualMode is an input which is used to disable the Excel 10s control algorithms |
|
|
| MODE_DISABLE | 1 |
|
|
|
|
|
| and to manually set the physical outputs. ManualMode remains unchanged until |
|
|
| MODE_MANUAL | 2 |
|
|
|
|
|
| another mode has been commanded or an application restart has been performed. |

| See the Data1.mode for more details.The valid enumerated values are: |
|
|
| UNSUPPRESS_ALARMS | 4 |
|
|
|
|
|
| MODE_ENABLE enables the node so that the control algorithm determines the |
|
|
|
|
|
|
|
|
|
|
| operating mode, and controls the physical outputs. MODE_ENABLE is the default |
|
|
|
|
|
|
|
|
|
|
| state after power restore or application restart. If the mode was MANUAL and |
|
|
|
|
|
|
|
|
|
|
| nviManualMode is set to MODE_ENABLE, the node then goes through |
|
|
|
|
|
|
|
|
|
|
| application_restart.MODE_DISABLE sets the node to the DISABLED_MODE. The |
|
|
|
|
|
|
|
|
|
|
| alarm NODE_DISABLED is initiated, all control loops are disabled, and the physical |
|
|
|
|
|
|
|
|
|
|
| outputs are turned off. The physical inputs, network variable inputs, and network |
|
|
|
|
|
|
|
|
|
|
| variable outputs are still functioning when the node is in the DISABLED_MODE. |
|
|
|
|
|
|
|
|
|
|
| MODE_MANUAL sets the node into the MANUAL mode. If MANUAL is selected, the |
|
|
|
|
|
|
|
|
|
|
| controller enters Test Mode (manual override of outputs). The alarm |
|
|
|
|
|
|
|
|
|
|
| NODE_DISABLED is initiated, all control loops are disabled, and the physical |
|
|
|
|
|
|
|
|
|
|
| outputs are controlled manually as commanded by nviManValue. The nodes |
|
|
|
|
|
|
|
|
|
|
| configuration variables and nviManValue are used to set valves, dampers, and / or |
|
|
|
|
|
|
|
|
|
|
| digital output to the desired manual positions or state(s). The physical inputs, |
|
|
|
|
|
|
|
|
|
|
| network variable inputs, and network variable outputs are still functioning when the |
|
|
|
|
|
|
|
|
|
|
| node is in the MANUAL mode.SUPPRESS_ALARMS causes nvoAlarm.type to be |
|
|
|
|
|
|
|
|
|
|
| set to ALARM_NOTIFY_DISABLED, and AlarmLog to no longer record alarms. If |
|
|
|
|
|
|
|
|
|
|
| alarms are suppressed, UNSUPPRESS_ALARMS causes Alarm.type and |
|
|
|
|
|
|
|
|
|
|
| AlarmLog to be returned to reporting alarms. See Alarm for more details. All |
|
|
|
