Attributes:
| Name | Description |
|---|---|
| ProportionalScalar: DevDouble | P parameter |
| IntegralScalar: DevDouble | I parameter |
| DifferentialScalar: DevDouble | D parameter |
| LoopTimeScalar: DevDouble | Cicle time for the control loop. |
| StartOutputValueScalar: DevDouble | Start value for the output. |
| InputValueScalar: DevDouble | Value readout from the input device or calculated from values from the input device |
| OutputValueScalar: DevDouble | Value calculated by the PID controller and sent to the output device |
| OutputLimitScalar: DevDouble | Limit for the output value. |
Commands:
| Name | Description |
|---|---|
| StateInput: DevVoid Output: State Device state |
This command gets the device state (stored in its device_state data member) and returns it to the caller. |
| StatusInput: DevVoid Output: ConstDevString Device status |
This command gets the device status (stored in its device_status data member) and returns it to the caller. |
| StartCtrlLoopInput: DevVoid Output: DevVoid |
Start control loop |
| StopCtrlLoopInput: DevVoid Output: DevVoid |
Stop control loop |
Pipes:
Properties:
| Name | Description |
|---|---|
| InputDSDevString | Device Server where the input parameters are read from |
| OutputDSDevString | Device Server where the output parameter is write to |
| InputValueLogicDevString | String describing what to read from the input device and possible operations: 0 -> read value 1 -> difference of average values Format, ex. 0,AttrIbuteName (read attribute AttributeName from InputDS and used as input value) 1,Attr1,Attr2,Attr3,Attr4 (read Attr1 ,Attr2 ,Attr3 and Attr4 form InputDS and use (Attr1+Attr) - (Attr3+Attr4) as input value More logics can be implemented. |
| OutputAttributeDevString | Name of the attribute for writing the pid computed value. |
