Control Operations
The control operations include operation like Operate, Select, Cancel. These are typically
used for IED controls. The ECM850 supports the command 'direct operate' and 'select
before operate' (SBO) in normal and in enhanced security.
In operation-"Operate", the ECM850 automatically checks the actual Control Model and
executes the command in the corresponding way.
Commands and Control Models
For this, first attribute †/ctlModel[CF] of the Data Object is read out internally by ECM850
and depending on the value of this attribute, the corresponding command is executed using
the respective Control model:
•
System Operation
Dev.DevF650.auxPTOV2/PTOVEna/setVal[SP]
S8_Dev_DevF650.auxPTOV2_PTOVEna.setVal_SP.WRITEVal
S8_Dev_DevF650.auxPTOV2_PTOVEna.setVal_SP.WRITECmd
S8_Dev_DevF650.auxPTOV2_PTOVEna.setVal_SP.WRITERslt
S8_Dev_DevF650.auxPTOV2_PTOVEna.setVal_SP.ReadVal
Step1: Write value to be written to device in the PPV with extension (†.WRITEVal).
e.g. S8_Dev_DevF650.auxPTOV2_PTOVEna.setVal_SP.WRITEVal
Step2: Issue a transition from "0" to "1" in the PPV with extension (†.WRITECmd) to
trigger the transfer of written value in step#1 to the IED.
e.g. S8_Dev_DevF650.auxPTOV2_PTOVEna.setVal_SP.WRITECmd
Step3: Check the PPV with extension (†.WRITERslt) for success (1).
e.g. S8_Dev_DevF650.auxPTOV2_PTOVEna.setVal_SP.WRITERslt
[WRITERslt returns code:
0: BUSY
1: DONE
2: ERROR ]
Step4: Check that the written value has been updated in device by reading the PPV
with extension (†.ReadVal)
e.g. S8_Dev_DevF650.auxPTOV2_PTOVEna.setVal_SP.ReadVal
Value 0: no action, execute command not possible (status only)
