Data Link Confirm Mode
Data Link Confirm Mode : Never #DL confirm mode (N=Never, S=Sometimes, A=Always)
IED can request acknowledgement from master station when sending data. The
codes are as follows: 0=Never, 1=Sometimes, 2=Always.
Data Link Confirm Tout
Data Link Confirm Tout : 1000 #1-65535 milliseconds DL confirm timeout
Time period to wait for Master Data Link confirmation of last frame sent. This
time is in milliseconds. This parameter is only used if the frame is sent with
confirmation requested.
Data Link Max Retry
Data Link Max Retry : 2 #0-255 maximum DL confirm retry count
Maximum number of retries at the Data Link level to obtain a confirmation. If this
value is set to 0, retries are disabled at the data link level of the protocol. This
parameter is only used if the frame is sent with confirmation requested.
App Layer Confirm Tout
App Layer Confirm Tout : 2000 #1-65535 milliseconds App Layer confirm timeout
Event data contained in the last response may be sent again if not confirmed
within the millisecond time period set. If application layer confirms are used with
data link confirms, ensure that the application layer confirm timeout is set long
enough.
Unsolicited Response
Unsolicited Response : No #Generate Unsolicited responses (Yes or No)
Set if the slave unit will send unsolicited response messages. If set to No, the
slave will not send unsolicited responses. If set to Yes, the slave will send
unsolicited responses. The module will send the event when one of the following
conditions are satisfied:
1 Minimum number of events is reached
2 Delay time is reached
Class 1 Unsol Resp Min
Class 1 Unsol Resp Min : 10 #1-255 min number of events before send
Minimum number of events in Class 1 required before an unsolicited response
will be generated.
Class 2 Unsol Resp Min
Class 2 Unsol Resp Min : 10 #1-255 min number of events before send
Minimum number of events in Class 2 required before an unsolicited response
will be generated.
