Relay operation control
Opening:
EnaOpn = true
EnaCls = false
1 is written to ctlSelOn
Then, stSeld goes from false to true
Finally we write the value of 1 to ctlOperOn and the opening relay
Closing:
EnaOpn = false
EnaCls = true
1 is written to ctlSelOff
Then, stSeld goes from false to true
Finally we write the value of 1 to ctlOperOff and the relay closes
The RET670 in this project is configured to open in automatic mode following a logical sequence of opening and closing.
1. Our problem is that when writing the value of 1 in either ctlSelOn or ctlSelOff the variable stSeld does not take the value of "TRUE" and the column of "Quality" in ctlSelOn or ctlSelOff does not change to "Good" but to "UNCERTAIN" .
2. If I manually operate the CET and change the value from “1” to “49” the relay if it operates for opening and closing.
Why doesn't RET670 operate by typing "1"?
