PLC logic setting example is as follows;
If user wants pulse signal output at OUT205 port when Phase fault indication occurrence, set the
PLC logic as the formula below.
Example: Logical Expression
1) ITM01 = FIA+FIB+FIC
When any one of following : Phase fault occurs, Logic Timer 01(TM01) is outputted. The
Pickup Time and Dropout Time of Logic Timer 01 is set in
“GLOBAL SETTING/ GENERAL/
PLC/ LOGIC TIMER” menu.
*. NOTE ) Phase Fault Indication Element related Logic Bit designation
① FIA : Fault Indication – Phase A
② FIB : Fault Indication – Phase B
③ FIC : Fault Indication – Phase C
2) IOUT205 = TM01
Map the output of Logic Timer 01 into the input of Output205 Pulse Timer. When the Pulse
Timer input signal is 1, pulse signal is outputted. Output pulse time is set in
“GLOBAL
SETTING/ GENERAL/ PLC/ OUTPUT PULSE TIME” menu.
3) BOUT205 = 0
As there is no block condition for Output205 port, 0 is always inputted.
The logic diagram for the logical expression example above is as “Figure 7-22. OUT205 Output
Signal Logic Diagram” .
