AlarmPLC[3][0]=1 Elemant value of Row 3 and Column 0 is 1.
AlarmPLC[3][1]=1 Elemant value of Row 3 and Column 1 is 1.
AlarmPLC[3][2]=3 Elemant value of Row 3 and Column 2 is 3.
AlarmPLC[3][3]=2 Elemant value of Row 3 and Column 3 is 2.
AlarmPLC[3][4]=3 Elemant value of Row 3 and Column 4 is 3.
AlarmPLC[3][5]=43 Elemant value of Row 3 and Column 5 is 43.
For the above PLC setting: When alarms of "Fuse 1 Blow up" and "Fuse 2 Blow up"
occur at the same time, or LLVD occurs, dry contact 3 will output the alarm signal.
