The format of PLC setting is AlarmPLC[A][B]=C.
Where, “A” is the row No., and “B” is the column No., and “C” is the value of the matrix element. An example is shown in the following table:
Table 5-7 Example of PLC setting
PLC byte | Byte description | Function |
AlarmPLC[3][0]=1 | Elemant value of Row 3 and Column 0 is 1. | Use Dry Contact 3 |
|
|
|
AlarmPLC[3][1]=1 | Elemant value of Row 3 and Column 1 is 1. | Alarm SN of Fuse 1 Blow up |
|
|
|
AlarmPLC[3][2]=3 | Elemant value of Row 3 and Column 2 is 3. | AND Logic |
|
|
|
AlarmPLC[3][3]=2 | Elemant value of Row 3 and Column 3 is 2. | Alarm SN of Fuse 2 Blow up |
|
|
|
AlarmPLC[3][4]=3 | Elemant value of Row 3 and Column 4 is 3. | OR Logic |
|
|
|
AlarmPLC[3][5]=43 | Elemant value of Row 3 and Column 5 is 43. | Alarm SN of LLVD |
|
|
|
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.
