Standard Sequence Programming for PLC Programming is the original made in program-plc.blogspot.com and FREE for You
Standard Sequence for PLC Programming consists of :
1. Input Condition
2. Trigger And Sensor Condition
3. Output Condition, And
4. Controller
The following is a diagram of the Input, Trigger, Output and Controller
The following example the use of Standard Sequence Programming (Input, Trigger, Output and Controller) in ladder diagram :
1. Example Input Condition
Legend:
I-1 : Input Condition 1
I-2 : Input Condition 2
I-3 : Input Condition 3
O-4 : Output Condition 4
S-3 : Sensor 3
C-1 : Output Controller 1
PLC Input : PLC Input from PLC Hardware
2. Example Trigger And Sensor Condition
Legend:
Tr : Trigger to Controller
C-1 : Output Controller 1
