SECRET: Standard Sequence Programming for PLC




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
Standard Sequence Programming Diagram The following example the use of Standard Sequence Programming (Input, Trigger, Output and Controller) in ladder diagram :
Standard Sequence Programming 1. Example Input Condition
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
Trigger And Sensor Condition Legend:
Tr : Trigger to Controller
C-1 : Output Controller 1
C-2 : Output Controller 2
C-3 : Output Controller 3
C-4 : Output Controller 4
S-1 : Sensor 1
S-2 : Sensor 2
S-3 : Sensor 3
S-4 : Sensor 4
I-2 : Input Condition 2
I-3 : Input Condition 3
STEP0 : Waiting Start = ON, Waiting All Origin = ON, etc.
STEP1 : Sequence 1
STEP2 : Sequence 2
STEP3 : Sequence 3

3. Example Output Condition
Output Condition Legend:
