Section- 5 What is the NO and NC contact and output coil in a ladder logic diagram in Schneider TM200 PLC?

What is NO and NC contact in PLC?

NO – Normally Open – NO contact is normally open and becomes closed once its coil is energized

NC – Normally Closed – NC contact is normally closed and becomes open once its coil is energized.

Outputs from a PLC are referred to as coils on a ladder diagram. A coil may represent a motor, light, pump, counter, timer, relay, etc.

Example:-

Section- 6 Timer Instructions.

TON - ON Delay Timer

TON Timer:- If the input IN changes from FALSE to TRUE, switching on is delayed for the time interval set at the input PT. After the delay time set at PT has elapsed, Q is set to TRUE. The already elapsed time is indicated at ET.

NOTE:-

If the value applied at PT (Preset Time) is 0 or lower than the system’s cycle time and a rising edge occurs at input IN, output Q is not set to TRUE until the next cycle

TOF - OFF Delay Timer

TOF Timer:-

If the input IN changes from TRUE to FALSE, switching off is delayed for the time interval set at the input PT. After the delay time set at PT has elapsed, Q is set to FALSE.

Note:-

If the value applied at PT (Preset Time) is 0 or lower than the system’s cycle time and a falling edge occurs at input IN, output Q is not reset to FALSE until the next cycle.

Holding & Breaking Concept in PLC using Pulse Timer

TP Timer:-

If the input IN changes from FALSE to TRUE, a pulse is created at output Q for the time interval set at the input PT. The elapsed time while Q=TRUE is output at ET. If IN becomes TRUE for a second time before the time set at PT has elapsed, Q remains unchanged.

NOTE:-

If you want to use the standard function block TP in your code worksheet, you have to select the data type ‘TP’ for the function block instance in the local variables worksheet. Accordingly, the data types ‘BOOL’ and ‘TIME’ must be used instead of ‘SAFEBOOL’ and ‘SAFETIME’.

Section- 7 Counter Instructions.

Count up Counter (CTU)

Count up (CTU):-

In case of a rising edge at the input CU and RESET = FALSE, CV is increased by one. When CV reaches the value specified at PV, Q is set to TRUE and the function block stops counting. If RESET = TRUE, the counter is initialized with 0. To enable the counting process, RESET must be FALSE.

NOTE: If you want to use the standard function block CTU in your code worksheet, you have to select the data type ‘CTU’ for the function block instance in the local variables worksheet. Accordingly, the data types ‘BOOL’ and ‘INT’ must be used instead of ‘SAFEBOOL’ and ‘SAFEINT’.

Count Down Counter (CTD)

Count Down (CTD):-

In case of a rising edge at the input CD and LOAD = FALSE, CV decrements by one. When CV reaches the value 0, Q is set to TRUE and the function block stops counting. If LOAD = TRUE, the counter is initialized by the value of the input PV. To enable the counting process, the input LOAD must be FALSE.

NOTE: If you want to use the standard function block CTD in your code worksheet, you have to select the data type ‘CTD’ for the function block instance in the local variables worksheet. Accordingly, the data types ‘BOOL’ and ‘INT’ must be used instead of ‘SAFEBOOL’ and ‘SAFEINT’.

What is count up and count down counter in PLC?

Count UP/ Down (CTUD):-

. In case of a rising edge at the input CU, CV is increased by one. In case of a rising edge at the input CD, CV decrements by one. If CV = PV, QU is set to TRUE. If CV = 0, QD is set to TRUE. If RESET = TRUE, the counter is initialized with 0. If LOAD = TRUE, the counter is initialized with PV. To enable the counting process, the inputs RESET and LOAD must be FALSE.

NOTE: If you want to use the standard function block CTUD in your code worksheet, you have to select the data type ‘CTUD’ for the function block instance in the local variables worksheet. Accordingly, the data types ‘BOOL’ and ‘INT’ must be used instead of ‘SAFEBOOL’ and ‘SAFEINT’.

Section- 8 ADDITION, SUBTRACTION, MULTIPLICATION, DIVEISION, "Less than", "greater than" , "Move" Schneider PLC

Addition Operation

Addition:- This arithmetic function realizes an addition of the operands connected to the input parameters. It is available as standard function ADD.,

Subtraction Operation

Subtraction:- This arithmetic function subtracts IN2 from IN1. The function is available as standard function SUB.

Multiplication Operation

Multiplication:- This arithmetic function multiplies the operands connected to the input parameters and outputs the product.

Division Operation

Division:- This arithmetic function divides the dividend connected to IN1 by the operand connected to IN2 and outputs the quotient.

NOTE: Division by zero is not allowed and results in an error. As a result, the Safety Logic Controller enters the Stop state.

NOTE: As the output value must be of an Integer data type, a possible rest of the division is deleted.

Less Then Operation

Less then:- This comparison function compares the operands connected to the input parameters in regard to less. Comparison proceeds from left to right.

Greater Then Operation

Greater Then:- This comparison function compares the operands connected to the input parameters in regard to greater. Comparison proceeds from left to right.

Section- 9 :- How to scale Analog Input 4-20 mA signal?

When the analog input signal enters the PLC you will have to scale it in your PLC program.

Section- 10 :- Shift register | SHR (Shift right) & SHL (Shift left) instructions.

SHR: Shift bit pattern right.

This standard bit-string function performs a bitwise right shift operation on the standard WORD operand connected to the IN input. N specifies the number of bits to be shifted.

The following rules apply:

The “empty bit positions” resulting from the shifting operation are filled with zeros.
When shifting with N < 0, the function delivers the output value 0 because the N parameter is considered as an unsigned integer value.

Example: bitwise right shifting with N = 3 bits.

SHL: Shift bit pattern left

This standard bit-string function performs a bitwise left shift operation on the standard WORD operand connected to the IN input. N specifies the number of bits to be shifted.

The following rules apply:
