v Master control Start

                    

                      MC is the master-control start instruction. When MC instruction executes, the program execution turns to the designated nest level and executes the instructions between MC and MCR.

v Master control Reset(MCR)

    MCR is the master-control reset instruction placed at the end of the designated nest level and no drive contact is required before MCR.

Address:- N0~N7

v Timer(TMR)

  When the present value in the timer equals the set value, the associated output coil will be ON. The set value should be a K value in decimal and can be specified by the content of data register D.

Address:- T0,T1,T2 etc for present value

K(any number) for set value

For ex: T0 K50 another ex: T0 D0.

v Counter (CNT)

   The counter count once (1 pulse) when the coil goes from OFF to ON. When the predefined counter value is reached, the associated contact will be energized.

Address:- C0,C1,C2 etc for present value

K(any number) for set value

For ex C0 K5 another ex: C0 D0

v Equal(EQU) (LD=)

                 SOURCE B:- H,K,T,C,D,E,F

v Not Equal (NEQ) (LD<>)

When the Source A is not  equal to Source B output is generated 

Address:- SOURCE A:-H,K,T,C,D,E,F

                 SOURCE B:- H,K,T,C,D,E,F

v Greater (LD>)

When the Source A is Greater then Source B output is generated 

Address:- SOURCE A:-H,K,T,C,D,E,F

                 SOURCE B:- H,K,T,C,D,E,F

v Less (LD<)

Address:- SOURCE A:-H,K,T,C,D,E,F

                 SOURCE B:- H,K,T,C,D,E,F

v Greater or Equal then(LD>=)

When the Source A is Greater  then or Equal to Source B output is generated 

Address:- SOURCE A:-H,K,T,C,D,E,F

                 SOURCE B:- H,K,T,C,D,E,F

v Less than or Equal then (LD<=)

When the Source A is Less then or Equal to Source B output is generated 

Address:- SOURCE A:-H,K,T,C,D,E,F

                 SOURCE B:- H,K,T,C,D,E,F

v Addition(ADD)

 When rung conditions are true, this output instruction adds Source A to Source B and stores the result at the destination address. Source A and Source B can either be values or addresses that contain values.

Address:-  SOURCE A:-H,K,T,C,D,E,F

SOURCE B:- H,K,T,C,D,E,F

DESTINATION :- T,C,D,E,F

v Subtraction (SUB)

When rung conditions are true, the SUB output instruction subtracts Source B from Source A and stores the result in the destination. Source A and Source B can either be values or addresses that contain values.

Address:- SOURCE A:-H,K,T,C,D,E,F

SOURCE B:- H,K,T,C,D,E,F

DESTINATION :- T,C,D,E,F

v Multiplication(MUL)

Use the MUL instruction to multiply one value (source A) by another (source B) and place the result in the destination. Source A and Source B can either be constant values or addresses that contain values.

Address:- SOURCE A:-H,K,T,C,D,E,F

SOURCE B:- H,K,T,C,D,E,F

DESTINATION :- T,C,D,E,F

v Division(DIV)

v Bit Shift Left(SFTL)

When the rung goes from false-to-true, the data block is shifted to the left (to a higher bit number) one bit position.

This instruction performs a left shift from source device of n2 bits starting from S to destination device of n1 bits starting from D

Address:-

 S:- Start No. of source device.

D:- Start No. of destination device.

n1: Length of data to be

shifted

n2: Number of bits to be shifted as a group

v Bit Shift Right(SFTR)

          When the rung goes from false-to-true, the data block is shifted to the right (to a lower bit number) one bit position. 

This instruction performs a right shift from source device of n2 bits starting from S to destination device of n1 bits starting from D.

Address:-

S: Start No. of source device

D: Start No. of destination device

n1: Length of data to be shifted
n2: Number of bits to be shifted as a group

Jump

               

 When Jump instruction is activated using Input the other output between Jump and Pointer ( P0) remains unchanged but when Jump instruction is not activated the Output between the jump and the Pointer can be changed

        Address :-CJ P0

Subroutine:-

              Subroutine is used to run two or more Ladders. When the Input is given to subroutine then Main Ladder and other Ladders will be activated . If the input is not given then only Main program will run.
