i make the hardware configuration between two cpu with dp and i want to write programe in ob1 to transfer one byte between two plc i use move instruction to move byte between two plc and and donot work in simulation can any one help me to write simple program in ladder to transfer data 

the data configuration

 Hello abdalla elneklawy,

Have look on the Detail FAQ from the DP DP Communication.

checked all step where you making the mistake.

Communication between 2 DP slaves

thanks mr emmy i make as i read in this link but i cant make  it in simulation
