Hi,
    I want to write a multi tasking program. For this purpose I created two tasks. T_ROB1 and T_ROB2. T_ROB2 doesnt contains any movement instructions. T_ROB1 has a progam which needs data from a program in T_ROB2. How can I pass this data between these two programs?

    You can use a variable declared as PERS for the shared data. It must be declared in both tasks, but will be stored in shared memory.

    The problem with PERS is the value cannot be changed. I would like to get the position of the robot from T_ROB2 and send it to T_ROB1. T_ROB2 receives the robot position using TCP/IP communication from the camera.

    I think you can change the value of a PERS variable. It is the same as a normal variable except that it remembers the last value that it was assigned, even if the program is stopped and started again.

    Thanks for the help. With some modifications of my program it works with persistant variables.
