i am using control and simulation loop in which solver of RK 4 is used with step size 600 sec i.e. data is taken after every 10 minutes from sensor. in that Solver i am using Sub VI that is using RK 4 with step size 0.001 sec. if i change the sub VI configuration to step size 10 minutes then it doesn't work. i cant change the step size of of main loop as sensor data is coming after 10 minutes. if i change the main loop step size to 0.001 than all work good, but for step size 600 sec it doesn't work. please guide me
