I am connecting an actuator by using RS485 communication line. I managed to communicate the actuator by reading its opening percentage number.
Now I want to write command into the actuator to change its opening percentage. I created a scheme editor with a button with send command action and mapped to an output channel with command number 1.
I entered a number of 10000 from web browser and successfully write the 10000 into the actuator. The actuator then opened to 100%.
My problem occur when I want to use formula at the output channel; I insert Cnl*100 into formula because I wish to enter a number of 100 in stead of 10000 in order for the actuator to receive command 10000.
But I saw write command 0 into the actuator and the actuator close to 0% after I entered 100 from web browser. Pls advice for what should I do.
