Hey AHMADI.OUASSIM, I presume you are using the VlvlAnl block from the APL. If so you can find the commands and the description of the block in the APL manual: https://support.industry.siemens.com/cs/ww/en/view/109482346 |
Kind regards |

Hi Ahmadi, You have quite a lot of choices. Few things to consider, what signal did you get from the valves? Do you have open/close feedback? opening / closing? is it a Motor Valve? Do you need to send stop command? What is the type of the signal you got from the valve? Analog inputs and Analog Outputs only? Or profibus? If it is not a motor valve, and your control is just open close and variable signal, you may consider using VlvAnL and set the valve open close feedback monitoring to zero. (depend on your own preference. If the valve is a motor valve, you may use VlvPosL, you may open, close, stop and set the valve to positional ON to control variable speed. Hope it helps. |
