You can read each level measurement by reading from the read block (input block) Word 1 for level 1 Word 2 for level 2 Word 3 for level 3 (differential) The value read will be % of level. One card per Hydroranger will allow you to read 3 points of level. |

Hi Mark, Thank you for your response. Am I correct in thinking that I need to put 3 separate values on the HMI. I ask this because when I monitor the values in S7, they are constantly changing greatly, some times going to a minus figure. At the moment I am not able to check this as I don't know when I am due back on site. The project I am working on at the moment has 3 differential instrument which is why I a asking these questions. |
