Hello, i created a logo program for the control of a pumping installation with several watercontainers. the pumps are working depending the level of the water in the containers. the program itself seems to work perfectly. However, since I added a webpage to set the tresholds of the levels of the containers something seems to go wrong... values seem to chang by itself. Ex. set to 350.. .suddenly jumps to 6503... can somebody help me please. i will try to attache both files. Many thanks in advance. Kind regards, Nicolas Attachmentproject.zip (595 Downloads) |

And you have overlapping in the VM addresses. The adressing is byte-oriented. A word has 2 bytes. By a word give as the address the number of the first byte. Example: See you the overlapping? Both words use the same byte, VB1. VW0, VW2, VW4, VW6 and so on ... AttachmentLOGO! Bit, Byte, Word and DWord.pdf (687 Downloads) |
