hello Thank you very much for your assistance and your always great help. I have a problem, in a new project, three temp transmitters( PIW 506, PIW 508 and PIW510) show 000 in the HMI. I connected my laptop to read the blocks. As you can see( please see the attachment file) they are identical as they are connected on three boilers. Take, for example, PIW506 the #out3 of the FC4 read -118.519, which is stored in DB310 in DBD28. however, when I opened the function to know how it was scaled and calculated I found the #out3 read 30.38 which equlas to the measured temp Can anyone please help me how this works and how to get the #out3 read 30.38, which then will be shown in the HMI Please note the input channel is configured in 4wire and the transmitters is powered and local LCD show 30C Thannk you very much in advance Attachmentjpg2pdf_compressed.pdf (214 Downloads) |

Thank you very much indeed for your response I am attaching herewith this post the online statue of FC4 as you can see the #out3 reads -118 (see page #1 in the attached file) Also, I opened and pictured the entire function which comes in four networks ( page 2-4) as you can see on page 4 the #out3 reads 28 My question is why is that? I think they should be the same, right? and please note that representation values are in auto option; I can change and choose decimal, hex or floating-point Thank you very much in advance the quality might be low as I had to compress the pictures Attachmentfile.pdf (194 Downloads) |

In the pdf of the first post came from all PIW's the value 8000 (hex). That is -32768 decimal. |
