Hello, From modbus, Im reading a HEX variable in the data register D0, as it is a 32 bit variable, the second part is saved in D1, then I get: D0: BE62 D1: 31D7 The value that I should obtain in float is -0.2208932 as I obtained setting BE6231D7 in online Hex to float converter and this agree with what I'm reading on the flowmeter. The problem is that when I try to change the data type from channel to Real on CX programmer I obtain a different value, also the registers are not sort in the proper way, instead they are sort inversely 31D7BE62, and obviusly the obtained value is completely different. Also instead of Hex, I want to display the decimal, or floating value, is there a way to do this? I'll attach some captures.

Hello, I am working on a Siemens S7-300 PLC with a WinCC HMI and I am looking to perform logging of certain values every 12 or 24 hours. Basically I have a Flow meter that constantly has flow through it. Right now I have the PLC set up to record the current value of the flow, as well as a totalizer to indicate how much flow has gone through the valve. (until an operator chooses to reset it) I need to create some sort of logic or utilize something in WinCC to calculate the flow through the valve only for that day. After that day, the value will be either deleted or replaced with a new value the next day... If anyone has any tips or advice it would be greatly appreciated. Thank you,
