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 everyone, I'm checking out the manual fot the S5 ET 100U due to some power supply problems in the factory I work. I've worked in projects with S7 PLCs and ET 200s, but these old PLCs and modules are still operative in the factory. I'm attaching a picture with an excerpt of the manual. What do they mean by floating and nonfloating modules, exactly? Thank you veyr much in advance.
