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.

We have an install base of about 120 TWIDO PLCs anywhere from 1 to 10 years old with varying configurations, but all using the TWDLCAE40DRF base unit. Lately (over the past couple of years), we've had multiple instances where upon power being removed from the device, and then turned back on, the base unit fails and will not power back up. The typical case is that we turn on the power, a couple of LEDs flash for a brief (< 1 Sec) moment, and then nothing - unit is dead. Just wondering if anyone else has encountered the same thing.
