Inversed register order #15

Closed jonastim closed 4 years ago

jonastim commented 7 years ago

It seems that mbusd changes the register order for multi-register requests from what modpoll reads directly from RTU.

Modpoll reads 16bit (-t 4 flag) as register 57734: 6 register 57735: 0

32bit (-t:int flag) as register 57734: 6

inversed register 32bit (-t:int -i flags) "Slave operates on big-endian 32-bit integers" register 57734: 393216

With mbusd reading single registers results in the same values as with modpoll, but reading a 32bit word from register 57734 results in the register inversed value 393216.

Is there a way to retain the original register order / inverse the current order?

Isn't this a philosophy question (intel vs motorla) https://m.control.com/thread/1026161289 ?
