Error with modbus client read/write functions

[sh4d0wlesss]

I tried read write coils/registers with modbuspal 1.6b version simulator with icssploit modbus client and metasploit module, ics give this errors and it can not read or write anything but msf succesfully did. (Tried on manjaro linux with python 2)

i saw this example from this blogpost: https://medium.com/@lucideus/industrial-control-system-exploitation-framework-lucideus-research-643cf563c42d

Hi @sh4d0wlesss can you provide the network packets during your test?
