MB Ethernet coils fail

[c-m]

I

I have the same problem with the MB Ethernet.
I need 40 Outputs.
The first 16 work perfectly. The next 8 coils do not work, next 8 work, next 16 do not work, next 8 work, next 24 do not work and work for the last 8. Conclusion, to activate the 40 outputs, I needed 88 coils.

 
Because 48 coil, do nothing. Someone can help me solve this?

There's a known bug in NI's Modbus library. Here is a corrected version.
