I have several PoKeys 57E boards that I talk to via modbus-1.9.0-SNAPSHOT, one of them is giving me errors and I can’t see why.
2016-10-04 12:18:45 ERROR o.o.b.m.internal.ModbusSlave[:418]- ModbusSlave (second_ponet) error getting response from slave

The indexing starts from zero; I think you want to read/write coils 0-7 not 1-8. Reading coil index 8 from a modbus slave with config length 8 gives your error.
You should check your other coils correspond to the hardware channels you expect as well !

I originally started from 0, but it was not working right in hardware. The odd part is that I can control the relay 1 - 8 on the board.

I started at the wrong spot, I was starting at 2071 and should have started 2072. So 2071 + 1 was 2072 where as if I started with correct 2072 + 0 would be 2072.
