I want to write multiple registers to my modbus slave so i am using the request : WriteMultipleRegistersRequest.

My modbus slave is a Telemecanique Twido (Programmable logic controller).

When I use WriteMultipleRegistersRequest, I get always the same exception :

net.wimpi.modbus.ModbusIOException: Premature end of stream (Header truncated).
at net.wimpi.modbus.io.ModbusTCPTransport.readResponse(ModbusTCPTransport.java:190)
at net.wimpi.modbus.io.ModbusTCPTransaction.execute(ModbusTCPTransaction.java:192)

I tried with the other requests and they work fine.

I tried (and it works) :
ReadMultipleRegisters
ReadSingleRegister
WriteSingleRegister

Do you have any clues of what happen with WriteMultipleRegistersRequest and/or WriteMultipleRegistersResponse?

Regards,

Arnaud
