Wrong Transaction Id returned by ModbusTcpSlave #39

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Create a ModbusTcpSlave
2. With a Modbus Master send a ReadHoldingRegister Request to the Slave
with TransactionId = 0

What is the expected output? What do you see instead?
The ModbusTcpSlave should return a response with transactionId=0 but 
returns transactionId=1 this produces an error on the ModbusMaster.

What version of the product are you using? On what operating system?
NModbus 1.8.0.0, VS2008 C# WinXP

Please provide any additional information below.
See the Wireshark Dump in the Attachment.

I was (erroneously) assuming 0 was not a valid transaction ID. Will fix 
shortly, 
thanks for the detailed bug report!
