Hi,
I tried to change the vector length: 1(dec), 2(dec), 10(dec), 16(dec) and all this with hex. I tested termination on FC Off/On. If I press the F1 or F2 button to send telegram, I see on FC that the Bus message count increase for 3, because the master did 3 retries but increase also a Slave error count. If I change the slave ID on FC, there is no message on this FC, just in a bus massage. That means the FC received the telegram. There must be some error, but I cant find it. I do not have the Modbus Poll licence. I did some tests with coils in modbus and FC, some times ago. And that time works corect. Does anybody see the solution?
