Many things can result in these symptoms. One of the most common causes is that not all slave manufacturers use a standard byte order. It is very possible that when you think you're sending a value of "1" to a slave's bit address 0, you may be sending a "1" to the slave's bit address 8. Enabling the Swap Input/Output Byte parameter would resolve the issue in this case. |
