modbus tcp function block writes only when value changes?
I´m currently working on a ModbusTCP connection to another computer.
A problem I found is that the function blocks seem to only write a value once when it has changed. They don´t write the same value again and again, which makes sense but I need it anyway (when the value is changed manually on the other computer I want to overwrite it automatically via Modbus). Is there a way to avoid/deactivate this behaviour?
Also I found that often the function blocks (read and write) need 3 loops or more to read/write the values. Is this normal or is there a way to optimise this? (IP is changed to 141.xx...)
Thanks and best regards!
