I am working with a benshaw mxde3 module, and having some issues.
I can read all values just fine, but having issues writing.
The control values are all bits, and from the research I have do, this device does not support “MaskWriteRegister” therefore I cannot easily modify any bits.
I did find an old post from 2010, that had a script to do the job (http://forum.inductiveautomation.com/t/modbus-ua/2159), and I can now toggle bit values.
But when I toggle a bit, i get the following error.
even though it has successfully written the info.
