Greetings,
If you would like to do customer modbus communication, you won't be able to use the modbus object in Lookout because it handles the communication for you, therefore you cannot customize it. What you will need to do is use the ASCII object, which gives you the ability to communicate with any device that transmits and accepts formatted strings of ASCII data. You will have to use the modbus protocol manual to put together a correctly formatted string and send it via the ASCII object to your device. This will give you the flexibility of using any modbus commands that you choose.
I hope that this helps. Good luck and have a good day.
Regards,
Patrick
