Answer question
Will we loose all operator setpoint if we load a new Freelance configuration?
One of our customers has a redundant Freelance AC800F to operate his boilers. We must add modbus communication to it and program data exchange with another system who acts as a modbus master.
On-site we must power off one controller at a time to install the new serial card. Then, we must program new communication hardware and function blocks.
Is it the kind of change that requires a full download? And will we loose all operator setpoints?
Another question:
We want to minimize time on-site and program those changes at our office and load them on-site once the new hardware will be installed. Will we loose all operator setpoints?
