After completing the RS485 network configuration, download the project to the CPU.
All CPUs and devices that have valid RS485 port addresses are displayed in the
"Communications" dialog.
You can access CPUs in one of two ways:
●
"Found CPUs": CPUs located on the RS485 network
●
"Added CPUs": CPUs on the RS485 network (for example, enter the RS485 network
address of a CPU directly that is on the RS485 network)
