Important
Communication with multiple devices simultaneously cannot be achieved via
Ethernet.
For example, when a personal computer and the PLC are connected to the controller
via Ethernet, the communication established between the PLC and the controller
needs to be disconnected before a communication with the controller is to be
established with the personal computer using Smart Monitor ZW.
