EMS for example).
You can select only Modbus for Protocol. You can select from 9600, and 19200 for Baud rate. The
value of Comm address ranges from 1 to 255.
The Baud rate and communication address of a single device must be same as that of the EMS.
Communication addresses of two devices must be different.
To perform communications settings, log in as the Operator user or other types of users that have
higher permission.
