b. Export Control Type.

 Type 1: Zero Export: to limit the exporting power to zero so that it can prevent the

generated power feed back to the grid.

 Type 2: Export Limit: to limit the exporting power within a certain value.

3.3 Remote Active Power Control (RS485 port)

Some countries require generating plants to be equipped with a logic interface (input port) in

order to cease output active power or limit active power to a regulating level. This logic

input can be RS485 port, Ethernet port, etc. MAC

DTU provide RTU Modbus protocol

over RS485 port for this remote active power control. For more information, please refer to

“Modbus implementation Technical Note”.
