account security, change the password periodically and keep the new password in mind. Not
changing the initial password may cause password disclosure. A password left unchanged for a
long period of time may be stolen or cracked. If a password is lost, devices cannot be accessed.
In these cases, the user is liable for any loss caused to the PV plant.
•RS485-1, RS485-2, and RS485-3 correspond to communications ports COM1, COM2, and
COM3 respectively. This section shows how to set RS485-1.
•When setting Ethernet parameters, note that:
−If you set Auto obtain IP to Enable, IP addresses are assigned by the DHCP server on the
network. In this case, you must ensure that at least one DHCP server is working on the
network.
−The gateway address should be set to the router IP address.
−The SmartLogger1000 IP address must be in the same network segment as the gateway
address.
−The domain name server (DNS) address should be set to the router IP address or obtained
from the network operator.
•When setting NetEco parameters, set Address mode to Comm. addr. or Logical addr.. If the
devices connecting to the three RS485 ports of the SmartLogger1000 have duplicate
addresses, Logical addr. must be selected.
