The USB parameters are as follows:
IP Address: 172.16.0.2
IP Mask: 255.255.255.0
IP Gateway: 172.16.0.1
Whenever the device is rebooted, the USB cable needs to be unplugged and plugged in
again for proper communication to be established over USB.
Connecting multiple 845 relays over USB to a single PC is not possible because in the case
of USB, the IP address of the device 172.16.0.2 is constant.
The following communication offerings are available.
Base Offering
Modes: 10/100 Mbps
One Port: RJ45
Protocol: Modbus TCP, TFTP
Communications Card Option
Modes: 100 MB
Two Ports: ST (with this option both enabled ports are on the communications card; the
Ethernet port located on the base CPU is disabled)
Protocols: Modbus TCP, DNP 3.0 TCP, IEC 60870-5-104, IEC 61850 MMS Server/GOOSE,
IEEE 1588, SNTP, IEC 62439-3 clause 4 (PRP), TFTP, SFTP
Network Settings Menu
The following are the network settings menu of the 845 to accommodate the features of
the 845 product. If the communications card is installed network 1 is no longer available.
When using more than one Ethernet port, configure each to belong to a different network
or subnet using the IP addresses and mask, else communication becomes unpredictable
when more than one port is configured to the same subnet.
The softkeys and Down/Up key can be used to enter an IP address. When entering an IP
address you must press the "Back" key first to switch between softkey mode and the
Down/Up key mode.
