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 8 Series 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
Communications Card Option "C" - 2x Copper (RJ45) Ports
Modes: 10/100 MB
Two Ports: RJ45 (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, IEC 60870-5-104, IEC 61850 GOOSE, IEEE 1588, SNTP, IEC
62439-3 clause 4 (PRP)
Communications Card Option "S" - 2x ST Fiber Ports
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, IEC 60870-5-104, IEC 61850 GOOSE, IEEE 1588, SNTP, IEC
62439-3 clause 4 (PRP)
Wavelength: 1310 nm
Typical link distance: 4 km
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 port 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.
NETWORK 1, 4, 5, PRT1(4,5) IP ADDRESS
Range: Standard IPV4 Address format
Default: 169.254.3.3 (Port 1)
Default: 127.0.0.1 (Port 4, 5)
The setting sets the port's IPV4 address in standard IPV4 format.
The setting is valid on port 1 if the optional communications card is not present.
The setting is valid on port 5 if port 4's OPERATION is set to INDEPENDENT.
