Ethernet Communication

The SCADAPack 350 controller has one 10/100Base-T Ethernet port. This is a single
communications channel running at 10/100 Mb/s over unshielded, twisted - pair cabling, using
differential signaling. It supports both half-duplex and full-duplex operation. The interface supports
auto-negotiation for both the speed and half/ full-duplex mode selection.
11.1

LAN Port Settings

Connections to the LAN port are made through a RJ-45 modular connector. The wiring and pin
connections for this connector are described in section 11.2-RJ-45 Modular Connector for
Ethernet.
Refer to section 3.2-Field Wiring for the location of the LAN port on the SCADAPack controller
board.
11.1.1

TCP/IP Settings

The following table shows the TCP/IP parameters supported by the LAN port. These parameters are
set from the ISaGRAF Workbench or from an application program running in the controller. Default
values are set when a Cold Boot is performed on the controller.
Parameter
IP Address
Subnet Mask
Gateway
The IP Address is the address of the controller. The IP address is statically assigned. Contact your
network administrator to obtain an IP address for the controller.
The Subnet Mask is determines the subnet on which the controller is located. The subnet mask is
statically assigned. Contact your network administrator to obtain the subnet mask for the controller.
The Gateway determines how your controller communicates with devices outside its subnet. Enter
the IP address of the gateway. The gateway is statically assigned. Contact your network
administrator to obtain the gateway IP address.
11.1.2

Modbus/TCP Settings

The following table shows the Modbus/TCP parameters supported by the LAN port. These
parameters are set from the ISaGRAF Workbench or from an application program running in the
controller. Default values are set when a Cold Boot or Service Boot is performed on the controller.
Parameter
Master Idle Timeout
Server Receive Timeout
Maximum Server
