5 Ethernet
Communication
The SCADAPack 32P controller has one 10BaseT Ethernet port. 10BaseT is a single
communications channel running at 10MHz over unshielded, twisted - pair cabling. 10BaseT uses
differential signaling.
5.1
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
Refer to section
for the location of the LAN port on the SCADAPack
32P.
5.1.1 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 SCADAPack 32P
controller. Default values are set when a Cold Boot is performed on the SCADAPack 32P controller.
Parameter
Supported Values
IP Address
In the format 255.255.255.255
Default: 0.0.0.0
Subnet Mask
In the format 255.255.255.255
Default: 0.0.0.0
Gateway
In the format 255.255.255.255
Default: 0.0.0.0
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.
5.1.2 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
SCADAPack 32P controller. Default values are set when a Cold Boot or Service Boot is performed
on the SCADAPack 32P controller.
Parameter
Supported Values
Master Idle Timeout
Any value in seconds.
Default: 10 seconds
Server Receive Timeout
Any value in seconds.
Default: 10 seconds
Maximum Server
Connections
Valid values are 1 to 20.
