: Enter the name of the ProSoft gateway.
Note: The Notes field is for informational purposes.
Use the next 3 fields to configure the Ethernet settings for the gateway. An IP
address, subnet mask and gateway address must be assigned.
1 IP Address: The IP address must be a fixed IP address. Determine the
network settings for the ProSoft gateway, with the help of your network
administrator if necessary.
2 Subnet Mask: Enter the ProSoft gateway
’s subnet mask.
3 IP Gateway: The IP Gateway address is optional, and is not required for
networks that do not use a default Gateway.
Other fields to configure:
NTP
A
DDRESS
: This is the IP address for the SNTP Server. The gateway has a
SNTP Client in it, and the SNTP Server is the IP address which it can poll for the
current date and time. For example, in the USA, there are a number of time
servers and their IP addresses listed at http://tf.nist.gov/tf-cgi/servers.cgi.
NTP
U
PDATE
T
IME
: This number (in minutes) is the poll frequency at which the
gateway’s SNTP Client will poll the SNTP Server. A value of 0 (zero) means the
SNTP Server will not be polled.

Modbus registers. This addressing is so that Modbus Clients can access Modbus
data on the gateway. All of the tags in the ProSoft tag database are in a
numbered array of Modbus registers, addressed as 1
to 65535.

TART
: Valid values are in the range 1
to 65535, with a default value
of 1. A value of 1 means the first available Modbus read data register can be
accessed using a Modbus Holding Register address of 40,001 (or 400,001 if
using six-digit addressing). This is the starting Modbus address of the data in the
gateway’s tag database for read-only IED data. See the Modbus TCP/IP Server
Mapping (page 35) window to lookup the tag addressing.

RITE
S
TART
: Valid values are in the range
1 to 65535, with a default value
of 1,000. A value of 1,000 means 41,001. This is the starting Modbus address of
the data in the gateway’s tag database for writable IED data. See the Modbus
TCP/IP Server Mapping (page 35) window to lookup the tag addressing.
