After setting your username and password, you can click the “Network
Configuration Page” button and a screen similar to that shown below will
appear. Use this screen to set the network configuration parameters for
your module. You may have to consult your network administrator to
complete the contents of this page.
An
IP Address
is a unique identification number for any host (this module)
on any TCP/IP network (including the internet). The IP address is made up
of four octets (8 bits), each octet having a value between 0-255 (00H-FFH).
It is expressed here in decimal form, with a period placed between octets.
A
Static IP Address
is as the name implies
—
static
, and represents a unique
fixed IP Address that is generally assigned by your service provider or
system administrator. The Default Mode static IP address assigned to this
module is 128.1.1.100 (refer to product side label).
NOTE:
In order to network your PC with an Acromag module, you may have
to consult with your network administrator and either temporarily change
your TCP/IP configuration (see TCP/IP Properties of Network Configuration
in Windows), or create a separate private network using a second network
adapter installed in your PC (recommended). The necessary steps will vary
with your operating system. Refer to Acromag Application Note 8500-734 or
document 8500-815 to help accomplish this (located on the CDROM
shipped with your module or via download from our web site at
www.acromag.com).
The
Number of Modbus Sockets
refers to the number (1-5) of Modbus
TCP/IP access points to allow for this host. The default allows up to 5
sockets, but you can restrict access by reducing this number

Note that Acromag Series
9xxEN Ethernet I/O modules
may take from 3 to 30 seconds
to boot upon power-up,
depending on your network
configuration and whether a
DHCP server is present.
This module can be placed
into a default communication
mode via the DFT push-button
at the front of the module. To
activate, hold the DFT button
for 5 seconds. The Status
LED will start a slow blinking to
indicate default mode.
Default Mode uses a static IP
address of “128.1.1.100”, a
default subnet mask of
“255.255.255.0”, a default
usernam
e “User”, and a
default password “password”.
