GENERAL DESCRIPTION
The OpenDAC
face is a remote slave that responds to
Modbus/TCP commands that it receives over
the network. The status and configuration of
up to 32 OpenLine
nels is stored and constantly refreshed.
OpenDAC
power up, the controller will identify the types
of I/O modules present. The unit will then con-
tinuously scan and update the digital and ana-
log modules. Digital input channels can be
setup for latching operation. The OpenDAC
for Ethernet supports the OpenLine
Module Protocol (SMP) that allows field cali-
bration and parameter setup of I/O modules.
Each OpenDAC
network is assigned a unique IP address. There
are three methods of assigning the internet
protocol address -BOOTP, DHCP, and a static
method. The controller is shipped with the default
IP address of 128.0.0.1. The IP address can be
changed using a web browser. The web browser
can also be used to select BOOTP or DHCP to
assign the IP address. Communication data
rates are either 10 Mbps or 100 Mbps.

from the Modbus/TCP master. When the
watchdog is enabled and the slave does not
receive a valid Modbus/TCP message within a
specified time, the OpenDAC

a valid message be received, the timer is reset
and communication resumes. All configuration
parameters are displayed and modified using a
web browser. The configuration parameters
are password protected to provide security
against unauthorized access.
