Digi 90000566_H manual Set ia

	set ia
set ia
Device support	This command is supported in Digi Connect WAN IA, Digi Connect SP,
	Digi Connect Wi-SP, Digi Connect ME4, Digi Connect Wi-ME,
	Digi Connect EM, Digi Connect Wi-EM.
Purpose	Configures selected Digi devices to support special parsing and bridging of
	Industrial Automation (IA) protocols. For example, it enables the Digi
	device to function as a Modbus/TCP to serial Modbus Bridge. Command
	options allow for configuring:
	• Protocol details of serial-port connected devices
	• Protocol details of network-based masters
	• Destination tables and route entries within the tables that define how
	protocol requests are forwarded to one of many slaves for a response.
	Supported IA protocols include Modbus/RTU and Modbus/ASCII on the
	serial port or encapsulated within TCP/IP or UDP/IP, and Modbus/TCP
	transported by either TCP/IP or UDP/IP.
	For more information on Industrial Automation, see the IA application help
	available at this URL:
	http://www.digi.com/support/ia
	Displaying current IA settings is best done by using the “show” command,
	as shown in the Syntax section below.
Required	For Digi Connect products with two or more users, permissions must be set
permissions	to “set permissions s-ia=read” to display the current IA settings, and
	“set permissions s-ia=rw” to display and configure IA settings. See
	"set permissions" on page 157 for details on setting user permissions for
	commands.
Syntax	There are several variants of syntax for the “set ia” command, depending
	on whether the command is being used to configure serial port-connected
	devices, network-based masters, or destination tables and route entries
	within destination tables. These syntax descriptions and their option
	descriptions are presented separately.
	Factory defaults for Industrial Automation settings
	The factory defaults for Industrial Automation settings are for a Modbus
	bridge with Modbus/RTU serial slaves attached. This configuration is also
	automatically created if you change the serial port profile to IA from another
	profile and there is no existing IA configuration. The default configuration
	is:
	• The IP address is assigned by DHCP client (there is no fixed IP
	address).
	• Internal DHCP server is disabled (off).
	• serial “term” login is disabled (off) (you cannot log into the serial port).
	• “set ia serial=1” assumes Modbus/RTU slaves are attached at
	9600:8,N,1. The protocol selected on the serial port is matched by an
