Set Modbus Gateway

Description	Sets the Modbus parameters for the IOLAN when it is operating as a Modbus Gateway.
User Level	Admin
Syntax	set modbus gateway [addr-mode embeddedre-mapped]
	[broadcast onoff] [char-timeout <number>]
	[req-next-delay <number>] [exceptions onoff]
	[idle-timer <number>] [mess-timeout <number>]
	[port <TCP/UDP_port>] [req-queuing onoff]
	[remapped-id <1-247>]
Options	addr-mode
	Determines if the original UID address will be embedded in the transmission header or
	if a specified (remapped) UID will be embedded in the transmission header.
	broadcast
	When enabled, a UID of 0 (zero) indicates that the message will be broadcast to all
	Modbus Slaves. The default is Off.
	char-timeout
	Used in conjunction with the Modbus RTU protocol, specifies how long to wait, in
	milliseconds, after a character to determine the end of frame. The default is 30 ms.
	req-next-delay
	A delay, in milliseconds, to allow serial slave(s) to re-enable receivers before issuing
	next Modbus Master request. The default is 50 ms.
	exceptions
	When enabled, an exception message is generated and sent to the initiating Modbus
	device when any of the following conditions are encountered: there is an invalid UID,
	the UID is not configured in the Gateway, there is no free network connection, there is
	an invalid message, or the target device is not answering the connection attempt. The
	default is On.
	idle-timer
	Specifies the number of seconds that must elapse without any network or serial traffic
	before a connection is dropped. If this parameter is set to 0 (zero), a connection will not
	be dropped (with the following exceptions: the TCP KeepAlive causes the connection
	to be dropped or the Modbus device drops the connection). The default is 10 seconds.
	mess-timeout
	Time to wait, in milliseconds, for a response message from a Modbus TCP or serial
	slave (depending if the Modbus Gateway is a Master Gateway or Slave Gateway,
	respectively) before sending a Modbus exception. The default is 1000 ms.
	port
	The network port number that the Slave Gateway will listen on for both TCP and UDP
	messages. The default is 502.
	req-queuing
	When enabled, allows multiple, simultaneous messages to be queued and processed in
	order of reception. The default is On.
	remapped-id
	Specify the UID that will be inserted into the message header for the Slave Modbus
	serial device. Valid values are 1-247.
