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.
