4.3. Remote Modbus/TCP Device Configuration Page
All Modbus devices not configured remotely are assumed to be local, or connected to this gateway. The
location of all local Modbus devices is determined automatically. Access the Remote Modbus/TCP Device
Configuration page by clicking
Modbus | Remote Modbus Configuration
. Click the
Add Remote Configuration
button to add additional remote devices.
The following table provides details about configuration options.
TCP/IP Port
Default Port 2 = 503
Default Port 3 = 505
Default Port 4 = 506
Default Port 5 = 507
Default Port 6 = 508
Default Port 7 = 509
Default Port 8 = 510
The specified TCP/IP port(1-65535) that the ICDM-RX/MOD will listen for Modbus/
TCP requests on.
Default ports are the first seven unassigned ports, as determined by the Internet
Assigned Numbers Authority after the standard Modbus/TCP port of 502.
Note: TCP/IP ports 0, 22, 23, 80, 443, 4606 and 4607 are not allowed. Enabling
TCP/IP ports other than the defaults may cause disruptions on your
network. Please verify any configuration changes with your IT department.
Remote Modbus/TCP Device Configuration Page
Device ID #
The Device ID (also often called the unit ID) of the remote device must be unique.
The Device ID range is 1-255. 0 means that it is not configured.
Remote IP Address
IP address of the Modbus/TCP device. All 0s means that it is not configured.
Note: The IP address of the ICDM-RX/MOD will not be accepted as valid
configuration data.
Remote Modbus/TCP
Port (Default = 502)
The TCP/IP port (1-65535) to connect to on the remote device.
Timeout (ms)
(Default = 1000 msec)
The maximum allowable time (0 to 65535 msec) for a slave device to respond to a
message before the message is considered timed out.
Dedicated Connection
(Default = Off)
If selected, a dedicated Modbus/TCP connection will be used to connect to this
remote device.
Note: This is most commonly used when connecting to another gateway, multiple
devices are being accessed, and maximum bandwidth is desired.
Send Writes First
(Default = Off)
If selected, will forward write messages before forwarding any pending read
messages.
Note: This is most commonly used when multiple messages may be outstanding
for the remote device(s) and low latency for write messages is desired.
Disable Broadcast
Messages (Default =
Off)
If selected, will disable broadcasts to this remote device.
Note: If multiple remote devices are accessed through another gateway, then
this option must be selected for all remote devices configured to that
gateway to prevent broadcast messages from being sent to those devices.
