Instruction Manual
Network Tab
Modbus TCP Setup Submenu
Use the
Modbus TCP Setup
pages to specify the network address and optional device parameters
of a remote Modbus/TCP device. Example remote Modbus/TCP devices may include another
Gateway device or any remote device using Modbus/TCP to communicate.
Devices
Map the remote Modbus/TCP device’s input and/or output using the
Client Read
and
Client Write
Maps
.
Connection Status: Connection status displays a non-zero error code when a socket error occurs.
Possible errors include:
Error
Description
104
Connection reset by peer
111
Connection refused
113
Connection aborted
114
Network is unreachable
116
Connection timed out
118
Host is unreachable
119
Connection in progress (connect unsuccessful and still trying)
205
Could not get host IP by name
Default Poll Period: The polling period defines how often this device (Gateway Pro or Ethernet
Bridge) contacts the device listed and solicits data. Enter the poll period in seconds.
Domain Name: The system may also look up an IP address when given a domain name. If the IP
address is set to zero, the system attempts to find the host by name.
IP Address: Specify the IP address of the remote Modbus/TCP device.
Local Name: The local name is an optional field and is used to refer to this device in other Web
Configurator pages.
Port: If port is left set to zero, port 502 is used. To use a non-standard port number, enter the
number.
Swap Double Registers: The term
swapped
applies only to double or float formats. Modbus
registers are, by definition, 16 bits of data per register. Access to 32-bit data, either 32-bit integer
(double) or IEEE 754 floating point (float), is supported using two consecutive registers. Modbus
protocol is inherently “big endian,” therefore Modbus defaults to having the high order register first
for double and float formats. If the low order register comes first on the accessed device, check the
Swapped box.
