TCP Ports Numbers.
Each TCP/IP service has its own unique TCP port. It provides a logical location for the
delivery of TCP data.
TCP Port number complies to a standard defined by the IANA to be sure everyone using a
TCP service uses the same TCP ports according to protocols used.
When working with TB
OX
MS, in some cases, you might want to change this port number.
HTTP: port used to access TB
OX
MS as WebServer.
ModBus/TCP-Slave: port used by a ‘Master’ to access TB
OX
MS as ‘Slave’.
ModBus/TCP-Master: port used by TB
OX
MS as ‘Master’.
MTU.
The MTU determines the maximum size of a TCP frames, by default 1500 bytes. 1500
bytes is the maximum.
Some intermediate equipment (router, switch, …) does not support this value. It can then be
reduced.
TCP/IP addresses for incoming calls.
Range of addresses used during incoming calls.
TB
OX
MS uses the first address of the range and applies the following to the remote
equipment.
Typically, this information is needed when TB
OX
MS is used as a Web Server, dialed from

Avoid using addresses in the same range as the IP

1. Changing the TCP port does not affect access from
TWinSoft. This is always possible.
2. The changing of TCP port is automatically applied to
'WebForms' when building the HTML pages using
WebForm Studio.
