Figure 19: The NetLinx Communications & Diagnostics dialog
6.5.1.1. To enable TCP/IP communications between the Phoenix Server and the
NetLinx control system, select the [Enable] checkbox. To disable
communications, deselect the [Enable] checkbox. When connected, the
connectivity icon to the right of the checkbox will display a connected cable
and will turn green. When Phoenix communications are disabled or Phoenix
is unable to reach the NetLinx control system for any reason, the connectivity
icon will turn red and a disconnected cable will be displayed.
6.5.1.2. The TCP/IP Settings section is where the IP address of the NetLinx control
system must be entered.
6.5.1.2.1. Also within this section is the communication port. The port is
defined within the NetLinx code and is typically set at 1235, although it
may be changed if port 1235 causes any problems on your network.
This number must match the value defined within the NetLinx code.
Therefore, if you need to change the port then you should first contact
RealmCtrl and request revised NetLinx code that communicates on the
port that you need to use.
6.5.1.2.2. Also within the TCP/IP Settings section is the Timeout value. This
number is measured in seconds and it constitutes the maximum amount
of time that Phoenix will wait without receiving an acknowledgement
from NetLinx. If this timeout expires and Phoenix has not received an
acknowledgement from NetLinx for the last packet sent then it assumes
the communication link has been lost for some reason. In this case,
Phoenix will attempt to destroy and recreate the TCP/IP socket in an
effort to reconnect.
