The TPS-5000 in the control room must have three IP table entries (one for each
room) as well as the IP address for the control system. Following is a sample IP table
for the TPS-5000 in the control room.
IP Table: CIP_ID DeviceID IP Address/SiteName
3 192.168.001.010
4 192.168.001.011
5 192.168.001.012
6 192.168.001.015
For each IP table entry, there must be a corresponding device in each classroom
control system’s IP table. For example, in the control system IP table for classroom
1, there must be a TPS-5000 located at IP ID 03. In the control system IP table for
classroom 2, there must be a TPS-5000 located at IP ID 04. In the control system IP
table for classroom 3, there must be a TPS-5000 located at IP ID 05.

Without JNR, the system becomes difficult to maintain, as the programs for
classrooms 1, 2, and 3 must be different by virtue of the fact that the ID for the
touchpanel in each system has a different IP ID. Additionally each control system
must communicate to the panel using a different range of join numbers. When a
button is pressed on a panel, the signal on the corresponding join number will be sent
to every entry in the IP table. In our example, when join number 1 is pressed, it is
sent to IP ID 3, 4, 5, and 6. The goal is to make sure that each IP ID only responds to
a particular set of join numbers.
Without JNR, the control room would have to control each classroom by using a
different range of join numbers for each room. Any changes made in one room
would have to be made in all rooms. Maintenance and improvements become labor
intensive and impractical.
With JNR
Join Number Remapping allows a join number on a touchpanel screen (in our case,
the control room) to be routed out of the touchpanel on an IP ID with a different join
number.
