Lets you edit the information
below for the controller.
Touch a field to tap in new
information.
BACnet Device Instance number
Auto Generate Device ID-Enter No or Yes
You can edit the following
fields that pertain
to the controller's
MS/TP network:
Max Masters - Set this to the highest
MAC address
(up to 127) on the MS/TP network.
If
you later add a device with a higher address, you must change this field to that new
address.
Max Info Frames - Specifies
the maximum
number of information
messages
a controller
may transmit
before it must pass the token to the next controller.
CAUTION Increasing
this number
allows the controller
to transmit
more messages
while it
has the token, but it also increases
the overall time it takes for the token to pass through
the network.
•
Fora
router, set this value to a high number
such as 200.
•
In non-router
controllers,
use the following
formula
to calculate
this value:
[2 - (devices
* (.002 + (80/baud))]
/ [(600/baud)
* devices]
= Max Info Frames
For example,
if the network
has 15 devices at 19200
baud, Max Info Frames would be
4.
NOTE You may need to increase
the result of the formula
for controllers
that need to
communicate
many values to other devices.
