Custom Translation Tables
You can set up a translation table that an analog input will use to translate the raw data from a non-linear sensor
to the engineering units you want it to provide on the output wire of the Analog Input microblock. In the navigation
tree, select
Custom Translation Table #1
,
#2
, or
#3
. The
Properties
page has instructions.
For the input to use the translation table, go to the control program's
Properties
page >
I/O Points
tab. Click the
analog input in the
Name
column. On the
Details
tab, set
Sensor Type (Scaling Method)
to
Non-Linear, Custom
Table #__

BACnet Controller Properties
The
BACnet Controller Properties
page provides the following information plus the items described in the table
below:
•
The TV-VAVB3-E2's Ethernet MAC address
•
Whether
Port S1
is being used for MS/TP and is disabled
NOTE
The options shown on the page change according to your controller's settings.
MS/TP Configuration on Port S1
Address
For Port S1
—
A unique address on the MS/TP network.
MS/TP Autobaud
To enable autobaud, select
Yes
. This device will receive its baud rate from the
master device.
MS/TP Baud Rate
Set this to a baud rate that all other devices on the MS/TP network are set to.
Max Masters
To increase MS/TP performance, enter the highest address used on the MS/TP
network for a master controller. This number must be less than or equal to 127.
Max Info Frames
This is the maximum number of information messages a controller may transmit
before it must pass the token to the next controller. Valid values are 1 to 255.
TIP
Set
Max Info Frames
to a number in the range 20 to 100 so that the
router does not become a bottleneck for traffic being routed from a high-speed
network to the slower MS/TP network.
