Write Enable
Check
Write
to enable writing (when values encompassed by this service object
change in the gateway’s database, these changes will be written down to the
targeted device).
Parameter Code Selection
The read and write parameter codes may be selected, from “A” to “Z” along with
a command extension modifier by using both Function Code selection dropdown
boxes. Refer to the TCS Basys protocol functions for your specific device.
Service Object Status
If it is desired to reflect the status of this service object, check the
Reflect Status
checkbox and enter a database
address
between 0 and 4080 (0x0 – 0xFF0) at
which to store the status information. For more information on reflecting the
status of service objects, refer to section 8.5.2.

Configuration Example
This example will configure the gateway for end-to-end communication using
TCS Basys Master and BACnet/IP Server.
Say, for instance, we wish to communicate to a TCS Basys SZ1033 thermostat
from a SCADA system that supports BACnet/IP. We wish to monitor the room
temperature, outdoor air temperature, and heating and cooling setpoints. We
also wish to enable and disable the outdoor heat. The temperatures can be
monitored by mapping BACnet Analog Inputs and the outdoor heat enable can be
controlled by mapping a BACnet Binary Output.
Configure the Ethernet port using the above requirements
•
Connect the gateway to the PC via a USB mini type-B cable.
•
Open the configuration utility and select the ETH-1000 (see section 8.1 for
more information on selecting a device).
•
Click on the
Ethernet Configuration
subtab.
•
Click
Use a static IP address
and enter an IP address for the gateway to
reside at on the SCADA system’s network.
•
Check the checkbox next to
BACnet/IP
Server
in the
Protocol
dropdown
menu, and then click on the
BACnet/IP Server
subtab.
•
Enter a
Device Name,
device
Instance Number
, and the
Max Master
for
the gateway.
•
Create BACnet objects to map the data from the BAS into the gateway’s
database. The monitor object data will start at database address 0 and the
command object data will start at database address 100.
o
Create objects for temperature monitoring points
For the first object, enter the following:
•
Select
Analog Input
from the
Type
selection group.
•
Enter “Room Temp” into the
Object Name
field.
•
Enter “0” into the
Instance
field.
•
Enter “0” into the
Database Addr
field.
