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 8.4.2.
8.6.5.3 Configuration Example
This example will configure the gateway for end-to-end communication using
TCS Basys Master and BACnet MS/TP Server.
Say, for instance, we wish to communicate to a TCS Basys SZ1033 thermostat
from a SCADA system that supports BACnet MS/TP. 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 "RS-485 A" port (BACnet server) using the above requirements
•
Connect the gateway to the PC via a USB mini type-B cable.
•
Open the configuration utility and select the XLTR-1000 (see section 8.1 for
more information on selecting a device).
•
Click on the RS-485 A Configuration tab.
•
Select BACnet MS/TP Server from the protocol dropdown menu.
•
Enter the Baud Rate settings to match that of the SCADA system.
•
Enter the Address at which the gateway will reside on the network.
•
Enter a Device Name, device Instance Number, and the Max Master for
the gateway.
•
Create BACnet objects to map the data from the gateway's database to the
SCADA system. 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.
