BACnet Standard Device Profile
This version of ACS320 BACnet fully conforms to the 'Application-Specific Controller'
standard device profile (B-ASC).
Services Supported
The following services are supported by the ACS320:
• I-Am (Response to Who-Is, also broadcast on power-up & other reset)
• I-Have (Response to Who-Has)
• ReadProperty
• WriteProperty
• DeviceCommunicationControl
• ReinitializeDevice
Data Link Layer options
The ACS320 implements:
• MS/TP (Master), baud rate(s): 9600, 19200, 38400, 76800
• MS/TP (Slave), baud rate(s): 9600, 19200, 38400, 76800
MAC ID / Device Object Instance
The ACS320 supports separate MAC ID and Device Object Instance parameters:
• Set the MAC ID using drive parameter 5302 EFB STATION ID. Default: 5302 = 1.
• Set the Device Object Instance ID using drive parameters 5311 and 5317.
Default: Both 5311 and 5317 = 0, which causes the MAC ID to “double” as the
Device Object Instance. For Device Object Instance values not linked to the MAC
ID, set ID values using 5311 and 5317:
- For IDs in the range 1 to 65,535: Parameter 5311sets the ID directly (5317
must be 0). For example, the following values set the ID to 49,134:
5311 = 49134 and 5317 = 0.
- For IDs > 65,335: The ID equals 5311’s value plus 10,000 times 5317’s value.
For example, the following values set the ID to 71,234:
5311 = 1234 and 5317 = 7.
Max Info Frames Property
Configure the Device Object Max Info Frames property using drive parameter 5312.
Default: 5312 = 1.
