Driver Manual (Supplement to the FieldServer Instruction Manual) FS-8700-73 BACnet MSTP - Serial APPLICABILITY & EFFECTIVITY Effective for all systems manufactured after February 2012 A Sierra Monitor Company Driver Version: 2.01 Document Revision:...
BACNET MSTP DESCRIPTION The BACnet Master-Slave/Token-Passing (MSTP) driver implements a data link protocol that uses the services of the RS-485 physical layer. See the FieldServer BACnet PIC statement for the level of conformance that this driver implements. All information in a BACnet system is represented in terms of objects. The Object_Identifier is a 32-bit code that identifies the type of Object (also identified by the Object_Type Property) and its "Instance"...

This section documents and describes the parameters necessary for configuring the FieldServer to communicate with a BACnet MSTP Server. The configuration file tells the FieldServer about its interfaces, and the routing of data required.

IP/MAC address. The default Network number of a FieldServer is 5. If there is more than one FieldServer on a BACnet intranet with multiple nodes, the default network number of the additional FieldServers will need to be changed and a unique number allocated to each.
Appendix A.4. FieldServer implementation of BACnet priority Arrays When BACnet Output objects are written to the Server side of the FieldServer, an associated write priority is given to each write value. When the FieldServer receives the write value, it stores it to the Map Descriptor Priority Array Table at the specified priority. The Priority Array Table is then scanned and the value with the highest priority is stored to the Data Array location specified by the Map Descriptor.
The maximum permitted length of any State_Text string is 50 characters.

The RecipientLists are not stored permanently but are kept in volatile memory, and subscriptions must be renewed on system restart. A permanent static RecipientList may be configured directly on the FieldServer, eliminating the need for a remote workstation to modify the RecipientList in order to receive Event Notifications. Using this option makes the RecipientList read-only, i.e.
Map Descriptor Example – Set up a Permanent Static Recipient List A permanent static RecipientList may be configured directly on the FieldServer, eliminating the need for a remote workstation to modify the RecipientList in order to receive Event Notifications. Using this option makes the RecipientList read-only, i.e. it can then only be modified via the FieldServer config.csv file.
The ReadPropertyMultiple (RPM) and WritePropertyMultiple (WPM) BACnet services allow many objects and attributes to be read and written in a single transaction. Since FieldServer Map Descriptors can only refer to a single object type and address range, a RPM or WPM transaction can be constructed by linking multiple Map Descriptors.

Mode of Operation when used for the Relinquish_Default property: When the FieldServer starts up, the standard BACnet operation for AO, AV, BO and BV objects is that the Present_Value of the object is set to the configured Relinquish_Default value. This may not be desirable in Gateway situations where the BACnet communications module (i.e.
Appendix A.12. Using a .ini file to set the Vendor_ID and Vendor_Name of the Device Object The vendor.ini file can be used to change the BACnet Vendor Name and Vendor ID if desired. A file with the following format must be created and downloaded to the FieldServer using the Ruinet “Download Configuration” command.
Appendix B. Troubleshooting Appendix B.1. Debugging a BACnet connection If duplicate Object_Instances are configured in the FieldServer, the second call of the Instance will overwrite the first one. This may cause a BACnet Object to be “lost.” If the Node Name configured on the BACnet Server Side of the configuration is not being indicated as the Device Name on the BACnet SCADA system, then the FieldServer is not communicating with the SCADA system.

If the number is higher than the transmit/receive messages, however, there may be a problem with lost communications..
Timeout errors may be experienced on start-up if the network is not yet fully synchronised or if there are a large number of nodes on the network. The FieldServer can only transmit the I-Ams a few at a time, and only when it receives the MSTP token.
McQuay Units are shipped with a default Device instance of the last 6 digits of the McQuay Serial number. Appendix C.2. Trane When new points are added to the FieldServer it is important to restart the Summit Workstation or BCU, otherwise these new points may not be seen by the FieldServer.
