BACnet MS/TP Driver
This screen is used to configure access to a BACnet MS/TP network. This driver is only used when
connecting the BASview MS/TP module (BASV-MSTP) to the BASview. You can also communicate with
MS/TP networks through a BACnet router (BASRT-B)
— in which case you would communicate to these
devices through the BASview BACnet/IP driver.
Settings Tab
Label
Label is the name of the item as displayed in the
Device Tree .
All items in the Device Tree are sorted alphabetically by label. Folders can be used to organize items.
Description
Description is optional text that describes the item. It can be any descriptive text or be left blank.
Device ID
This is the device ID to use for the BASview unit itself. It must be unique for the entire BACnet network.
MAC Address
This is the MAC address or node ID for the BASview unit on the MS/TP network. It must be unique for
the MS/TP network.
Baud Rate
This is the baud rate used in the MS/TP network. The standard BACnet baud rates of 9600, 19200,
38400 and 76800 are supported.
Max. Master
This is the highest MAC address used on the network. Setting this too low may cause devices with
higher MAC addresses to not function properly. Setting it too high is inefficient, but will not otherwise be
harmful. If unknown, use 127.
Max. Info Frames
The number of frames or packets of data the BASview should be allowed to transmit each time it is has
control of the network (when it has the MS/TP token). The default of 1 is recommended.
APDU Timeout
This is the APDU timeout, in milliseconds to use for devices on the BACnet network. It should be set to
the highest APDU timeout used by any device on the network. Normally, it should be left at the default of
3,000 (3 seconds).
Group Settings Tab
These determine which user groups can see this item in the tree. Unchecking the default “Allow Everyone”
enables selecting individual groups. If a group cannot see an item, items under it are also unseen.
There ar e “Check All” and “Uncheck All” buttons in the upper-right corner to make major changes easier.
Advanced Tab
Name
Name is used for advanced features. If left blank, it will be assigned automatically. It is recommended
that the default value not be changed. It can be up to 48 characters. Only A
–Z, a–z, 0–9, period (.) and
underscore (_) are allowed. Names are case sensitive.
