BACnet router changelog

2.15  2017.10.19  Download

Redirect URL from “/” to “/?” to support Edge web browser (avoid keep asking authorization)

MSTP: Fix bug in standard state machine which would cause passing token to self when duplicated token is found.

MSTP: With standard state machine device in sole master mode would send max_info_frames * Npoll frames after polling one master. A more reasonable behavior is implemented that device send max_info_frames * Npoll frames after finish polling all masters.

2.14  2017.10.13  Download

Fixed bug introduced from 2.0, it should not wait reply when it send expecting reply request to mac address 255 on MSTP.

2.13  2017.9.19  Download

Potential bug (barely) may be triggered if MSTP auto mac and baudrate forcing are enabled together.

2.12  2017.7.10  Download

Optimizing route entry protection: Deletion from route hop will bypass protection.

Support devices utilizing 6.5.3 methods 1 and 4 for establishing the address of a BACnet router for a particular DNET.

2.11  2017.6.16  Download

This update help building up routing table quickly in large BACnet inter-network.

When BACRouter startups, it broadcasts out Who_Is_Router_To_Network without network number specified to learn routing info from other routers.

When Who_Is_Router_To_Network/Router_Busy_To_Network/Router_Available_To_Network without network number specified is received, BACRouter reports network number up to 1120 instead of 112 in previous version.

2.10  2017.6.13  Download

Bugfix: ReadRange on property_list should not return object_identifier; object_name; object_type.

Delay 1 second for sending Network_Number_Is when router startup, because if router is a BIP foreign device, the foreign device registering have not completed yet.

2.09  2017.6.10  Download

Protect route entry 60 seconds from last activity. Avoid broadcast storm in circular routing path.

2.08  2017.6.7

Bugfix: Vendor proprietary network message should be correctly relayed.

When relay Reject-Message-To-Network with reason 4(Too long), use unicast address instead of broadcast address.

Relax daemon’s max_apdu_retries to 10, in accord with WebUI.

2.07  2017.6.5

Compliant to BACnet Router and BBMD device profile.

Try to purge invalid route entry if no reply is received for Who_Is_Router_To_Network or Initializing_Routing_Table. This feature helps to rescue from mess network configuration.

Avoid sending too many I_Am_Router_To_Network with circular routing path.

Reduce memory consumption in complicated inter-network.

2.06  2017.6.1

Avoid BBMD broadcast storm. If Forwarded-NPDU is received from broadcast address, do not re-broadcast it.

When relay Reject-Message-To-Network with reason 1/2/4, use broadcast address.

Discard Reject-Message-To-Network with incorrect route info.

Check source net of incoming NPDU.(Trickily handle Initializing-Routing-Table)

2.05  2017.5.23

Bug: global broadcasted initializing-routing-table should be executed.

Bug: WebUI BIP mode select should not be applied without submiting.

Limit number of route entry in runtime info page to avoid request failure in very large internetwork.

2.04  2017.5.11

Fix WebUI Bug for verifying BDT.

Save configuration and restart when receive reinitialize-device service request.

2.03  2017.5.7

BIP BBMD NAT mode support udp port modifying.

BIP BBMD NAT mode do not listen to local net broadcast address and not send broadcast to local net.

BIP foreign device mode do not listen to local net broadcast address.

2.02  2017.5.5

Regards device sent Who-Is-Router-To-Network has no route to that network.(Delete that route entry from route table)

When Initializing-Routing-Table request modify network number of route port, I-Am-Route-To-Network is sent to report new network number.

Fix bug introduced by ver2.0 for saving new BDT modified by BVLL Write-Broadcast-Distribution-Table message.

2.01  2017.5.3

Add upgrade entry “http://ip/app/upgrade for rescue.

More intuitive log.

Improve network reject behavior.

Fix overflow bug when send I-Am-Router-To-Network(if network numbers reported > 738).

Sending I-Am-Router-To-Network at dynamic time interval.

2.0  2017.4.19

Option to enable Device object inside router.

Allow setting modification from BACnet side.

Support What_is_Network_Number and Network_Number_Is message

Option to support MSTP max_info_frames by occupy time.

Introduce MSTP new concept of auto/forced baudrate.

Guarantee of MSTP message delay(10 seconds).

WebUI is more intelligent.

1.22  2016.10.26  Download

Increase max route table entry from 1024 to 65534(unlimited).

1.21  2016.10.18

Slave Proxy: Increase ReadProperty(Multiple) sending rate if remote device is fast device.

BVLL response NAK for BBMD-related BVLL request but BBMD is not enabled. (Addendum 135-2012ax-5)

BVLL response NAK Upon receipt of a Distribute-Broadcast-To-Network message from a un-registered foreign device. (Addendum 135-2010ad-10)

1.20  2016.10.8

BIP provide option to accept buggy broadcast to 255.255.255.255

1.19  2016.9.23

Change webui reboot to restart, if IP/Netmask/Gateway/DHCP is not changed, fastly restart self

MSTP add fast device timeout interrupt feature

MSTP fast device minimums timeout is set to 0ms (actually 1.5bits plus 50us after turnaround)

MSTP fast device minimums token pass timeout is limit to 20ms

MSTP runtime info shows devices is active in past 10 seconds

1.18  2016.9.13

BIP BBMD support NAT, add two config parameter: “Accept BDT push from other” and “Accept foreign device register”.

Show Ethernet MAC address on “Setting” page.

MSTP add setting for Treply_timeout and Tusage_timeout.
