Release Notes for SEABUS QUCM Application ----------------------------------------- 01Apr08 - Added VAUX, min VAUX, max VAUX to 4720. 16Feb07 - Moved sqrt and converttoamps functions to subroutines inside pollseabus to avoid p1 p2 contention. Only one thread runs pollseabus function to prevent reboots. 01Sep06 - Ports never polled slaves. Bug from 24Aug06. 24Aug06 - Removed speed impact of the testing of writes to slaves. 01Mar06 - Added an offset for the Modbus Mode Port 2 so that the target slaves may be larger than drop 32. The Modbus/TCP index range is still 101 through 132 but the target drop now becomes Index - 100 + modbusoffset. For example if the modbusoffset = 32 then index 101 now hits device 33. 18Oct05 - Fixed SAMMS currents. Byte order was reversed and scale factor was not calculated correctly. 16Aug05 - Added check of Modbus write for each meter between polls to speed the response time for closing relays. Added check for new Min/Max on 4700 before polling min/max. 14Apr05 - Added adjustable max regtry count for both Seabus master ports. If the slave was online but fails to respond to a message then the QUCM will now retry up to the max count before marking the slave offline. Previously this was fixed at 1 retry. If the slave is offline then there are no retries. 05Apr05 - Fixed error in command for control bits 4700. 01Apr05 - Removed mask of relay control bits on 4700. 26Aug04 - Fixed Current Summary values display on web server for 4700 meter. 25Aug04 - Fixed Current values display on web server for 4700 meter. 03Jun04 - Added Control for 3 relays on 4700 meter. Register 3 now has these bit-mapped commands: bit 00 = clear KWH bit 01 = reset MIN/MAX bit 02 = clear Counters bits 3-6 N/A bit 07 = Reset relay 1 bit 08 = Close relay 1 bit 09 = Open relay 1 bit 10 = Reset relay 2 bit 11 = Close relay 2 bit 12 = Open relay 2 bit 13 = Reset relay 3 bit 14 = Close relay 3 bit 15 = Open relay 3 Send a write to register 3 with the appropriate bits set. When the QUCM has successfully performed the operation, it will clear the command bit. 10Mar04 - Fixed port 1 timeout on Seabus Slave and display on web page. 16Jan04 - Added more description on telent timeout. 25Sep03 - Added remote trip, close, aux relay on ST3. Register 3 now has the following bit-map. bit 0 = Clear KWH, KVARh, KWDemand bit 1 = Clear Min/Max bits 2-5 = Reserved bit 6 = Trip Breaker bit 7 = Close Breaker bit 8 = Open Aux Relay bit 9 = Close Aux Relay bit 10 = Trip Breaker Manual Enable bit 11 = Trip Breaker Manual Disable bit 12 = Close Breaker Manual Enable bit 13 = Close Breaker Manual Disable bit 14 = Aux Relay Manual Enable bit 15 = Aux Relay Manual Disable 28Feb03 - Nowrap on the meter names. 21Feb03 - Fixed possible stack underflow error on app1s. Fixed meter 1 and 2 name loss on power cycle. New app1, app1s, app2 and app2s. 14Feb03 - New web server. Fixed data ram conflict with program ram. Reduced number of devices to 50 for app1s and app2s for QUCM-SE. QUCM-LE still gets 100 devices and uses app1 and app2. 03Feb03 - Changed Modbus/TCP server to use an array of sockets. Added java script to auto-select password focus. Use runtime 23Oct2002 or later. 03Jul02 - New compiler and firmware. Must use 08Mar2002 firmware. 16Apr02 - New compiler and firmware. Must use 08Mar2002 firmware. Fixed display of NONE on empty configuration. Changed the writelock interlock between APP1 and APP2. Fixed the detection of a disconnectted RS232 cable. 08Oct01 - Changed App2 to not display abbrevieated STIII reply data. Added 1 retry if unit previously online. 02Jul01 - Added support for local access of QUCM registers by Modbus/TCP Index 255 through port 502. Only copy IP settings from flash if QUCM IP Address = 0.0.0.0 21Jun01 - Added Seabus Slave to port 2. Set the master's timeout larger than twice that of the port 1 timeout. Added settable timeouts for both ports. Added previous/next device links to the data pages. Added Current, Voltage, Energy summary tables. Added names for the devices. Added settable head and title for QUCM web server. 04May01 - Changed old 4720 to 3720 and added new 4720 support. 13Sep00 - Added 30 second timeout on sockets. 15Aug00 - Added FTP Server for backup. 19Jul00 - Fixed a problem with opcode 10 with Port 2 PNIM mode. Fixed an initialization problem with the parity on Port 1. 26Jun00 - Fixed a reply loss problem with Port 2 PNIM mode. 24May00 - Added support for the 4320 power meter. Fixed a problem with Modbus 100 random reads. Fixed Power Factor on ISGS, 4700, SB, STIII.
