Contents: ========= New Features, Enhancements and Bug Fixes How to Get Help ===================================================================== For Version 81.36 (05-18-2006): Bug Fixes ------------- (KB51599) Corrected a problem where the I/O unit incorrectly configured a SNAP-AITM-2, Type C thermocouple. The maximum reading was approximately 1550 ºC instead of 2320 ºC. For Version 81.35 (01-04-2006): Bug Fixes ------------- Corrected a problem that occurred when the brain was configured with an analog input module that was not physically installed on the mounting rack. Readings on a different analog input module could intermittently be incorrect. For Version 81.34 (10-20-2005): New Features: ------------- Added support for the SNAP-AIVRMS-i, SNAP-AIARMS-i, SNAP-AIMA2-i, and SNAP-AOA23-iSRC modules. Enhancements: ------------- Added enhanced communication link protection between the B3000 and analog modules. For Version 81.33 (04-27-2005): Enhancements: ------------- Special digital module only support. Use when faster event/reactions and repeatable communication loop times are needed from digital points. This firmware version does not support analog modules and requires replacing the flash EPROM chip. Contact Opto 22 Product Support (see "How to Get Help" at the end of this README) if your application requires faster digital processing. Please be advised, this version has not been fully tested and may not be suitable for critical applications. For Version 81.32 (03-15-2005): Bug Fixes: ---------- Changed re-initialization routine for channel 2 of analog modules. If an error occurred while the brain was trying to communicate with the second channel, the second channel would be taken offline and would not recover. The second channel would then read -32768, and cycling power was the only way to correct it. Changed initialization routine to properly identify and configure the SNAP-AIVRMS and SNAP-AIARMS modules. Caused periodic readings of zero or twice the actual value. Corrected scaling problem on SNAP-AIVRMS and SNAP-AIARMS modules. Corrected changes to scanning routine for all modules (introduced in 81.30/81.31). Corrected averaging on second channel for all modules (introduced in 81.30/81.31). Corrected random readings of 0 or -32768. Affects all modules (introduced in 81.30/81.31). For Version 81.31 and 81.30 (03-01-2005 and 12-03-2004): Enhancements: ------------- Changed I/O module scanning. Introduced engineering unit scaling for SNAP-AIVRMS and SNAP-AIARMS modules. For Version 81.29 (11-18-2004): New Features: ------------- Added support for the SNAP-AIV2-i module. For Version 81.28 (03-05-2004): New Features: ------------- Added support for the SNAP-pH/ORP module. For Version 81.27 (01-13-2004): New Features: ------------- Added support for the SNAP-AIMA-i and SNAP-AIMA-iSRC modules. Bug Fixes: ---------- Fixed Optomux command Z (affects digital Set Time Delay, Initiate Square Wave, Turn Off Time Delay/Square Wave, and High Resolution Square Wave commands). The command parameters were in the incorrect order. Corrected PID square root function to work with negative scaled numbers. For Version 81.26 (12-17-2002): Bug Fixes: ---------- Corrected PID problem where gain and setpoint parameters were changed. Required the following circumstances to trigger the problem: three or more PIDs on the same I/O unit, input is from host, and the PID is changed from enabled to disabled. For Version 81.25 (11-15-2002): Bug Fixes: ---------- Fixed averaging commands to work with RTD inputs. For Version 81.24 (06-11-2002): Bug Fixes: ---------- Changed code so that SNAP-AIVRMS and SNAP-AIARMS modules were correctly identified if there was an error communicating with the module. Correction affecting J type thermocouples in Optomux mode when counts are less than zero. Changes to SNAP-AIV-72 initialization routine. For Version 81.23 (03-21-2002): New Features: ------------- Added clamping to all analog output commands. Bug Fixes: ---------- Fixed PIDs so that the output doesn't go to full scale on initialization. For Version 81.22 (10-24-2001): Bug Fixes: ---------- Corrected information sent to SNAP-AOA-3-16 module.
