3.10

Summary

    Maintenance release.

New Features/Changes

  • Changed FTP transfers to set the FTP fail flag to true and not retry when a source file does not exist on the local side.
  • Added TrigInitDelaySet() to holdoff the initialization of triggers at startup.
  • Added incremental and duration retrigger options to RTC triggers.
  • Added array support in ISaGRAF REDUNDNT block.
  • Added Bricknet access to Digital Output PWM registers on Microbricks that support the feature.
  • Added ability to disable automatic "makes" in ISaGRAF when programs are downloaded.
  • Added HTML Help to all controls, menus as well as making the manuals available on-line. Expanded manual, updated screen shots, added ISaGRAF ICL functions section as well as a hierarchy overview section.
  • Quickstart guides are also in HTML Help format.
  • Added serial TUI mouse navigation for those TUI controls that support it.
  • Added self-triggering Network Events to all master protocols--not just Modbus Master.
  • Added DNS retry and retry time parameters to the Node | Settings | Ethernet/Serial IP tab.
  • Changed ISaGRAF data memory model to allow for larger than 64K program control files. Limit is now available memory in the controller.

Fixed Problems

  • Advanta was not configured to properly detect when the Real Time Clock battery was bad. Reading may have been arbitrary.
  • Thermal type devices that supported negative ranges would not read negative.
  • In the dialer feature, long messages would cause a sample overflow. This manifested itself as playing the remaining samples in the wave file.
  • Timings between phone numbers and phone number lists were not being set making it impossible to pause between calls.
  • Netevents configured as "Regmode | Auto" were always delivered as signed numbers.
  • Telnet TUI management on different TCP/IP port numbers did not listen properly.
  • TUI fields get shifted when blank label lines are used.
  • Redundnt block programs with large scan times could not complete data transfers properly.
  • Blocks doing Real Time Clock writes were not accounting for the Daylight Savings Time flag.
  • RTCSECWR function where it was not compensating for the century properly.
  • RUNTIME function block was not updating it's internal time while block was disabled. It also would not set the time unless the digital input was on.
  • TOTALIZE function block was not updating it's internal time while block was disabled.
  • Two Modbus TCP Slave sessions could not simultaneously monitor for communication on two TCP/IP port numbers.
  • Fixed problem where RS-485 trail delay could be affected by excessive sockets activity causing timeouts to remote I/O talking over RS-485 links.
  • Fixed problem where DNS lookups could cause the controller to stall for long periods of time on a failed lookup.
  • Fixed problem where high latency TCP/IP networks would cause monitoring sockets to stop accepting connections.

    • Added "Number of rings before answer" feature.

Fixed Problems

  • Fixed problem in Node Options (now Node Settings) TCP/IP tab where the Max Number of Sockets parameter would get reset to 8 whenever the dialog closed. This prevented the user from changing it when needed.
  • Fixed problem where Logfile Entries could overflow the logfile write buffer should large block sizes be used.
  • Fixed Delta Triggers from registers where a zero in the set point would cause a constant trigger. A zero in the set point register now disables the Delta Trigger.
  • Etherlogic and ScadaFlex Plus controllers can now recover from a brown-out condition (Power Fail Interrupt) without resetting.
  • Fixed problem where function blocks (such as the average block) could be configured in such a way to have other function block's data overwriting its values. This manifested intself in the average block because it had the largest data target for the misconfigured function blocks to corrupt.
  • Fixed problems in Advanta, Integra and Ultima Etherlogics where DI and PI Rates were not getting updated/configured properly at runtime.
  • Fixed problem where Bricknet dialup systems with multiple destinations or sessions would not be able to monitor and share the dialup modem properly. This caused problems for units dialing in.
  • Fixed problem where a logged alarm being acknowledged from a Dialer could cause system instability.
  • Fixed problem where telemetry file transfers used the wrong file specification for destination file.
  • Fixed problem where listening sockets could get out of sync between a listen and an open. This now monitored and flagged as a "listen error" which is recorded in the system.log file.
  • Fixed problem where the watchdog (when enabled) would cause a reset of the controller after a clean exit from the program. This caused download problems from ScadaBuilder.
v2.01

Summary

    Maintenance release.

New Features/Changes

  • Changed Modbus RTU system to work from message gaps thus eliminating rewind feature.
  • Added FTP status buffer update that shows how many bytes have been sent during the current transfer. Works with both Ethernet and PPP connections.
  • Added the ability to detect a failure on an FTP transfer no matter the reason for the file not being delivered (ie. loss of carrier or remote server disconnected).

Fixed Problems

  • Mapping DI Counters was indexed improperly in the Integra I/O driver.
  • Logfiles that were set to not overwrite archives could potentially archive every time the archive file was deleted or transfered off the controller.
  • Modbus RTU task could operate on unitialized data should a receive timeout occur causing the task to stop. No other protocols were affected.
  • Dialup Modbus sessions no longer pass token to other dialup sessions while a file transfer is active over the dialup link. The transfer will finish or fail out before the system moves on.
  • When using voice, it was possible that the system would not shutdown properly when doing a reset or termination of the program.
  • ISaGRAF 3.54 licensing would not work on some workstations and laptops.
  • TCP/IP would shutdown over a long period of time.
