Month: October 2007

Features

• The simulator now supports the PI function of the PCFL instruction.
• The simulator now supports the PID function of the PCFL instruction.
• The simulator now supports the KPID function of the PCFL instruction.

Solutions

• The Search by Reference Number function now properly finds implied references in instructions and network equations.
• The simulator now properly saves and loads 6x registers to and from a state file.
• A Machine Stop Code bit is set if a network has too many columns or an instruction has too many parameters.
• PID2 continues to solve if the Process Variable leaves the alarm limit range.
• The integral value is now solved correctly when PID2 is in manual mode.
• PCFL instructions can no longer be simulated in PLC types that do not support the instruction.
• Selecting a Momentum PLC type now properly writes default base data for drop 1 in the simulator.
• Both sides of a powered coil are highlighted when viewing power flow.
• Bits in the second implied register in PI, PID, and KPID functions are retained between solves of the loop.
• The Bit Sense function no longer stops the scan with an error condition when the middle node contains a 1x or a 3x register.

Features

• Headers may now be imported and exported for the “Delimited Documentation Text” format.
• The All Headers dialog now features Delete, Insert, Cut, Copy, and Paste functionality to quickly and easily reassign header information to other networks.
• Column widths in the Data Window are now saved with the program.

Solutions

• A network can now be added to an empty segment while in continuous mode.
• Performing a block move online when the high address in the move range is lower than the address of a used coil in the program no longer causes WorkShop to return a “Coil is already in use” error for the unused coil addresses specified within the range.
• Saving a program that contains an empty first segment while online with the PLC no longer results in an error when the program is opened offline.
• Added support for the Momentum I/O Bus module ARM 370 30.
• The FTVersionTrak Connect to Repository toolbar and menu item are no longer enabled when you connect directly to a PLC.
• Confirming changes made during a Replace Table function no longer causes WorkShop to unexpectedly close.
• A warning message properly appears when attempting to open an FTVersionTrak-tracked file that has been deleted or destroyed in the FTVersionTrak repository.
• Files loaded into the simulator can now be cross referenced properly.
• Segment headers that are deleted outside of the Segment Header Input dialog are now properly updated.
• The TAND function is now properly recognized as part of a network equation.
• Clicking the Help button in the Replace Table dialog now displays the appropriate help topic.
• Performing a fill in the data window in insert mode no longer overwrites the selected cell.
• Losing communication to the PLC during a search now correctly reports a response timeout.
• Losing communication to the FTVersionTrak database now correctly reports disconnection and no longer results in an error.
• Logging out of the PLC no longer has the potential to cause deadlock.
• Powerflow and ladder status are no longer turned off and disabled after an attempt to edit a ladder cell fails.
• Attempting to cancel a required checkout while working with FTVersionTrak now properly cancels the action.
• Attempting to compare a WorkShop file with unsaved changes using FTVersionTrak now properly displays changes when saved.
• Errors that occur while online in the data window as a result of an update from the communications server no longer have the potential to cause deadlock.
• Ladder status properly deactivates when saving to a program while online.
• Intermittent undefined server error messages no longer appear when ladder status is switched off.
• A network may now be properly be added to an empty segment while in continuous mode.
• Attempting to go to an empty segment from the All Headers dialog no longer automatically creates an empty network.
• Attempting to view a single segment from the All Headers dialog when no segments are selected no longer causes an error.
• Attempting to close a file containing network header at maximum size no longer causes an application error.
• Attempting to import headers when a network or segment header has been previously replaced by an empty header no longer causes the import to fail.
