Features available in GP-Viewer EX are different than those used with the display unit.

Feature

Details

Switch

  • AUX Output cannot be used.

  • Special switches related to security, resetting, offline or other unsupported features cannot be used.

  • If switches overlap, or multiple switch functions are set up, operations may differ from the display unit.

Sampling Display

  • You cannot edit data.

  • First gets all sampling information, and then updates at the frequency specified in GP-Viewer EX. From the [Tool] menu click [Settings] and note the [Update Cycle] field.

  • Refine Search/Sort is available, but it does not synchronize with the display unit.

Alarm feature

  • The Sub Display feature may be executed at an unexpected time by operation on the display unit even when the Alarm part is not displayed.

  • Alarm information cannot be cleared by external operation.

  • Display content may be displayed differently than the display unit (time information, active alarm status, and so on). Touching the [Screen Update] button will update the contents by re-acquiring the alarm information.

  • You cannot save alarm information.

  • You cannot perform [Acknowledged] or [Clear] operation.

  • You cannot perform [Alarm Number Acquisition] operation.

  • If alarm analysis is used, the analysis list is not shown on the operation log.

Logic Programing

Global D-Script

Extended Script

  • You can review the results processed on the display unit, but the results of drawing are not reflected.

D-Script

  • This feature is enabled in Synchronous Mode. However, the results of drawing are not reflected.
    This feature may be executed even in Asynchronous Mode when the same screen is displayed.

Trigger Action

  • This feature is executed in Asynchronous Mode when the same screen is displayed. In this case, changing screens on the display unit does not change screens in GP-Viewer EX. Therefore, execution of [Start Application] or [Exit WinGP] cannot be confirmed by GP-Viewer EX, so do not perform such operations from GP-Viewer EX.

  • This feature is enabled in Synchronous Mode. However, the results of drawing are not reflected.

Screen Capture

  • The screen of the display unit cannot be captured with Screen Capture Settings. This should be performed from [Screen Capture] in the [Tools] menu.

Error

  • Displays errors on both the display unit and GP-Viewer EX.

  • All errors are acquired at first and then the information is updated at the frequency specified in GP-Viewer EX. Click [Change setting] and select [Information of Automatic update frequency].

  • Errors that are restored will not disappear. Such errors disappear only when the screen is changed.

Data Display

  • In Numeric Display or Text Display, when [Device Type Address] is specified for Address Type and a device (PLC) is used for Monitor Word Address, an error occurs.

Historical Trend Graph

  • You cannot review Cursor Information Storage Address, Status Address and Search Status of the Viewer.

Data Block Display Graph

  • In Asynchronous Mode, select [Block Display Graph] from the [Update (U)] menu to clear or redisplay the graph. Follow the same procedure when update does not happen in Synchronous Mode.

XY Historical Scatter Graph

  • Immediately after changing screens, all the data in the buffer is displayed on a graph, including the previously sampled data.

XY Block Display Scatter Graph

XY Historical Scatter Graph Normalization

  • When quickly changing the control word using D-Script or a PLC with ladder logic on the display unit, server operations may not be detected.

  • In Asynchronous Mode, when updating the graph, its Display Completion bit does not turn ON. Therefore, the control word cannot be returned to 0 on the display unit. Prior to updating, create a switch that returns the control word to 0.
