37.1.3 Differences from Display Unit - GP-Viewer EX

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.

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

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, drawing results 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.
