Preface

Thank you for using GP-Viewer EX.
This GP-Viewer EX is software that allows you to display/operate 
the display unit's screen on the computer.

(1) Operating Environment
 Windows 2000 (SP3, SP4)
 Windows XP Home Edition (SP2) / Professional (SP2)
 Windows Server 2003 (SP2)
 Windows Vista Ultimate / Home Premium / Home Basic / Business / Enterprise 

(2) Applicable Models
 GP-Viewer EX is available to the display units with the network interface. 
 In this case, the screen project that has been edited with one of 
 GP-Pro EX V2.1, V2.2, V2.4 V2.5 and V2.6 must be transferred to the display units.
 For details on the applicable models, refer to "GP-Viewer EX Operation Manual".

(3) Limitations
 1. Portrait display is not supported. (Do not rotate the display unit.)
 2. When using double-byte characters for screen titles, 
    it may not display correctly in the Change Panel switch dialog. 
 3. In Data Display/Text Display, "Device" or "Device Type/Address" is
    specified in the Address Type, the display may be different from the
    server right after the connection is established. 
 4. If Global Window is set to "Indirect" and the data format is set to
    "BCD", the following restrictions apply.
    When Screen Mode is Asynchronous, moving the Global Window using 
    Add or Subtract buttons to change X or Y coordinates did not 
    operate properly.
 5. When a JPG file name in CF card or USB stick storage has any null
    characters, the JPG file is not loaded. Replace the null characters
    with other characters.
 6. In "Operation Lock":
  - When "Timeout" is short or there is a slave/GP-Viewer EX whose
    response is slow to a master's operation lock notification, the
    system variable "#H_IsLockOwner" of the display unit that has locked
    other display units remains ON.
 7. When GP-Viewer EX connects or re-connects to Display Unit,
    GP-Viewer EX sometimes displays different Alarms from those displayed
    on Display Unit.
    In this case, select "Screen Update" from the menu of GP-Viewer EX.

(4) Operation Manual Supplement
 1. Special Relay Area (LS2071-LS2074, LS2078-LS2095) cannot be written
    from the Viewer.
 2. You cannot open or save the settings file which is already open. 
 3. When using a long path for the settings file storage location, the
    GP may fail in acquiring data from external storage due to 
    operating system path length restrictions.
    Use short paths for the Settings file.
 4. When "Write GP-Viewer Data" is set to "Disable", 
    Viewer cannot lock the operation of Display Unit. 

(5)History of problems resolved
 Problems resolved in V1.60.400:
  1. Runtime of GP-Pro EX V2.60.400 is supported.
 Problems resolved in V1.60.300:
  1. Runtime of GP-Pro EX V2.60.300 is supported.
 Problems resolved in V1.60.200:
  1. Runtime of GP-Pro EX V2.60.200 is supported.
  2. Although Global Window is displayed on the display unit when "Synchronous Mode" is 
     specified for "Screen Mode", it may not be displayed on the GP-Viewer EX.
 Problems resolved in V1.60.000:
  1. Runtime of GP-Pro EX V2.60.000 is supported.
 Problems resolved in V1.51.000:
  1. Runtime of GP-Pro EX V2.51.000 is supported.
 Problems resolved in V1.50.000:
  1. Runtime of GP-Pro EX V2.50.000 is supported.
 Problems resolved in V1.20.000:
  1. Runtime of GP-Pro EX V2.40.000 is supported.
 Problems resolved in V1.11.100:
  1. Some defects of GP-Pro EX V2.21.000's Runtime were fixed.
 Problems resolved in V1.11.000:
  1. Runtime of GP-Pro EX V2.21.000 is supported.
 Problems resolved in V1.10.100:
  1. If you have installed GP-Viewer EX V1.10 before uninstalling
    GP-Viewer EX V1.00, uninstall GP-Viewer EX V1.10 and then install it
    once again.
  2. In "Operation Lock":
     - When a low value is specified for "Timeout" in Operation Lock and a
       heavy load is constantly applied to the CPU, the continuous
       high-speed operation may cause an error in GP-Viewer EX, which does
       not allow you to operate the connected master and the slave. In this
       case, exit the GP-Viewer EX where the error has occurred for restoration.
 Problems resolved in V1.10.000:
  1. Forced screen change is not supported. 
     Even if forced screen change is enabled, changing screens by touch
     from the Viewer is available. 
  2. At high communication speeds, changing multiple bits ON and OFF may
     not be recognized by the Viewer.
     The Viewer also may not recognize screen changes at high
     communication speeds. 
     As a result the Viewer may display different data from the server
     or reproduces a sound but it recovers on a screen change.
  3. When communication error occurred in a PLC, the Viewer stopped
     displaying the values of the other PLCs that were operating normally.
  4. In the "Update Data in Storage" dialog, specifying "All Folder" in
     "Image Data" does not enable the Viewer to load all the image files
     in Storage.
     For all the image files in Storage to be loaded, you should leave the
     "Folder (includes subfolders)" blank and press OK button.
  5. When "Update Data in Storage" is executed, the display of security
     level looks as if it has been changed (actually the security level
     isn't changed).
  6. The same message scrolls twice continuously by the banner alarm function.
 Problems resolved in V1.00.200:
  1. When a device/PLC was assigned to "System Area Start Address",
     it was unable to write to part of the PLC device.
  2. While the Viewer is acquiring the SRAM data,
     the display unit changes to off-line mode and recovers to on-line mode 
     without modifying setting.
     After that, the Viewer can not acquire the SRAM data.
 Problems resolved in V1.00.100:
  1. In the Sampling Settings, Mode tab, if you use the Data Full Bit 
     Address or the Block Completed Bit Address, each bit turns on twice 
     in a row as the condition is satisfied.
  2. Even if screen synchronization is set up, when you use Group with 
     Auto OFF in the Bit Switch group function, upon exiting GP-Viewer EX
     the Auto Off operation is run.
  3. When the CPU utilization 100% status is sustained, the application may become
     the no-response condition or an application error may occur. 
  4. When a data read/write is made at high speeds by the operations below, 
     the CPU utilization goes up and the problem of the item 3 occurs.
   - In Word Switch, select "Add Data", "Subtract Data" etc. and 
     check "Continuous Add Feature".
     When you keep clicking the switch on the screen, the CPU utilization goes up.
   - With "Read Data From Each Alarm" enabled, change the triggered devices
     at the same time to read a large number of devices at a time.
