ID Description

Association of Device Feature in CCU Not Used by VersaPro.

Details: The CCU is a shared software component with the Control programmer. This utility

includes a feature called Association of device which is used by Control. This feature is not

supported in VersaPro.

Resolution: The Association of Device feature in the CCU should not be used with VersaPro.

CR70172

Incorrect error message when clearing PLC with Ethernet connection.

Details: With a direct connection to the PLC (CPU311 or CPU313) via an Ethernet

connection, if you select everything to be cleared in the PLC, VersaPro gives a message box

to the effect that a referenced memory address could not be written appears. When okay is

selected a second message box appears to the effect that a referenced memory address could

not be read.

Resolution: When the PLC is cleared, the Ethernet module will reset which prevents

communications to the PLC. This causes the error message to be presented and prevents

connection to the PLC during the reset period. Wait a few minutes for the Ethernet module to

re-boot and then try to connect again.

CR74357

VersaPro locks up tasks that require online monitoring while PLC is running if

OLE32.dll component is out of date.

Details: VersaPro locks up when the user attempts to perform any action that requires an

online update after initial connection and update are established. A serial connection is

established with VersaPro to a CPU that is in RUN mode. The logic is open, and VersaPro

performs an online update of the logic in the open window. Now if an attempt is made to

perform any action that requires a new online update (open reference table, scroll down a few

rungs in logic, open the status info. window, open another logic window, etc), VersaPro locks

up and does not respond to any mouse or keyboard actions. If multiple mouse clicks are made

on the main menu bar of VersaPro, nothing immediately happens, but approximately a minute

later VersaPro returns a message box that informs the user that the “Server is Busy”, and the

“action cannot be completed because the other program is busy. Choose ‘Switch To’ to

activate the busy program and correct the problem.” Selecting ‘Switch To’ causes the Start

Menu to invoke itself. Changing focus back to VersaPro causes the ‘Server Busy’ message

box to reappear. Selecting ‘Retry’ removes the message box and restores focus to the main

logic window, but clicking anywhere within the application causes the message box to return.

VersaPro must be shut down using the Task Manager, and both the HDRVSNP and GEFSVR

drivers remain active and must be manually terminated.

Resolution: VersaPro 2.0x requires OLE32.dll shipped with Windows NT 4.0 SP5 or

greater, Windows 95B, Windows 98 or Windows 2000 for communications to work properly.

It is possible for an older version of the file to be installed by another software package and

cause this issue. You should update the operating system so that the file has at least the

following revision: OLE32.dll Ver 4.0 dated 4/29/99:: 12:04 PM size 709KB or a later

version.

CR75866

At the end of successful store, VP loses connection to CPU363 PLC and auto reconnects.

Details: After a successful store of HWC, Logic and Stored Values, VP loses connection and

automatically reconnects to a CPU363 when connected directly to the serial port on the

CPU363.

Resolution: The CU363 will reset the serial port when a new hardware configuration is sent

causing the PLC to lose connection with the PLC. If this causes a problem for your

application, you should use the serial port on the 90-30 power supply.
