See the release notes for a full list of changes included in this version

Fix: TopView DataPath on inaccessible network share may pause or crash the TopView Engine

TopView’s DataPath is a folder location that contains TopView configuration files and logs. The default location for DataPath is the local machine (C:\ProgramData\Exele\TopView).

Users with a failover/redundant TopView license may move the DataPath to a network share to allow sharing of configuration files and logs between the primary and failover TopView machines.

Issue: If DataPath is moved to a network share and the share becomes unavailable, the TopView Engine process may temporarily pause operation or crash

  1. Pause operation: If the Engine is configured to automatically apply configuration change, the inaccessible configuration file on the DataPath may be viewed as a changed file. The TopView Engine attempts to apply the changes and performs an internal restart where it waits until the DataPath is again available.
  2. Crash: the Engine may encounter an unhandled exception if it attempts to write to the application or alarm logs before item 1 is encountered. If this exception occurs the TopView Engine process will no longer be running.

Changes included in this update to address the issue

TopView 6.33.2

Incoming email via IMAP

TopView can optionally allow incoming email for alarm acknowledge and to request value and alarm reports. In previous versions of TopView, incoming email required a POP3 Server.

This release includes support for IMAP.

Admin Tools: View selected alarm actions

TopView 6.33.1 introduced Alarm Actions logs that record an individual alarm’s activity (active, return to normal, acknowledge) and related notifications and actions taken through notifications.

When viewing alarm information in the application log or alarm log (alarm active, acknowledge, return-to-normal), a button [View selected alarm actions…] will appear. Clicking the button will take the user to the Alarm Actions log for the selected alarm.

Mobile Web App: brute force mitigation, account lockout

After 5 failed attempts to log into an account, subsequent log in attempts will automatically fail until the lockout period of 10 minutes has elapsed.

This behavior can help mitigate brute force attacks upon a specific user account. Lockout affects each user account individually, so a lockout of one account will not prevent other users from logging in. A successful log in will reset the failed attempts count.

SCADA Connect status window

A TopView license may include SCADA Connect. For users with a SCADA Connect license:

Suppress footer in Email/SMS messages

A new option (Global Options>Notification screen) allows the user to suppress the TopView footer in Email and SMS messages for non-expiring purchased license users.

TopView 6.33.1

Microsoft .Net Framework 4.7.2 requirement

Previous TopView versions (6.25-6.32) required .Net Framework 4.6.1

This release requires .Net Framework 4.7.2. The installation/upgrade will check the TopView machine for the required version.
See the TopView download page for this release for off-line installation of the .Net Framework

Because of this new .Net Framework requirement TopView is supported on the following Windows versions:

Twilio support added for outgoing SMS Notification

Twilio support added for outgoing SMS Notification
Previous versions of TopView support sending SMS notifications through email (carrier supported) and cellular modems.

Twilio is a hosted platform for communication and allows products (like TopView) to use Twilio APIs to add capabilities like voice, video, and messaging to their applications.

This release of TopView allows users with a Twilio account to use the Twilio platform for delivery of SMS notification messages from TopView.
Note: this release does not support incoming Twilio SMS messages for alarm acknowledge or information request which is supported in TopView for SMS using cellular modems.


Redundancy/failover support for SMS using network cellular modems

TopView SMS Notification supports the use of networked cellular modems from MultiTech (rCell 100 Series).

When using networked cellular modems, TopView can now be configured with a primary and backup modem.

If a backup modem is defined the TopView Engine will automatically send through the primary or backup modem based on historical success and a configurable list of modem health indicators.

Web Configurator: new features

The TopView Web Configurator is a web-based TopView Configuration Tool providing many of the same configurations functions available in the desktop Configurator.

This is the second release of TopView to include the Web Configurator. This release includes the following additional functionality:

Alarm Actions Log

Previous versions of TopView include an application log that details all alarm activity and notifications sent for the alarms. When multiple alarms occur close together or notifications are sent over time, it can be difficult to isolate messages related to the activity of an individual alarm. Alarm Action Logs are designed to address this issue.

Alarm Actions Logs are a new feature of TopView that records an individual alarm’s activity (active, return to normal, acknowledge) and related notifications and actions taken through notifications (e.g. alarm acknowledge through notification) into a single, viewable log.

OPC feature updates

For TopView OPC/SCADA users we have implemented the following updates
