Message view
The TP 170A can display up to 16 messages in the message view. If more than 16
messages are present simultaneously on the operating unit, the oldest message in
the queue is deleted.
It is possible to define specific views of the messages to be displayed in the
message view. Various filter criteria is available for this in the configuration
software.
The following can be configured
Message categories (event and system messages only)
Number of columns
Number of lines per message
Sorting (oldest or latest message at the top)

Synchronize date and time
In order to synchronize the date and time on the operating unit with the PLC, the
area pointer Date/Time PLC must be set up in the project in ProTool/Pro CS.
During runtime, the operating unit accesses these data areas in the PLC for
reading purposes and synchronizes the date and time in the configured acquisition
cycle with the PLC. This data is provided, for example, in the message time
stamps issued in the message display.
Detailed information concerning the area pointers is provided in the
ProTool Configuring Windows-based Systems user's guide, in the configuration
software online help and in the Communication for Windows-based Systems user's
manual.
