7.8 Communications analyzer
The Communications Analyzer is a Windows® application that displays “messages” transmitted
to and received from an addressable device, such as a Modbus slave, by another Windows®
application. The messages are display from the oldest (at the top of the list) to the newest (at
the bottom of the list). The Communications Analyzer date and time stamps each message
displayed. After 4096 messages have been displayed, the oldest messages are cleared from the
list as new messages are added.
The Address combo box filters new messages so that only those with the selected address
(1-32) are displayed. By default, all addresses are displayed. The address filter does not affect
messages already displayed, only new messages.
