PING DETAILS
Figure 26 Slave 2 ping initiation (Slave 1 similar)
The ‘Ping...’ field of the first slave is highlighted by default. As shown above, the down (or up) arrow can be used
to highlight the ‘Ping...’ field of the other slave instead.
Once the relevant ‘Ping...’ field is highlighted, the scroll key can be used to enter edit mode and the up/down
arrow key used to select ‘Start’. A further operation of the scroll key initiates the ‘Ping’ and if this is successful,
a green indicator appears alongside the field (and the text returns to ‘Ping...’). If the Ping is unsuccessful, then
the indicator is colored red.
The up or down arrow can now be used to return to slave 1, or the page key can be used to return to the previous
parameter display page.
As shown in the figure above, some diagnostic information is given. This includes the total number of successful
attempts that the master has made to communicate with the relevant slave, and the total number of failed
attempts. Fuller diagnostic details are to be found in the Modbus Master Communications configuration
description (Section 6.6).
