PING DETAILS
Figure 1.4.12b 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 coloured 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 5.1.4.)
