Figure 4.3.16b Detect all slaves set-up menu
The ‘Detect All Slaves’ key is used to detect any slaves connected to the system, within certain search
parameters.
Operation of the button calls a display page (fi gure 4.3.16b) which allows the entry of a start IP address,
a range of IP addresses, and a range of Modbus addresses. In the above example, the search is carried
out for all devices with Modbus addresses in the range 1 to 2 inclusive, associated with instruments which
have IP addresses between 149.121.130.200 and 149.121.130.249 inclusive.
PARAMETERS AND KEYS
Network Allows the user to select a network to search over.
Overwrite existing slaves
The Auto Detect results page (see below) lists all the instruments found within the
search parameters, along with a ‘tick box’ for each one. Each instrument whose tick
box is enabled is assigned to the ‘Remote Device’ list in the Master Comms confi gura-
tion page. If ‘Overwrite existing slaves’ is enabled, then newly found instruments will
temporarily over write instruments previously confi gured there. The list becomes per-
manent when the Modbus confi guration page ‘Apply’ key is operated, but any of the
slaves can be edited, if required, prior to this.
Timeout The search for a slave is aborted if it does not respond within this time, and the search
moves on to the next slave.
From Node The start address for the search
For (nodes) The number of contiguous addresses to be searched starting with the ‘From Node’
address.
Modbus Address The lowest Modbus address for the search. The search will seek all slaves whose
Modbus Address lies between the value entered here, and the value entered in the
‘To’ fi eld, below, inclusive.
To The highest Modbus address to be included in the search.
Abort This key allows the user to quit the search
Start Once the search information has been entered, operation of the Start key causes the
unit to search for any instruments which respond to the search criteria.
Discard Returns to the Modbus confi guration page, without saving.
Apply Saves the details of the detected slaves to the Modbus confi guration page. The
changes to the confi guration page are temporary
Re-scan Allows the user to repeat the scan, with the same or edited search criteria.
