Find Function
If the Modbus RTU documentation is not clear, then the
Find
function may be used to reveal the
Modbus RTU point addresses together with detail required to enter the points in to the MR point list.
The Find function is linked to point # 153 and is activated by entering
MRF
.
It is recommended to set
HyperTerminal to buffer the maximum 500 lines of displayed data to assist in reviewing the data received during
activation of the Find function.
Example 1: If you wish to reveal the point detail and activity of all points starting from Modbus address
30001, Read Input Register (Table 0/Row 0, F04) of a connected Modbus RTU device with address 1
then set up point 153 as follows:
153=1,0,0,0,4
(enter)
Example 2: If you wish to reveal the point detail and activity of all points starting from 42817 (Table
11/Row 0, RHR/F03) of a connected Modbus RTU device with address 25 then set up point 4 as
follows:
153=25,11,0,0,3
(enter)
Once you have set up point 153 according your search criteria then enter
MRF
.
T
he points from the
starting Table/Row will be sequentially displayed as in the example below. To Exit the Find sequence
enter TTTTTTTT… to revert back to the normal point listing.
Note
: When you exit the Find sequence the Table/Row detail at the scanning point at which you exit will
be inserted in to the point data of point 153. Please ensure the setup of point 153 is as you require it
before Writing (W) the configuration.
