Once you have obtained a list of devices in the Forformance
family (850-1650-1850) with the network option, if you select
one of the items in the list, the corresponding network pa-
rameters will appear in the top right (see illustration below).
There are only two ways of assigning values different from
the default values, and they are mutually exclusive :
• Fixed network parameters: set the new network parame-
ter values to be assigned to the device and press "Apply
changes" (see illustration below)
• Network parameters automatically assigned by DHCP
server: enable the corresponding item and press
"Apply changes" (see illustration below)
80209C_MHW_850-1650-1850_01-2020_ENG_pag. 246
Whichever method is used, if the assignment of new
network parameters is successful the following screen will
appear.
If it is not, nothing will appear in the box in the lower left.
Warning! Once the network parameters have
been changed by one of the two methods
described above, the device must be turned off
and on again to implement the change.
If no devices in the Forformance family (850-1650-1850)
with the network option are found upon completing the ini-
tial search (begun using the "Refresh list" button), the area
at the top left will remain empty.

Modbus TCP communication diagnostics
If the Modbus TCP communication option is installed but
there are errors exchanging data with the device where the
network interface card is assembled :
• the MAC.E parameter in the INFO submenu (add reference
to paragraph "4.4.6. MAC.E – Controller Ethernet address")
will display the value 0x:00:00:00:00:00:00.
• The INFO.E submenu (add reference to paragraph
"4.5. INFO.E Submenu - Displaying Ethernet information")
and the ETHER submenu (add reference to paragraph
"4.24. ETHER Submenu - Ethernet parameter set-up")
will not appear
If there are no errors, you will be able to obtain network con-
nection status by accessing the parameters in the INFO.E
submenu (add reference to paragraph "4.5. INFO.E Subme-
nu - Displaying Ethernet information").
