If the EtherNet/IP option has been ordered and enabled, the FEC920 can be configured as either a client
(master) or a server (slave) (see Section 6.7). The client and server displays are identical except that the
configuration area of the client display is more extensive than that of the server display.
Figure 27, above shows a typical set of display pages for an EtherNet/IP client.
CONFIGURATION OF IMPLICIT INPUT/OUTPUT TABLES
Configuration of the input and output tables is carried out via iTools drag and drop only by:
a.
Entering the parameters to be read by the client into the server output table.
b
Entering the destination parameter into the equivalent location in the client input table.
c.
Entering the parameters to be written by the client into the client output table.
d
Entering the destination parameter into the equivalent location in the server input table.
The example in Figure 28 shows this (using the FEC920 as the client) in graphical form, using just a few
parameters (there can be up to 50 in each table).

CONNECTION STATUS INDICATOR
A circular status indicator appears in a number of the EtherNet/IP display pages. This indicator can indicate the
following states:
Green rotating 'flash': the instrument is on line and at least one CIP connection is established.
Green flashing circle: the instrument is on line but no CIP connections have been established.
Red flashing circle: there is a break in the physical connection between the client and the server, or the
remote unit is switched off or is initialising.
