USING TAGS
When acting as servers, many PLCs present their data in a tag format instead of implicit data format. For this
reason, when the client is configured as 'Client (Tags)', (see Section 6.7) 30 input and 30 output tags become
available to the user via iTools (Figure 33).

Figure 32 Explicit messaging example
FEC920: USER GUIDE
When wired to parameters which have
descriptors, the descriptor names appear
instead of the 'opc' names (e.g.
Loop.1.Setpoint.SP1) shown here.
Tags page appears if 'Mode' is set to 'Client
(Tags)' in EtherNet/IP configuration (Section
6.7).
Explicit messaging is not possible in tag IO
mode as tag mode needs to consume both
connections for communications with the PLC.
