Class1 tag communications
Function overview
Class1 tag communications is a function for performing data communications between the RJ71EIP91 or EtherNet/IP devices
over a connection that has been established using tag names.
A Producer Tag and a Consumer Tag are used, and data communications are performed periodically between tags that have
the same Tag Name and Data Size.
Communication timing
Class1 tag communications are performed at the RPI interval set on Consumer.
RPI can be set for each connection.
Cyclic, Application Trigger, or Change of State can be selected for the communication trigger type. ( Page 79
