Section 4.2 Tag Communication Function
(a) Write parameters to the EtherNet/IP module using Utility Package.
(b) Confirm that all of the following signals are off before turning on the Tag
communication start request (Y00).
• PING test execution request (Y02)
• Flash ROM access request (Y06)
• TCP/UDP/IP parameter change request (Y08)
• Acquiring IP address (X0D)
(c) When Tag communication is started normally, the start addresses of send/receive
data and the status of reserved tags are stored in the following areas, and the Tag
communication start process completion (X00) is turned on.
• Class1 send/receive data start address (Un\G25856 to Un\G26367)
• Class3/UCMM send/receive data start address (Un\G26368 to Un\G26879)
• Reserved tag (Class1)(Un\G27168 to Un\G27183)
• Reserved tag (Class3/UCMM)(Un\G27216 to Un\G27231)
Upon completion of storing data in the above areas, Tag communication is
started.
The status and data of the Tag communication are stored in the following areas.
• Communication Status (Class1)(Un\G27136 to Un\G27151)
• Communication Status (Class3/UCMM)(Un\G27184 to Un\G27199)
• Input Area (Un\G0 to Un\G8191)
• Output Area (Un\G8192 to Un\G16383)
