8.7.11 Ethernet/CIP (P/N 1295-0519)
EtherNet/CIP provides the highly reliable communications like the other fieldbusses over fast,
economical Ethernet media. This interface uses ProSoft-Technology MVI46-DFNT hardware. In
the Vertex M this interface is always a server, never a client. For more information see
www.prosoft-technology.com and www.controlnet.org.
This interface provides 122 words of status information as listed in Table G-9. The presentation
of this data varies depending on the type of client used. Examples of this presentation are
included at the top of page 18 in the ProSoft User Manual and also in Table G-9.
WARNING
It is essential that Ethernet/CIP clients which communicate with the Vertex M monitor the
“Heartbeat” byte in word 40. This is because the MVI46-DFNT will continue to
communicate if Vertex M PLC ceases to run. External automation equipment must be
programmed to treat a failure of the heartbeat to increment as a complete loss of gas
detection.
