24-Point Continuous Monitor
Appendix A - Network Interface and Options F-20
A.12 Ethernet/CIP (P/N1295-0519)
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 A-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 A-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 the 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.
