ENET and 1756-ENBT).
See the EtherNet/IP topic for details on usage with the RMC.
FINS/UDP
This is an open application protocol developed and used by Omron Electronics Inc. This
protocol is available over a number of media, including Ethernet and serial. Additional
information is available in the CS1 Communications Reference Manual, available on
Omron's web site: http://www.omron.com/oei.
For more details, see the FINS/UDP and Communicating Directly over UDP topics.
ICMP (Internet Control Message Protocol)
This protocol—running on top of the Internet Protocol—is used for sending error
messages between routers and also provides the ping service. Only the ping service
portion of this protocol is used by the RMC. Ping is a utility provided on most operating
systems that simply asks if a device can be found with a given IP address or name.
IEEE 802.3 for 100BaseT
This is a standard for sending Ethernet data at 100Mb/s through twisted pair wiring rated
Category 5 (CAT5) or greater. The connectors used by this standard are RJ45.
IP (Internet Protocol)
This is the main Internet Layer protocol and is used for sending packets between two
computers in a network or across two or more networks. It also allows for fragmentation
of packets. This is a situation where a packet is larger than a network's maximum packet
size, so it is broken into smaller packets that are re-assembled by the recipient.
Modbus/TCP
This is an open protocol developed and used by Modicon of Schneider Electric. Its
standard is maintained by Mosbus-IDA (www.modbus.org). See the Modbus/TCP topic for
details on usage with the RMC.
Procedure Exist
The Mitsubishi protocol is for the Mitsubishi's Q-series QJ71E71-100 Ethernet module and
the FX3U PLC. See the Mitsubishi Procedure Exist topic for details.
PROFINET
PROFINET is the open industrial Ethernet standard of PROFIBUS & PROFINET
International (PI) for automation and is part of the IEC 61158 and IEC 61784 standards.
The RMC75E and RMC150E support the PROFINET IO portion of PROFINET, which allows
for data cycles down in the millisecond range. See the PROFINET topic for details on
usage with an RMC.
TCP (Transmission Control Protocol)
This is the main Transport Layer protocol in the TCP/IP stack. It provides for maintaining
a reliable connection between two devices.
UDP (User Datagram Protocol)
This Transport Layer protocol is used by some application protocols instead of TCP. UDP is
lighter weight than TCP and works well in situations where acknowledgements are built
into the application protocol or are not required.
If you wish to communicate with the RMC directly over UDP, see the Communicating
Directly over UDP topic.
