Delta RMC151 - Manual (Page 635)

6 Communication
Communicating with the RMC75E and RMC150E from other devices will use one of the
following four methods. Review each to determine which is appropriate for your device:
• PLC Ethernet Emulation
The RMC responds to several common industrial Ethernet protocols and can emulate,
or act like, several common PLCs. If your device supports reading and writing to
registers in any of these PLCs, then your device should be able to communicate with
the RMC. See Using the RMC’s PLC Ethernet Emulation for details.
• Standard Industrial Ethernet Protocols
The RMC75E and RMC150E controllers support several common industrial Ethernet
protocols, including Modbus/TCP, PROFINET and EtherNet/IP. If your device can make
requests in any of the RMC’s supported industrial Ethernet protocols, then it can likely
communicate with the RMC. See the Supported Ethernet Protocols section in the
Ethernet Overview topic for details.
• ActiveX Control or .NET Assembly
Applications that are running on a Windows PC and that support ActiveX Controls,
.NET Assemblies, or Microsoft Component Object Model (COM) can use Delta’s
RMCLink ActiveX Control and .NET Assembly. See the RMCLink topic for details.
• Direct over TCP or UDP
Third-party or custom controllers that do not support any of the above three methods
but can send and receive either TCP or UDP packets directly can communicate with the
RMC by manually building and parsing Procedure Exist packets over TCP or FINS/UDP
packets over UDP. See the Communicating Directly over TCP and Communicating
Directly over UDP topics for details.
Serial RS-232 and RS-485
The RMC75S supports serial RS-232 and RS-485. The RMC150 does not support serial
communication, but can communicate with serial devices via serial-to Ethernet converters
sold by other manufacturers. Contact Delta for more information.
Communicating with the RMC from serial devices will use one of the following methods.
Review each to determine which is appropriate for your device:
• Standard Industrial Ethernet Protocols
The RMC75S supports the several industrial serial protocols, including Modbus RTU,
DF1, and the Mitsubishi Bidirectional Protocol. For details, see each respective topic.
• ActiveX Control or .NET Assembly
Applications that are running on a Windows PC and that support ActiveX Controls,
.NET Assemblies, or Microsoft Component Object Model (COM) can use Delta’s
RMCLink ActiveX Control and .NET Assembly. See the RMCLink topic for details.
PROFIBUS-DP
The RMC75P and RMC150 can communicate via PROFIBUS-DP. For details, see the
PROFIBUS topic.
