Communicating with RMCTools
In addition to its primary communication type, each RMC has a Monitor port, which is
intended to be used to communicate with RMCTools.
The Monitor Port type varies by controller, as shown in the table below.
Controller Monitor Port
RMC75E USB
RMC75S RS-232
RMC75P RS-232
RMC150E USB
The USB Monitor Port can be used only for connecting to a PC running RMCTools. The RS-
232 Monitor Port is primarily for connecting to a PC running RMCTools, but it can also be
used to communicate via serial DF1 to other devices.
RMCTools can also communicate with the RMC75E and RMC150E via Ethernet.
See the Monitor Port topic for more details.
RMC150-to-RMC150 Communications
The RMC150 Universal I/O Module provides limited inter-RMC150 communications via
SSI. The communication transaction is performed each loop time, allowing for tight
synchronization between controllers, although only one 32-bit register can be sent and
one received. For details, see the Universal I/O Module topic.
Sample Projects
Delta provides free example projects for various host controllers, such as PLCs and HMIs,
for communicating with the RMC. These example programs will get you up and running
quickly. See the downloads page of Delta's website at deltamotion.com for example
projects available for the RMC.
Discrete I/O
Discrete I/O augments the communications of the RMC. Discrete I/O is typically faster
and more deterministic than the communications, and is therefore well-suited for starting
a sequence in the RMC at a specific time. For details, see the Discrete I/O for
Communications topic.
Register Map
The register map is the core of the RMC communications. It gives the addresses for all
the information available in the RMC. When communicating to the RMC from a PLC or
other host controller, the register map is a valuable reference. See the Register Map
Overview topic for details.
