2.2.2 Communication ports
Communication ports provide communication between the RMC and host systems or external devices.
Factory preconfigured ports support typical communication scenarios. The ports support several
available communication protocols.
Ports configured for local communication (direct connection) support either local access from a host
system, or connection to external devices or peripherals (measurement transmitters, additional
automation or control equipment, flow computers or analyzers).
Ports configured for remote communication connect the RMC to a communication network and allow
remote access or management over that network.

2105552MNAE | RMC-100 | 17
The RMC has six communication ports. The design allows communication expansion to support future
external communication modules. Figure 2-6 identifies the ports and communication expansion
interfaces.

2.2.2.1 Serial communication ports
The COMM 1 and COMM 2 slots each contain a 40-pin connector to support a hot-swappable serial
communication module (Figure 2-7). This module is software-configurable for serial (RS-232, RS-485,
or RS-422) communication between the RMC and external measurement equipment such as pressure
or temperature transmitters, or communication equipment such as radio systems.
DANGER
–Serious damage to health / risk to life. Explosion Hazard: Do not connect
or disconnect connectors or their terminations while energized unles
s the area is known to
be
non-hazardous.
Figure 2-7: Hot-swappable communication module
The configured interface type and the distance between the RMC and the connected external device
determine maximum serial communication speed. Supported port speed ranges from 2,400 bps to
115,200 bps.
2.2.2.2 USB port
The USB Type B port provides high-speed serial communications between the RMC and equipment,
host systems or computers with USB interfaces. The port supports local operator access through
PCCU32.
The USB port has two speed modes: full speed and high speed. The RMC automatically negotiates
data transmission rates with the host system.
2.2.2.3 Ethernet ports
The RMC has an embedded managed Ethernet switch. It has two Ethernet ports (E1 and E2) for
communication between the RMC and external devices. Table 2-5 indicates the uses of the external
Ethernet ports.

–Connect other Totalflow equipment (for
example, XIOs, additional RMCs, flow
computers, etc.):
–Connect third-party Ethernet-to-serial
devices.
The RMC supports 2 modes for Ethernet port configuration:

2105552MNAE | RMC-100 | 19
–1 Network mode (E1 + E2): Configures both Ethernet ports into a single LAN (2-port switch) and
combines network traffic on both ports. This is the RMC’s default Ethernet configuration.
–2 Networks mode (E1, E2): Configures Ethernet ports into two separate and independent LANs.
This separates network traffic for each port. This option isolates network traffic on one port from
the other. Communication between these two networks requires an external router. Each
Ethernet interface must have its own IP parameter configuration.
Ethernet mode selection depends on field configurations, cybersecurity requirements, type of ABB
devices connecting to the RMC, and available network equipment. The 1 Network mode can simplify
device management and IP configuration. For more complex applications, the 2 Network mode may be
required.
IMPORTANT NOTE:
For additional details on Ethernet connections click Help on the Networking
tab when connected to the device with the user interface (PCCU32)
.
2.2.2.4 MMI port
The onboard MMI port provides an RS-232 (EIA/TIA – 232) serial interface. MMI access or direct
connection from a PC or laptop is only available on the port on the enclosure. Direct connection to the
onboard MMI port requires a special cable adaptor not shipped if the RMC is ordered for a standalone
installation. Weatherproof MMI connectors are available on all Xcore enclosures.
The port is factory-configured to support local operator access using PCCU32. The supported port
speed ranges from 2,400 bps to 115,200 bps.
IMPORTANT NOTE:
The MMI interface is included in the RMC design to support legacy systems.
Connections to the enclosure's military
-type connector require cable adapters to support RS-232
interfaces on older PCs or laptops. Legacy systems with
traditional DB-9 serial interfaces require
DB
-9 to military-connector cables. Newer PCs or laptops do not have legacy RS-232 interfaces.
Therefore, additional cable adaptors or converters are still necessary (DB
-9 to USB converters, for
example). The Digi
®Edgeport®
/1 converter is recommended and can be purchased from ABB (part
number 1801382
-001). Contact technical support to order, or for more details.
Enclosures include Ethernet and USB ports, which provide faster and more convenient local access
options
than traditional RS-232. If possible, use the USB or Ethernet ports.
2.2.3 Inputs/Outputs
Inputs allow you to read and monitor signals transmitted from external devices. Outputs send signals
to control external devices. The following I/Os are available on the RMC board:
–6 Digital Inputs and Outputs (DI/DO)
–4 Analog Input (AI)
–1 Analog Output (AO)
–2 Pulse Inputs (PI)
The I/Os operate in failsafe mode during communication loss, power loss, restore, or processor reset.
The failsafe mode maintains the last input or output values when an event occurs.
Figure 2-8: Inputs and outputs identifies the inputs and outputs.

and input ground pin. For specific pinout information, see section 3.5.5.1 Analog input pinouts.
Each of the four analog inputs (AI) consists of an analog input point capable of handling voltage or
current inputs. The voltage range is 0-30 Vdc. The current range is 4-20 mA.
