5 Power the RMC  
This section describes two modes for powering the controller:  
Battery mode: Power is supplied by a 12 volt battery with a charger (see section 5.2.)  
External power mode: Power is supplied by an external power source (see section 5.3.)  
Review section 5.1, follow the instructions for the appropriate power mode, then continue to section 5.4  
NOTICE – Equipment damage. Power compatibility for TFIO modules depends on module  
generation:  
Older green modules must only use 12 Vdc.  
M2 modules and newer gray modules can use 12 or 24 Vdc.  
A combination of green modules and M2 modules or gray modules must only use 12  
Vdc.  
5.1  
Power on sequence  
The RMC power on sequence is initiated as soon as power is connected. The following information may be  
displayed on the LCD as the controller completes its startup:  
ABB TOTALFLOW RMC-100: identifies the controller name and model  
BOOT 2105412-XXX: indicates the version of the boot software  
OS 2105411-XXX: indicates the version of the operating system  
Super CAP Charged: indicates if the super capacitor is charged (see section 5.1.1.)  
APP 2105457-XXX: indicates the flash version  
IMPORTANT NOTE: The scrolling duration of the displayed items may vary. When the  
DATE/TIME displays, the power on sequence is completed.  
2105551MNAD | RMC-100 | 17  
         
5.1.1  
Super capacitor  
The RMC design includes a super capacitor (Super CAP) that serves as a short-term power reservoir. The  
first time that the unit is powered up, or if the RMC is left powered off for several hours or longer, the  
boot time is approximately 2 minutes to allow for charging of the super capacitor. Once the capacitor is  
fully charged, the boot time is considerably less.  
IMPORTANT NOTE: In the event of a loss of power or reset, the charged super capacitor  
prevents the supply voltage from falling to zero for a short period of time (2.5 seconds).  
This delay allows the system time to save all persistent data such as trending, restart  
configuration, etc.  
5.2  
Power with battery and charger  
This powering mode requires a 12 volt (SLA) battery and a charger to recharge the battery. The following  
instructions describe the typical installation of a battery and solar panel system as the charger. These  
instructions should be adapted for alternate installations.  
IMPORTANT NOTE: Make sure the battery and charger meet the specifications  
requirements given in section 2.2.  
5.2.1  
Connect the battery (dc power)  
The hardware required for a battery installation is a 12 volt sealed lead acid (SLA) battery and the  
battery cable. Before installation, inspect the battery cable and connectors for breakage where they  
terminate on the battery. To install and connect the battery:  
1. Install and secure the battery where it will be used.  
WARNING – Bodily injury and property damage. Do not allow the battery terminals or  
cable ends, if attached, to come in contact with any metal surface. When the positive and  
negative battery terminals contact a conductive material, this creates a short circuit and  
could result in sparks, property damage, and possible explosion.  
2. Connect the battery to the terminals (Figure 5-1). The power terminal block is green. Observe the  
polarity (+ and -).  
WARNING – Bodily injury and property damage. All wiring of peripheral or external  
devices to the controller should be completed prior to applying power (connecting the  
battery). Connect the battery before connecting the charger cable.  
Figure 5-1: Battery port

BAT CHARGER/EXT PWR  
3. Confirm that the battery is supplying power to the RMC by observing the power on sequence  
information scrolling on the LCD (see details in section 5.1). When the DATE/TIME display, the  
sequence is complete.  
4. If the power on sequence fails to initiate or complete, press the reset button shown in Figure 5-4.  
5.2.2  
Connect the charger  
The RMC may use a solar panel (20 Watt or less) with Nominal 12 Vdc output voltage. The solar panel  
may be mounted on a 2 inch pipe or the top or side of a meter house. Call the ABB main office number  
18 | RMC-100 | 2105551MNAD  
         
listed on the last page of this guide for questions about mounting the solar panel on the top or side of a  
meter house.  
NOTICE – Equipment damage. Alternate installations could use a power source instead of a solar  
panel charger. When using a power source, the output must be 14.5 Vdc to 15.5 Vdc maximum as  
described in section 2.2.  
Failure to use chargers that meet the required voltage specifications may cause equipment  
damage.  
Exercise caution when handling the solar panel to avoid damaging it.  
For optimum charging, avoid placing the solar panel where it will be in shadows for any part of the day.  
The hardware required to connect the solar panel to the RMC is:  
One solar panel with an integrated cable  
One solar panel mounting kit  
NOTICE – Equipment damage. Never connect the solar panel or alternate charger cable to the  
RMC before the battery is connected to the BAT port (Figure 5-1).  
To connect the solar panel charger (adapt instructions if connecting to a power source as a charger):  
1. Verify that the solar panel is operating properly before installation:  
a. Check the solar panel using a digital voltmeter to verify polarity and output voltage. Voltage  
varies depending on the amount of sun, angle to sun, etc.  
b. If the measured output voltage is within the manufacturer’s specification as defined by the  
specification sheet supplied with the panel, continue with the installation.  
c.  
If the measured voltage is out of specification, call the ABB main office number listed on the  
last page of this guide for a replacement panel.  
2. Connect the solar panel cable to the CHARGER/EXT PWR terminals as shown in Figure 5-2.

7.2  
Configure Ethernet (network) communication  
To configure the RMC for network communication, determine the required network topology first. The  
embedded Ethernet switch on the RMC can be configured to support a single network or two networks. In  
1 Network mode, both Ethernet ports are assigned to one network. In 2 Network mode, each Ethernet  
port is assigned to a separate network.  
In 1 Network mode, you can use one Ethernet port for the uplink connection to the corporate  
WAN (through a local or field network switch), and the other port to connect additional devices  
on the field network (in daisy-chain fashion). This configuration forms a logical LAN where a  
network switch, an RMC, and an additional device communicate on a single network. Each of the  
devices on this network must have a unique and valid IP address with the same subnet number.  
The network traffic on one port is “visible” on the other. To manage devices remotely, establish a  
remote TCP/IP connection with the RMC and, through the RMC, to the attached device(s). The  
RMC switches between the network and the device.  
In 2 Network mode, you can define two networks. These networks are separate and therefore  
traffic on one is not “visible” on the other. If one port is used to connect to the corporate WAN,  
and the other port to a field network, the field network traffic is isolated from the corporate  
network traffic. Remote access to the RMC will require the IP address assigned to the Ethernet  
interface used to connect to the WAN. Remote access to the devices directly connected to the  
RMC will not be possible without an external router at the field. The external router is required  
for communication between the two separate networks.  
The Ethernet interface supports static (manual) or dynamic (DHCP) IP addressing. Static addressing is  
recommended. Follow the procedure that applies to the required topology and Ethernet mode.  
2105551MNAD | RMC-100 | 27  
     
IMPORTANT NOTE: The RMC default Ethernet mode is 1 Network (2-port switch mode).  
Ethernet ports are enabled by default.  
IMPORTANT NOTE: If you are connected to one of the Ethernet ports to configure the  
RMC-100, changing the Ethernet configuration and restarting the interface will cause you to  
lose connection. Make sure to configure your laptop with an IP address compatible with the  
new IP address assigned to the RMC. Re-establish connection using the new RMC IP address  
after the device restarts.  
7.2.1  
Configure the RMC for 1 Network mode (2-port switch)  
To configure the network parameters:  
1. Connect the Ethernet cable from the RMC to the network communication equipment (hub, switch,  
router, etc.).  
2. Verify the Ethernet port LED is green (the network Ethernet link is on).  
3. Start PCCU on the laptop.  
4. Configure the network parameters:  
a. Select Communications on the PCCU navigation tree. The Communications Setup tab  
displays.  
b. Select the Networking tab (Figure 7-5).  
c.  
Verify that the Ethernet Mode is set to 1 Network (default).  
d. Verify that the Ethernet interface State is set to Enable.  
e. If using DHCP for dynamic addressing, set DHCP to Enable.  
f.  
If using static addresses, type each of the parameters: IP Address, Default Gateway, and  
Subnet Mask.  
Figure 7-5: Network communication for 1 Network mode  
5. Click Send. The device saves the updated configuration.  
6. Click Restart. A warning displays to confirm.

7. Click Yes.  
8. Click OK.  
9. Verify that the configuration is correct. If DCHP is enabled, ensure the RMC has obtained its  
required IP parameters (the IP parameter fields must be automatically populated after the  
restart).  
10. Ping the device from the WAN or field network. The RMC should reply to the ping from the  
network.  
11. If connecting another device to the RMC-100 in daisy chain fashion, configure the device with a  
unique IP address in the same subnet as the IP address configured on the RMC.  
12. Verify that you can reach the connected device by pinging its IP address.  
7.2.2  
Configure the RMC for 2 Network mode  
To configure network parameters:  
1. Connect the Ethernet cable from the RMC to the network communication equipment (hub, switch,  
router, etc.).  
2. Verify the Ethernet port LED is green (the network Ethernet link is on).  
3. Configure the Ethernet mode.  
a. Select Communications on the PCCU navigation tree. The Communications Setup tab  
displays.  
b. Select the Networking tab (Figure 7-5).  
c.  
Verify that the Ethernet Mode is set to 2 Networks. The screen displays parameter fields for  
two interfaces since each port will be assigned to a separate network.  
4. Configure Ethernet interfaces for the appropriate subnet. For each interface:  
a. Verify that the Ethernet interface State is set to: Enable.  
b. If using DHCP for dynamic addressing, set DHCP to: Enable.  
c.

Figure 7-7: Network communication for 2 Network mode  
7.3  
Expand serial communications  
The RMC supports serial communication expansion through ABB XIOs or third-party Ethernet-to-Serial  
devices. Connection with this type of equipment requires networking communication over Ethernet.  
Ensure all devices have valid and unique IP addresses. Static IP addressing for devices is recommended.  
7.3.1  
Expand with ABB’s XIO  
The RMC supports serial port expansion through ABB’s Extendible IO devices (XIOs). The RMC can obtain  
measurement data from peripherals such as measurement transmitters connected to XIO COM ports. The  
RMC-XIO combination provides an integrated solution designed to transparently handle devices on XIO  
remote ports as if they were local ports on the RMC. The two options to implement RMC-remote device  
communication are:  
Use the RMC’s XIO Interface application for RMC-XIO communication.  
Use the XIO’s Ethernet-to-Serial Passthrough application for RMC-XIO communication.  
XIOs can be co-located with an RMC on the same cabinet or be in their own enclosure at a distance from  
the RMC in the same field. RMC-XIO communication is over Ethernet. For additional details, refer to the  
XIO user manual. See Additional information for a link to the document.  
IMPORTANT NOTE: The two configuration options for connection with the XIO (XIO  
Interface and Ethernet-to-serial passthrough) provide complete and integrated statistics for  
monitoring and troubleshooting. The XIO supports PCCU as the configuration interface for a  
fully integrated and seamless solution.  
7.3.2  
Expand with third-party serial-to-Ethernet module  
The RMC also supports serial port expansion through third party Serial-to-Ethernet modules. The RMC  
can obtain measurement data from peripheral devices such as measurement transmitters connected to  
30 | RMC-100 | 2105551MNAD  
       
the third-party devices performing Ethernet-to-Serial passthrough. The configuration instructions for the  
third-party device are provided from their manufacturer. For additional details, refer to the RMC-100 user  
manual. See Additional information for a link to the document.  
IMPORTANT NOTE: Using a third-party serial-to-serial Ethernet device does not provide  
any integrated monitoring or troubleshooting capabilities as is provided when using the  
XIOs. The configuration of the device requires the vendor’s user interface which is separate  
from ABB’s PCCU.

Expand I/O capacity with the ABB XIO  
The RMC supports I/O expansion through ABB’s Extensible IO devices (XIO). The RMC can poll and write  
from/to peripherals connected to TFIO Modules installed on the XIO. The RMC’s XIO Interface application  
is designed to handle communication transparently with the TFIO modules as if the modules were directly  
connected to the RMC.  
XIOs and directly attached TFIO modules can be co-located with an RMC on the same cabinet or be in  
their own enclosure at a distance from the RMC in the same field. RMC-XIO communication is over  
Ethernet. For additional details, refer to the XIO user manual and the I/O Interface Application guide.  
See Additional information for links to the documents.  
9 Configure directly attached TFIO interfaces  
To scan and transmit data using the TFIO modules, the RMC TFIO interfaces must be enabled. Connected  
TFIO modules are detected only when the interfaces are enabled. This procedure describes how to enable  
the TFIO interface on the RMC.  
Refer to the IO Interface application guide for additional details to configure and troubleshoot  
communication with TFIO modules. See the Additional information section for a link to the guide.  
IMPORTANT NOTE: The TFIO-A interface is enabled by default. The TFIO-B is disabled by  
default.  
IMPORTANT NOTE: PCCU32 version 7.68 and later support TFIO module hot swap and  
additional configuration and troubleshooting options not available on earlier versions of  
PCCU.  
To verify or enable communication with TFIO modules:

For specific module setup, expand either TFIO-A Modules or TFIO-B Modules on the  
navigation tree and select the desired modules for further configuration.  
10 Enable for MQTT support  
MQTT supports connection of the RMC-100 to a service provider or private cloud. It may require  
authentication certificates for the device. Consult with your IT administrator for configuration options or  
requirements when using certificates.  
NOTICE – Cybersecurity risk: The RMC-100 is not an internet-facing device. Do not connect  
directly to the Internet. An MQTT gateway is required between the Digital Oilfield and the RMC. If  
the customer’s corporate network firewall is compromised, the RMC-100 would be at risk without  
the MQTT gateway.  
Enable MQTT and REST (MQTT configuration interface):  
1. On the PCCU Entry mode navigation tree, select Communications>Services (Figure 10-1).  
36 | RMC-100 | 2105551MNAD  
   
Figure 10-1: RMC-100 Services  
2. Select the MQTT Service checkbox (Figure 10-2). The MQTT REST Service activates.  
3. Select the MQTT REST Service checkbox. This allows access to the MQTT configuration interface  
from a web browser. Once configuration for MQTT is complete, the REST service can be disabled  
for security.
