ABB RMC-100 - Configuring the MOXA Module

2105552MNAE | RMC-100 | 203
10.1 Configuration overview
The example described in this section includes a MOXA module and an ABB XMV as the measurement
transmitter with which the RMC communicates. This scenario assumes:
– RMC COMM 1 and COMM 2 are unavailable or additional serial capacity is necessary.
– The RMC is connected to a network. There is also an available connection for the MOXA module
on the same network.
– Valid IP addresses are available for both the RMC and the MOXA module.
IMPORTANT NOTE:
Both the RMC and the MOXA module must have valid IP addresses to
communicate. Devices such as the XMV
transmit measurement data in real-time, so the TCP/IP
connection between the RMC and the Ethernet
-to-serial device must be reliable (the IP
configuration must remain intact all the time). To prevent loss of IP configuration, configure both
devices with sta
tic IP addresses.
Static IP address configuration does not depend on network connectivity as dynamic addressing
does. Use of DHCP for device IP addressing in this scenario could cause measurement data loss
during a network outage or disconnection. Network
connectivity should never affect local
communication with measurement or control peripherals.

Ethernet-to-Serial device
Ethernet
interfaces
Verify that the Ethernet interface is
enabled (In PCCU Entry mode, on the
navigation tree, select Communications
then the Networking tab): Ensure the
State of the interface is set to Enable.
Consult MOXA documentation for details to
enable the Ethernet interface on the
module.
Network (IP)
Parameters
Do not enable DHCP.
Change default IP parameters for valid IP
parameters and restart the interface.
In PCCU Entry mode, on the navigation
tree select Communications then the
Networking tab. Enter valid IP
parameters (obtained from the network
administrator). They must be on the same
subnet as the Ethernet-to-serial device.
Consult MOXA documentation for details to
configure static addressing (ensure DHCP
is disabled) and manually configure valid
IP parameters (obtained from the network
administrator). Must be on the same
subnet as the RMC.
Serial interfaces
In PCCU Entry mode, on the navigation
tree select Communications, then on the
Communication Setup tab, add the
communication application appropriate for
the serial device type and configure
desired serial parameters. Serial port
parameters must match those on the
MOXA module and serial devices. See
section
10.3 Configure the RMC Ethernet
interface to support MOXA®.
Consult MOXA documentation for serial
port configuration. Make sure to match
serial interface parameters to the attached
serial device.
IMPORTANT NOTE:
For other third-party devices, consult vendor documentation for steps to
enable the Ethernet
interface, and configure network (IP) and serial port parameters. Details of
configuration depend on the implementation of vendors, but standard Ethernet and serial interfaces
should be interoperable.
10.2 Configure the MOXA
®
module
This procedure describes how to configure the MOXA
®
module to operate with the RMC. This includes
manually setting up the module’s IP network parameters (static addressing), the serial port
configuration, and the mode of operation.
