Expand Serial Communication Capacity; Expand With Abb's Xio; Expand With Third-Party Ethernet-Serial Devices; Configure Input And Output - ABB RMC-100 User Manual

IMPORTANT NOTE: Any TCP/IP connection is lost when the RMC IP address changes and the
interface restarts. Reconfigure the laptop or PC with an IP address compatible with the new RMC IP
address to reestablish connection.

Expand serial communication capacity

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. See section
4.8.1

Expand with ABB's XIO

The RMC supports serial port expansion through ABB's Extendible IO devices (XIOs). 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 RMC can obtain measurement data from peripherals,
such as measurement transmitters, connected to XIO COM ports. The following applications are used
to increment serial port capacity:
–
The XIO Interface Application on an RMC: Supports RMC application access to serial
communication applications interfacing with remote devices connected to an XIO. Applications
on the XIO are exported to the RMC and are visible from there as if local to the RMC.
–
The Ethernet-Serial Passthrough Application on an XIO: Supports transparent Ethernet-serial
communication conversion or TCP Gateway functions. The XIO behaves as converter/tunnel for
serial communication over TCP connections.
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, or the individual guides for each application: The XIO Interface or
Ethernet-Serial Passthrough Application Guides. See
documents.
IMPORTANT NOTE: The two configuration options for connection with the XIO (XIO Interface and
Ethernet-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.
4.8.2

Expand with third-party Ethernet-serial devices

The RMC also supports serial port expansion through third party Ethernet-serial devices. The RMC can
obtain measurement data from peripheral devices such as measurement transmitters connected to
the third-party devices performing Ethernet-serial passthrough. For an example of connection to a
third-party converter see section
IMPORTANT NOTE: Using a third-party Ethernet-serial device does not provide any integrated
monitoring or troubleshooting capabilities as is provided when using ABB's XIOs. The configuration
of the device requires the vendor's user interface which is separate from ABB's PCCU. In addition to
Ethernet-Serial conversion, the XIO also provides full controller capabilities, which third-party
.
converters may not support. The XIO is recommended when seamless integration and flexibility is
required.
