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.

7.2 Configure Ethernet (network)

7.3.1

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

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

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
