4.7 Configure serial communication applications (COM
ports on XIO-04 and XIO-08)
This section describes how to configure the XIO and its communication applications to add serial port
capacity to the RMC. Communication applications assigned to COM ports are instantiated in the XIO but
are managed (visible) from the RMC.
RMC-XIO communication takes place through the XIO Interface (client) – XIO Server connection. This
connection must be successfully established and stable as described in section 4.6.4 Configure the RMC
.
The RMC retrieves measurement data captured on the XIO COM ports and feeds it to its local
measurement applications.
A single XIO Interface instance on the RMC can manage communication with
all COM ports on an XIO. Additional XIO Interface instances are required for additional XIOs. Use a
naming convention for the XIO interface instances which allows easy identification of the associated
XIO.
Configure COM 1 - COM 8 communication ports to connect one or more peripheral serial devices. These
ports are software-configurable to support RS-232, RS-422, and RS-485.
Configure the ports with the application that supports the type of peripheral. For ABB Totalflow
peripherals, use special-purpose communication applications such as the XMV Interface.
The Totalflow Generic Com App supports third-party peripherals. It is
recommended to configure the COM port for Ethernet
-Serial Passthrough when connecting to third-
arty peripherals. Refer to section 4.8 Configure Ethernet-Serial Passthrough.
