Overview of LIOM
LIOM as an integration solution
The Legacy Input/Output Link Module (LIOM) is an integration
Controller designed for
integrating the LCS621 serial I/Os with the Experion Process
Knowledge System
(EPKS). The LIOM resides in the Experion PKS chassis, replacing the
LCS620
processor rack. As an integration solution, the LCS620 ladder logic
programming has
been replaced with the LIOM function block programming. The
Experion Control
Builder has replaced the Loader tool used in LCS620 for building
control strategies. The
LCS621 serial I/O subsystem has been reused in LIOM without any
modifications. For
information about I/O modules, see I/O Modules supported by LIOM.
LIOM is a doublewide, two-slot module in the EPKS chassis. The LIOM
together with
other standard modules in the EPKS chassis replaces the LCS620
processor rack. By
performing a dual role of a Controller and a serial link interface,
the LIOM replaces the
LCS620 processor and the Serial Link Module (SLM) in the LCS620
processor rack. The
LCS621 I/O subsystem has been integrated with EPKS without any
modifications.
For serial interfacing, the LIOM module has two serial ports
through which
communication with the serial I/O subsystem is established. As
illustrated in the
architecture diagram, the serial link from LIOM begins with the
RJ-45 cable that
terminates at one end of the Phoenix Contact RJ-45 connector. The
Belden cable from
the Serial I/O Module (SIOM) in the I/O rack terminates at the
other end of the Phoenix
Contact RJ-45 connector. The serial communication continues from
SIOM-to-SIOM
through the Belden cable.
The supervisory network communication is established through the
ControlNet Interface
(CNI) or the Fault Tolerant Ethernet Bridge (FTEB) module that
resides in the EPKS
chassis with LIOM.
