21.2.12 Serial and LON communication module (SLM)
21.2.12.1 Introduction
The serial and LON communication module (SLM) is used for SPA, IEC
60870-5-103, DNP3 and LON communication. The module has two optical
communication ports for plastic/plastic, plastic/glass or glass/glass. One port is used
for serial communication (SPA, IEC 60870-5-103 and DNP3 port) and one port is
dedicated for LON communication.
21.2.12.2 Design
The SLM is a PMC card and it is factory mounted as a mezzanine card on the NUM
module. Three variants of the SLM are available with different combinations of
optical fiber connectors, see figure
537. The plastic fiber connectors are of snap-in
type and the glass fiber connectors are of ST type.
